India’s Railway Transformation

India’s Railway Transformation: The 11,000-Kilometre Expansion That Could Reshape Passenger and Freight Mobility

By Dhinakar Rajaram

An essay on railway capacity, the seven high-density corridors, freight and passenger mobility, and the possible transformation of inter-city travel in India

Reading time: Approximately 18–22 minutes


Foreword

There are announcements concerning Indian Railways which appear, at first sight, to be matters of engineering and infrastructure. A new line is sanctioned. A railway station is rebuilt. A section is electrified. A new train is introduced. A bridge is constructed.

Yet some railway decisions have consequences extending far beyond the physical infrastructure itself.

The recent announcement concerning the four-laning of approximately 11,000 kilometres of seven high-density railway routes belongs to this latter category.

These routes represent only about 16 per cent of the railway network, yet they carry approximately 41 per cent of the total railway traffic. The figure is striking because it reveals where a disproportionate share of the country's railway demand is concentrated.

The seven routes are:

  • Delhi–Howrah
  • Howrah–Chennai
  • Chennai–Mumbai
  • Mumbai–Delhi
  • Delhi–Chennai
  • Mumbai–Howrah
  • Delhi–Guwahati

The terminology requires a small clarification. These are not seven isolated railway lines in the ordinary sense of a single pair of tracks running uninterrupted from one city to another. They describe major high-density traffic corridors connecting India's principal metropolitan, industrial and commercial regions.

The proposal to move towards four tracks across the high-density network is therefore better understood as a major capacity augmentation programme than merely as a conventional track-doubling exercise.

That distinction matters.

A railway is not simply a collection of tracks. It is an intricate operating system consisting of permanent way, signalling, electrification, stations, junctions, bridges, tunnels, level crossings or their replacements, maintenance facilities, rolling stock, train paths, crew management and traffic regulation.

Adding infrastructure to one part of that system can have consequences throughout the network.

This essay examines what the proposed expansion could mean for Indian Railways, for passengers and freight, and particularly for the next phase of India's faster inter-city railway services.

It also considers a question which I find increasingly interesting: whether, during the coming decade, modern railway services could capture a substantially larger share of the journeys for which travellers today consider air travel.


Article 51A(h), Scientific Temper and Public Discussion

I regard informed public discussion, examination of evidence and the willingness to question assumptions as being consistent with the spirit of inquiry referred to in Article 51A(h) of the Constitution of India — to develop the scientific temper, humanism and the spirit of inquiry and reform.

This essay is therefore written as an examination of a public infrastructure development, using publicly available information and clearly distinguishing established facts from interpretation and forward-looking assessment.


About the Author

I am Dhinakar Rajaram, an Indian writer with longstanding interests in science, technology, astronomy, history, geography, engineering, music and contemporary affairs.

My interest in railways is not confined to trains as machines. I have always found the railway to be an extraordinary intersection of geography, engineering, economics and human movement.

A railway line changes the meaning of distance.

A junction changes the direction of commerce.

A bridge over a river removes a geographical barrier. A tunnel through a mountain alters an established route. A railway station can transform a town into a centre of trade and, over time, contribute to the growth of an entire urban region.

My earlier writings on Indian railways have approached the subject from different historical, regional, geographical and strategic perspectives. Taken together, they form a continuing exploration of how railway infrastructure has shaped, and continues to shape, the movement of people, goods and ideas across India.

In Before Bombay: The Forgotten Railways of the Madras Presidency, I examined the less remembered origins and early development of railway activity in the Madras Presidency, looking beyond the familiar narrative of the first passenger railway service from Bombay and towards the earlier railway experiments, proposals and developments that formed part of the wider history of railways in southern India.

In The Cauvery Delta Railways, I turned to a more regional history, examining the development and significance of railway connectivity across the fertile Cauvery Delta. That story illustrates how railway lines were not merely instruments of long-distance transport, but also became closely connected with agriculture, commerce, towns, markets and the economic life of the regions through which they passed.

In A Vision on Rails: Imagining India’s Northern Railway Gateway to Eurasia, I considered the railway from a much larger geographical and strategic perspective. The essay examined the possibility of future railway connectivity extending northwards from India towards the wider Eurasian transport system, and the relationship between geography, infrastructure, trade and strategic connectivity.

These earlier essays provide useful points of reference for the present discussion. The first two look backwards into the history of railway development and its regional consequences; the third considers the railway as an instrument of future national and Eurasian connectivity. The present essay addresses another fundamental question: how much capacity will India's railway system require to carry the passenger and freight traffic of the decades ahead?

The proposed four-tracking of approximately 11,000 kilometres of high-density railway routes brings that question into sharp focus. It is, in a sense, another chapter in the same long railway story — from the laying of the first lines, through the development of regional networks, to the creation of a high-capacity national railway system capable of supporting India's next phase of economic and social mobility.

This essay turns to another aspect of the railway: capacity.

For a railway network, capacity is ultimately the ability to move more trains, more people and more goods safely and reliably through the same geographical space.


Preface: When Sixteen Per Cent Carries Forty-One Per Cent

One statistic provides the starting point for this entire discussion.

Approximately 11,000 kilometres of high-density railway routes represent only about 16 per cent of the network, yet account for approximately 41 per cent of total railway traffic.

Put another way, a relatively small part of the railway system is carrying a remarkably large proportion of the national traffic load.

This is the classic problem of a network whose arteries have become more heavily used than the surrounding system.

India's population, cities, industries, ports, agricultural markets and logistics centres have developed unevenly across the country. Railway traffic has consequently followed the same pattern.

Delhi, Mumbai, Chennai, Kolkata, Guwahati and the major industrial and commercial regions connected to them generate enormous movements of passengers and goods.

The railway routes linking these regions therefore become the principal arteries of national mobility.

As traffic increases, the question is no longer simply whether more trains can be introduced.

The question becomes whether the infrastructure can accommodate them without compromising punctuality, maintenance, safety and the movement of other trains.


1. The Seven High-Density Corridors

The seven corridors identified in the recent announcement form a broad framework linking some of India's most important metropolitan and economic regions.

Corridor Strategic significance
Delhi–Howrah Connects the national capital with eastern India and the Kolkata metropolitan region
Howrah–Chennai Major east-coast axis linking eastern and southern India
Chennai–Mumbai Major west–south industrial and commercial connection
Mumbai–Delhi One of India's most important north–west economic corridors
Delhi–Chennai Long-distance north–south axis connecting the national capital with southern India
Mumbai–Howrah Major west–east corridor connecting Mumbai with eastern India
Delhi–Guwahati Strategic connection between northern India and the North-Eastern region

The routes are important not merely because they connect famous cities. They connect economic regions.

Behind every passenger train are millions of individual journeys. Behind every freight train are factories, mines, power stations, warehouses, ports, agricultural markets, retailers and consumers.

A railway corridor is therefore an economic corridor whether or not it is officially described in those terms.


2. The Difference Between More Trains and More Capacity

It is tempting to assume that a railway can solve rising demand simply by running more trains.

There is, however, a practical limit.

A railway timetable is a carefully balanced sequence. Every train requires a path through the network. Passenger trains, freight trains, maintenance blocks, empty-stock movements, locomotive movements and other operational requirements all compete for available paths.

On a heavily utilised double-track section, the timetable can become increasingly dense.

Once trains are running at close intervals, even a small disruption can propagate through the timetable.

A delayed express may affect another service. A freight train waiting for a path may affect subsequent freight movements. A maintenance requirement may have to be fitted into a narrow window.

The result is what railway engineers and operators understand well: capacity is not simply the number of physical tracks; it is usable operational capacity.

This is why additional tracks can be transformative.


3. What Four-Tracking Actually Changes

Moving from two tracks to four does not mean that railway capacity automatically becomes exactly twice as useful.

The actual benefit depends upon signalling, junction capacity, gradients, station layouts, traffic patterns, electrification, rolling stock and operational planning.

Nevertheless, four tracks provide something extremely valuable: room to manoeuvre.

With additional lines, railway planners have greater scope to organise different classes of traffic.

For example, passenger services requiring faster running can potentially be managed separately from slower freight movements on appropriate sections. Overtaking becomes easier to organise. Maintenance blocks can be planned with greater flexibility. Additional passenger services can be introduced without necessarily forcing every other train into an increasingly compressed timetable.

In railway terminology, the network gains greater operational flexibility.

That flexibility can sometimes be more valuable than the raw increase in track kilometres suggests.


4. Passenger and Freight: Two Different Operating Requirements

Indian Railways has the unenviable task of moving both people and goods across the same national network.

A passenger travelling on a Vande Bharat service and a freight train hauling several thousand tonnes do not have identical operational characteristics.

A modern passenger train may accelerate comparatively quickly, maintain a high average speed and make relatively limited station stops.

A heavy freight train behaves differently. Its mass, braking characteristics, length and acceleration profile impose different operational requirements.

On a congested railway, these differences matter.

It is rather like attempting to operate a motorway carrying high-speed cars, slow heavy lorries and emergency vehicles on only two narrow lanes. The problem is not merely the number of vehicles; it is the interaction between different types of traffic.

Four-line railway corridors can provide the infrastructure necessary to manage such traffic more intelligently.


5. The Freight Railway Behind the Passenger Railway

Passenger trains naturally attract public attention. Freight trains generally do not.

Yet the freight railway is fundamental to India's economy.

Indian Railways carries coal, iron ore, cement, foodgrains, fertilisers, petroleum products, containers and numerous other commodities. In June 2026 alone, Indian Railways reported freight loading of approximately 142 million tonnes, while cumulative freight loading during the first quarter of financial year 2026–27 exceeded 419 million tonnes.

Such numbers illustrate the scale of the task.

India's industrialisation will require ever greater movement of raw materials and finished goods.

If railways can carry a greater proportion of that traffic efficiently, the consequences extend beyond the railway balance sheet.

Reliable freight movement can reduce logistics bottlenecks, improve supply-chain predictability and strengthen the competitiveness of manufacturing and commerce.

There is also an environmental dimension. Rail transport can move large quantities of freight with considerably lower energy consumption per tonne-kilometre than road transport under suitable operating conditions.

Thus, additional railway capacity is not merely a transport investment.

It is an economic investment.


6. The Passenger Railway Is Changing

At the other end of the equation is the passenger.

Indian railway passengers are no longer uniformly travelling in the same manner as they did several decades ago.

There is increasing demand for speed, punctuality, cleanliness, comfort, reliable catering, improved information systems and predictable journey times.

The emergence of Vande Bharat is part of this wider transformation.

According to Ministry of Railways information, 162 Vande Bharat services were operating by March 2026. During financial year 2025–26, approximately 3.98 crore passengers travelled on Vande Bharat services, an increase of about 34 per cent over the preceding year. Since their introduction, the services had carried more than 9.1 crore passengers over nearly one lakh trips.

Those figures are important because they demonstrate that demand for faster and more modern railway travel is not merely theoretical.

Passengers are using the services.

And where demand is strong, capacity becomes the next question.


7. Vande Bharat and the Question of Infrastructure

A modern train can only perform as well as the railway environment in which it operates.

It is possible to design a train capable of high speeds. It is considerably more difficult to provide an entire railway corridor capable of allowing that train to exploit its design characteristics consistently.

Track geometry, signalling, curves, gradients, junctions, level crossings, station approaches and the presence of slower trains all influence actual journey times.

This is one reason why railway modernisation cannot be judged solely by the specification of the rolling stock.

The train and the infrastructure must be considered as one system.

A faster train running on a congested railway may offer only limited additional benefit. A faster train running on a high-capacity, well-signalled and carefully engineered corridor is a different proposition.

This is where the proposed four-laning becomes particularly relevant to the future of Vande Bharat.


8. The Arrival of the Vande Bharat Sleeper

The transformation is no longer confined to daytime chair-car services.

The Vande Bharat Sleeper represents an attempt to extend the same philosophy of modern, faster railway travel to long-distance overnight journeys.

The first Vande Bharat Sleeper service, between Howrah and Kamakhya, entered regular operation in January 2026. The Ministry of Railways has also planned the manufacture of 260 Vande Bharat Sleeper trainsets in a phased programme.

The sleeper train is significant because India's geography does not permit every long-distance journey to be transformed into a short daytime trip.

For many routes, overnight travel remains practical.

The question is therefore whether an overnight modern railway service can provide an experience sufficiently comfortable, dependable and time-efficient to compete with the convenience associated with air travel.

That is a different contest from simply comparing maximum speeds.


9. The Real Competition with Aviation Is Door-to-Door

Whenever rail and air travel are compared, the aircraft's cruising speed is usually placed beside the train's operating speed.

That is only part of the story.

A passenger's journey begins at home.

There is the journey to the airport, check-in, security screening, waiting, boarding, taxiing, the flight itself, baggage collection and finally the journey from the destination airport to the city or neighbourhood where the passenger is actually going.

A railway station, by contrast, is frequently located much closer to the urban centre.

This gives railways a structural advantage on selected city-pair markets.

The relevant measure is therefore not simply train time versus flying time.

It is door-to-door travel time.

If railway infrastructure permits a modern train to cover a journey in a competitive period, the passenger may reasonably ask whether the additional procedures associated with air travel are worth the time saved in the air.

This is particularly relevant on medium-distance inter-city routes.


10. The Ten-Year Question

This leads to the question which I believe deserves serious consideration.

Could faster railway services capture a substantial share of passenger journeys that would otherwise have been made by air during the next ten years?

I believe the answer could be yes on a significant number of city-pair routes, provided that the necessary infrastructure is delivered.

This is not a proposition that railways will replace aviation.

India is too large, geographically diverse and economically complex for such a conclusion.

For very long journeys, particularly where a railway journey would consume many additional hours, aviation will retain an important advantage.

But the market is not homogeneous.

There is a considerable middle ground between a short journey for which rail is obviously preferable and an extremely long journey for which flying is plainly faster.

That middle ground is where modern inter-city rail can be particularly competitive.


11. Why Capacity Could Become the Deciding Factor

Suppose passenger demand for faster trains continues to increase.

Suppose Vande Bharat services continue to expand.

Suppose sleeper services become more widespread.

Suppose existing passenger services continue to grow and freight demand also rises.

Then the railway faces a simple arithmetic problem.

More trains require more usable paths.

More freight requires more capacity.

More passenger services require more capacity.

Maintenance requires capacity.

Safety requires operational margins.

And future growth requires capacity that does not yet exist.

This is precisely why a four-track high-density network can be so consequential.


12. Signalling: The Invisible Railway

To the passenger standing on a railway platform, signalling is almost invisible.

Yet signalling is one of the principal determinants of how closely trains can safely follow one another and how effectively the available railway capacity can be used.

Modern railway expansion must therefore be accompanied by modern signalling and train-control systems.

India's Kavach automatic train protection system is part of this broader technological transition. Government information published in 2026 reported that Kavach had been deployed on more than 3,100 route kilometres, with implementation underway across a much larger network.

Capacity expansion without appropriate signalling would leave part of the potential benefit unrealised.

The railway of the future is therefore not merely a railway with more rails.

It is a railway with better track, signalling, electrification, rolling stock and traffic management working as an integrated system.


13. Electrification and the Changing Railway

The transformation is also taking place beneath the overhead wires.

According to government data, railway electrification had reached approximately 99.6 per cent of the network by March 2026, covering about 69,873 route kilometres.

This is significant because electric traction provides an important foundation for a modern high-capacity railway.

Electric locomotives and electric multiple-unit or distributed-traction trainsets can support high-performance passenger operations, while electrified freight corridors reduce dependence upon diesel traction.

When combined with modern signalling and additional tracks, electrification becomes part of a larger systems-engineering transformation.


14. Capacity Is Not Only About Speed

There is a tendency to associate railway modernisation with speed.

Speed is important, but it is not the only measure.

A railway which runs more trains reliably can be more useful to the travelling public than a railway which operates a small number of exceptionally fast trains.

Frequency matters.

Punctuality matters.

Capacity matters.

Interchange matters.

Station accessibility matters.

Reliability matters.

A passenger does not necessarily want the fastest possible train at an inconvenient hour. The passenger wants a dependable service that fits the journey.

That is why four-tracking could ultimately be as important as increasing train speeds.


15. The Importance of Junctions

There is another potential bottleneck which deserves attention: the railway junction.

A four-track route can still be constrained if a major junction has insufficient capacity.

At junctions, trains may have to cross from one line to another. Conflicting movements can restrict the number of trains which can pass through even when the approach tracks themselves have ample capacity.

Consequently, the four-laning of high-density corridors must be accompanied by appropriate remodelling of junctions, station approaches and terminal arrangements.

Otherwise, the railway risks moving the bottleneck from one location to another.

In engineering terms, the weakest link can determine the practical capacity of the entire chain.


16. Stations Will Matter Just as Much

A railway corridor does not end at the station throat.

The passenger experiences the railway through stations.

Modern trains arriving at congested stations can face platform constraints, conflicting movements, turn-around requirements and limited stabling facilities.

The expansion of high-density routes therefore creates an opportunity to rethink station infrastructure as well.

Platform capacity, pedestrian circulation, foot overbridges, lifts, escalators, parking, road connectivity and integration with metro, suburban and bus systems will all influence the actual passenger experience.

The modern railway should not be conceived as a line running from one station to another.

It should be conceived as a mobility system.


17. The Chennai Perspective

For those of us in southern India, the significance of the proposed network is particularly evident.

Chennai lies at the intersection of several important national railway flows.

The Chennai–Howrah axis links the city with eastern India. The Chennai–Mumbai corridor provides a major westward connection. The Delhi–Chennai axis represents one of India's principal north–south railway relationships.

These are not merely railway routes on a map.

They connect Chennai to industrial regions, commercial centres, ports, educational centres, tourism destinations and the national capital.

Greater capacity on these corridors could therefore have consequences extending well beyond the railway passenger.

It could influence freight movement into and out of Tamil Nadu, improve inter-city passenger connectivity and create greater scope for future premium and semi-high-speed services.

The implications for Chennai are consequently both regional and national.


18. The Economic Geography of Four-Tracking

Railways have historically shaped India's economic geography.

Where a railway arrives, markets become accessible.

Where trains become more frequent, commuting becomes easier.

Where freight capacity expands, industries can reconsider their logistics arrangements.

A high-capacity railway corridor can therefore stimulate economic activity along its length.

The seven corridors identified in the recent announcement already pass through some of India's most economically significant regions.

Enhancing their capacity could reinforce existing economic relationships while potentially creating new ones.

This is particularly relevant as India seeks to strengthen domestic manufacturing, logistics, industrial corridors and national supply chains.


19. Railways and Logistics Costs

Transport costs ultimately find their way into the price of goods.

If a manufacturer pays more to move raw materials, the cost of production rises.

If finished goods take longer to reach markets, inventory requirements increase.

If freight movement is unpredictable, businesses require larger logistical buffers.

A reliable railway system can reduce some of these inefficiencies.

The Railway Minister has specifically associated the four-laning initiative with increasing capacity, supporting passenger and freight growth, reducing transport costs and encouraging cleaner mobility.

The importance of the programme therefore lies not merely in the additional kilometres of track.

It lies in what those kilometres may enable the railway to do.


20. The Environmental Argument

Rail transport also has a strategic environmental role.

Moving large quantities of people and goods by rail can reduce dependence on road transport for suitable journeys.

Electrification strengthens that advantage, particularly as the national electricity system itself incorporates an increasing proportion of renewable generation.

However, environmental benefits should not be treated as automatic.

The efficiency of a transport system depends upon utilisation, energy source, route characteristics, rolling stock and operating practices.

The stronger argument is therefore that a high-capacity electrified railway provides India with a powerful platform for lower-emission mass mobility and freight movement.


21. Why the 11,000 Kilometres Matter More Than the Number Suggests

Eleven thousand kilometres is an enormous engineering undertaking.

But the geographical figure alone does not adequately describe its importance.

The significance comes from where those kilometres are located.

If 11,000 kilometres of lightly used branch lines were being upgraded, the national impact would be different.

Here, however, the routes constitute a disproportionately busy part of the network.

That is why a comparatively limited share of the national route network can have such a large systemic effect.

The railway is strengthening its arteries.


22. The Historical Perspective

There is an interesting historical continuity here.

The earliest railway projects in India were driven by practical necessities — transport, commerce, administration, famine relief, movement of materials and access to ports.

As I discussed in Before Bombay: The Forgotten Railways of the Madras Presidency, the history of Indian railways is more complicated than the familiar story beginning with the celebrated 1853 passenger service from Bombay.

Railways developed because geography and economic necessity demanded them.

Nearly two centuries later, the principle remains remarkably similar.

The geography has changed through urbanisation and industrialisation, but the railway is still being asked to solve the problem of moving people and goods across a vast country.


23. From National Network to National Mobility Grid

India is gradually moving towards a railway system in which different forms of rail transport have different roles.

Suburban trains serve dense metropolitan regions.

Conventional express trains provide extensive national connectivity.

Vande Bharat services address faster inter-city travel.

Vande Bharat Sleeper services extend modern semi-high-speed travel into longer overnight journeys.

Amrit Bharat services address affordable long-distance connectivity.

The Mumbai–Ahmedabad High-Speed Rail project represents an entirely different technological category, with a design speed of up to 320 km/h on its approximately 508-kilometre corridor.

These services should not be viewed as competitors within one simple hierarchy.

They can form layers within a national mobility system.


24. Where Does Aviation Fit?

Aviation will remain indispensable to India.

The country is too large and its cities too widely dispersed for rail to replace air transport.

There will always be journeys for which the aircraft is the logical choice.

But railways need not replace aviation to alter the market.

If rail captures a larger share of medium-distance travel, aviation can become more concentrated on routes where its speed advantage is decisive.

That could create a more differentiated transport system.

Rail for the city pairs where door-to-door journey times are competitive.

Air for longer journeys where the time saving is substantial.

Road for dispersed destinations and first- and last-mile connectivity.

Metro and suburban rail for metropolitan movement.

In such a system, competition and complementarity can exist simultaneously.


25. The Airport-to-Railway Shift

My expectation is that the coming decade could see a gradual change in passenger behaviour.

A traveller who once automatically searched for a flight may increasingly compare the flight with a Vande Bharat or another modern inter-city railway service.

The decision will be based upon several factors:

  • total door-to-door journey time;
  • frequency of services;
  • punctuality;
  • fare;
  • station accessibility;
  • airport access time;
  • comfort;
  • baggage requirements;
  • reliability; and
  • the purpose and urgency of the journey.

This is a much more sophisticated competition than simply asking whether a train is faster than an aircraft.


26. What Could Happen by the Mid-2030s?

If the four-laning programme proceeds substantially, and if the associated signalling, electrification, junction remodelling and station improvements keep pace, the railway system of the mid-2030s could look considerably different from today's network.

There could be more passenger paths.

There could be more freight paths.

There could be greater scope for premium services.

There could be more overnight modern trains.

There could be better timetable resilience.

And there could be a more deliberate separation of different traffic patterns.

The real transformation would not be one spectacular railway project.

It would be the cumulative effect of thousands of engineering decisions made across 11,000 kilometres.


27. The Caveat: Four Tracks Do Not Automatically Mean Four Times the Capacity

A sensible discussion must also recognise the limitations.

Four tracks do not automatically translate into four times the usable capacity.

Junctions can remain bottlenecks.

Terminals can remain constrained.

Signalling can limit headways.

Maintenance requirements cannot simply be ignored.

Curves, gradients, bridges and tunnels impose engineering constraints.

Land acquisition can delay projects.

Construction must frequently take place while existing trains continue to operate.

In other words, the physical expansion of the railway is only one part of the undertaking.

The operational railway must be designed around it.


28. Construction While the Railway Keeps Running

This may be one of the most demanding aspects of the entire programme.

India cannot simply close its busiest railway corridors for several years and rebuild them at leisure.

The trains must continue to run while the railway is being expanded.

That requires careful staging.

New embankments may have to be constructed alongside operating tracks. Bridges may require reconstruction or widening. Signalling systems may have to be modified while trains continue to use the existing system. Stations may have to be remodelled without interrupting passenger services.

It is, in effect, rebuilding a road while traffic continues to use it.

The engineering and operational challenge should not be underestimated.


29. The Importance of Execution

Announcements establish direction.

Engineering establishes possibility.

Execution establishes reality.

The eventual success of the programme will therefore depend upon planning, financing, land availability, construction capacity, procurement, project management, safety and coordination between numerous agencies.

India has demonstrated that very large railway programmes can be executed at considerable scale.

The challenge now is to sustain that momentum across a network where trains cannot simply be stopped while the work is carried out.


30. A Railway System Designed for the Next Generation

The most important aspect of this announcement may be that it looks beyond the railway traffic of today.

Infrastructure takes years to design, finance, construct and commission.

A railway line built today may remain in service for many decades.

Therefore, the question is not simply:

How many trains does India need today?

The more important question is:

How many trains will India need when the infrastructure being built today reaches maturity?

That is the proper horizon for railway planning.


31. A New Chapter for Vande Bharat

Vande Bharat has already demonstrated considerable passenger demand. The next stage will be to integrate that demand with the infrastructure required to sustain it.

More trains require more paths.

More paths require capacity.

Capacity requires tracks, signalling, junctions, stations and maintenance infrastructure.

The four-laning programme therefore provides a potential physical foundation for the next phase of the Vande Bharat story.

The train may be the visible symbol.

The railway infrastructure is the machinery behind the symbol.


32. The Larger Economic Consequence

There is a tendency to calculate railway investment in terms of kilometres of track, number of trains or expenditure.

The ultimate measure, however, is the economic activity made possible by that infrastructure.

If a factory receives raw materials more reliably, the railway has created value.

If a passenger reaches another city more quickly, the railway has created value.

If freight can move overnight instead of waiting for a path, the railway has created value.

If a business can operate with smaller inventories because transport is dependable, the railway has created value.

If a traveller chooses rail instead of a road journey, the railway has created value.

The infrastructure therefore has a multiplier effect which cannot be captured merely by counting track kilometres.


33. From Two Tracks to Four — and Beyond

There is also a broader lesson here.

India's railway history has repeatedly been a history of expanding capacity to meet changing national requirements.

Single lines became double lines.

Steam traction gave way to diesel and electric traction.

Manual signalling progressively gave way to more sophisticated systems.

Traditional coaches are increasingly being complemented by modern trainsets.

Now some of the most heavily loaded corridors are being prepared for four-track operation.

This is not the end of the railway transformation.

It is another stage in it.


34. What I Expect from the Coming Decade

I expect the coming decade to be a particularly interesting period for Indian railway travel.

There will almost certainly be continuing debate about railway speeds, fares, comfort and connectivity.

But underneath all these visible aspects will be the less glamorous question of capacity.

Can the railway accommodate the trains that passengers want?

Can it accommodate the freight that industry requires?

Can maintenance be carried out without crippling the timetable?

Can modern signalling extract the maximum practical capacity from the infrastructure?

Can stations and junctions handle the additional traffic?

Can all these elements be brought together as one coherent system?

If the answer is yes, then the consequences could be substantial.


35. Could Rail Take a Larger Share from Aviation?

Here I return to the proposition with which I began.

I believe that, within roughly the next ten years, modern inter-city railway services — particularly Vande Bharat and its evolving variants — could take a substantial share of journeys which passengers might otherwise have made by air on competitive city-pair routes.

The crucial word is competitive.

This will not happen on every route.

It will not happen for every passenger.

And it will not mean the decline of aviation as a whole.

It could, however, produce a meaningful redistribution of the market.

Where the total door-to-door journey time becomes comparable, the railway's advantages in city-centre accessibility, frequency, boarding convenience and potentially lower fares could become increasingly persuasive.

At that point, the question may no longer be:

“Should I take the train or the flight?”

It may become:

“Which mode gives me the better journey today?”


36. The Railway as the Artery of a Growing India

India is entering a period in which mobility will be increasingly important to economic growth.

People will travel more.

Goods will move more frequently.

Cities will expand.

Industrial corridors will develop.

Supply chains will become more complex.

Tourism will grow.

Regional economies will become increasingly integrated.

A railway system designed for an earlier India cannot simply be expected to carry the traffic of a future India without substantial augmentation.

The proposed four-laning of the seven high-density routes is therefore significant because it addresses precisely those parts of the network where demand is already concentrated.


37. The 11,000-Kilometre Question

Ultimately, the importance of this announcement can be reduced to a remarkably simple proposition.

Approximately 11,000 kilometres of railway route carry around 41 per cent of India's railway traffic.

That is an extraordinary concentration of demand.

Strengthening those routes can therefore have an effect disproportionate to their share of the total network.

If the four-laning programme is implemented effectively, it could provide the railway with the breathing space required for the next generation of passenger and freight services.

It could allow the railway to move from a system in which trains compete intensely for scarce paths towards one in which capacity is deliberately engineered around future demand.


38. Conclusion: A Railway Looking Ahead

Indian Railways has never been merely a means of transporting people from one station to another.

It has been one of the principal physical frameworks through which modern India has developed.

The railway connects markets, cities, industries, ports, agricultural regions and people.

Its importance is therefore measured not merely in kilometres of track but in the economic and social activity that those tracks permit.

The decision to move towards four-laning approximately 11,000 kilometres of the country's high-density railway routes should be viewed in that larger context.

These routes account for only about 16 per cent of the network, yet carry approximately 41 per cent of total railway traffic.

The significance is obvious.

India is strengthening the arteries which already carry an exceptionally large share of the national railway load.

For freight, this could mean greater capacity and improved logistics.

For passengers, it could mean more trains, better reliability and greater scope for faster services.

For Vande Bharat, it could provide the infrastructure necessary for further expansion.

For the relationship between rail and air travel, it could mark the beginning of a new contest based not merely on speed but on the total quality and duration of the journey.

And for Indian Railways itself, it could represent a transition from managing congestion towards planning for abundance of capacity.

That, in my view, is the larger story.

The most important railway of the next decade may not be a single new train.

It may be the railway network that makes thousands of such trains possible.

Whether Vande Bharat and its successors will, within the next ten years, divert a substantial proportion of medium-distance air travellers towards the railway remains to be seen.

There are too many variables to make the outcome a certainty.

But the direction is unmistakable.

More capacity. More trains. Better utilisation. Faster journeys. Greater freight movement.

If these elements come together, Indian Railways may enter one of the most consequential phases of its long history.

Beyond the Battery: Why Hydrogen Still Matters in the Future of Transport

Beyond the Battery: Why Hydrogen Still Matters in the Future of Transport

A personal recollection of electric transport, stored energy, hydrogen and the continuing search for a practical replacement for petrol and diesel

© Dhinakar Rajaram 2026

Foreword

Transport technology is often discussed as though the present generation has invented the questions that it is trying to answer. The reality is rather different. The search for an alternative to petrol and diesel has been continuing for well over a century, and both battery-electric propulsion and hydrogen-powered transport have histories considerably older than today's headlines suggest.

My own interest in this subject goes back more than three decades. Some of what I remember comes from what I encountered in the early 1990s; some comes from things I subsequently saw, studied and experienced; and some has acquired a new significance as technologies that once appeared futuristic have begun to return to practical transportation.

This essay therefore combines personal recollection with historical and technological examination. Where an old recollection cannot now be independently established, I have treated it as recollection rather than fact. Where historical records are available, I have allowed the record to speak for itself.

The central question is not whether batteries are good or bad. Batteries are an extraordinary technology and have transformed electric transportation. My question is a different one: how can an electric vehicle replenish its energy quickly enough and conveniently enough to preserve the freedom and flexibility that made petrol and diesel vehicles so successful?

That question leads naturally to hydrogen.

About the Author

I have been interested in technology, transport and engineering ideas for many decades. My interest has never been confined to technologies that happened to be fashionable at a particular time. I have always been intrigued by the engineering problem behind the machine: how energy is produced, how it is stored, how it is transmitted and, ultimately, how it is made useful.

More than thirty-three years ago, I was already thinking about alternative forms of propulsion. In 1990, I designed a concept for a self-generating electric vehicle using a series of batteries and alternators. I mention this not as a claim of a commercially viable invention, but as evidence of the questions that occupied my mind at the time: how could an electric vehicle be made less dependent upon fixed charging infrastructure, and how could its operating range be extended?

My interest in the subject was also reinforced by what I encountered concerning hydrogen-powered transport and by seeing examples of early electric railway technology in India.

At Tambaram, I have personally seen the preserved YCG-1-class electric locomotive displayed at the electric locomotive shed beside GST Road. The actual photographs I once took of the locomotive are unfortunately no longer available to me. The locomotive itself, however, remains part of the railway heritage that can still be seen. Another YCG-1-class locomotive is preserved at the National Rail Museum in New Delhi, although the battery tender associated with these locomotives is no longer preserved with it.

Preface

There is a tendency in present-day discussions to divide transport into two camps: the battery-electric camp and the hydrogen camp. I do not subscribe to such a simplistic division.

A battery is an excellent means of storing electrical energy. An electric motor is an excellent means of converting electrical energy into mechanical motion. There is no contradiction in recognising both facts while questioning whether a large battery is always the most convenient means of supplying energy to every type of vehicle.

The success of petrol and diesel was not due solely to the internal-combustion engine. It was also due to an exceptionally convenient energy-delivery system. Fuel could be carried in a tank, transported almost anywhere, stored for considerable periods and replenished rapidly.

A motorist could enter a petrol station, fill the tank, pay for the fuel and continue the journey. The process usually took only a few minutes. The vehicle did not have to remain stationary for a prolonged period while its energy store underwent an electrochemical charging process.

That simple practical advantage should not be underestimated.

The future of transport therefore involves more than asking which propulsion system is the most efficient on paper. It must also ask how people actually use vehicles: how far they travel, how often they stop, how much payload they carry, how quickly they must return to service and what infrastructure is available to them.

It is from this perspective that I continue to regard hydrogen as a serious contender.

1. The Question That Has Not Gone Away

The fundamental problem of transportation is deceptively simple. A vehicle requires energy, but that energy must somehow accompany the vehicle or remain available along its route.

Petrol and diesel solved the problem through portable chemical energy. A tank could hold a substantial quantity of fuel without adding an impractical amount of weight to the vehicle. The fuel could be replenished rapidly and the vehicle could then travel hundreds of kilometres before requiring another stop.

Electricity solved the propulsion problem admirably, but historically it required a different arrangement. A railway could use overhead wires or a third rail. A tram could remain connected to its electrical supply. A trolleybus could draw current continuously while operating on a fixed route.

The difficulty begins when an electric vehicle must travel freely away from fixed electrical infrastructure.

That is precisely where batteries enter the story.

2. An Indian Example from the 1930s

Long before the present battery-electric vehicle revolution, Indian railway engineers had already confronted the problem of supplying electric traction beyond the reach of overhead electrification.

The South Indian Railway's Madras Beach–Tambaram metre-gauge system was electrified at 1,500 V DC in the early 1930s. Four electric locomotives of the YCG-1 class, built by Hawthorn Leslie with electrical equipment from English Electric, were introduced for this system.

These locomotives were conventional electric locomotives in the sense that they normally drew power from the overhead electrical system. Yet there was a clever provision for circumstances in which they had to work on unelectrified sidings and other sections.

Battery tenders could be coupled to the locomotives.

The battery tender was, in effect, a mobile store of electrical energy. The locomotive remained an electric locomotive, but its dependence upon the overhead line could temporarily be overcome by carrying stored electricity behind it.

This is a remarkable piece of engineering history. The problem was not solved by abandoning electric propulsion. It was solved by finding another way of carrying energy.

I have personally seen the preserved YCG-1-class locomotive at Tambaram, its historic home area. The example at the National Rail Museum in New Delhi also provides a reminder of this early chapter in Indian electric traction. The battery tenders, however, have disappeared from preservation and were lost many decades ago.

To my mind, the principle is worth remembering: electric propulsion does not necessarily mean that the vehicle must always remain physically connected to an electrical supply.

3. The Electric Vehicle Was Already Here More Than a Century Ago

The modern electric vehicle is often presented as though it were a creation of the twenty-first century. It is not. The electric motor, the rechargeable battery and the electric road vehicle all belong to a much older technological history.

When I began thinking about electric and hydrogen-powered transport more than three decades ago, I was therefore not looking at an entirely new idea. I was looking at an old idea whose time, in some respects, appeared to have come again.

Electric vehicles were being experimented with during the closing years of the nineteenth century. By the beginning of the twentieth century, electric cars had already appeared on public roads, and electric taxis were not merely theoretical machines.

One particularly striking example comes from New York. Electric taxis were operating there as early as 1895. The fact is worth remembering because it places electric road transport at the very beginning of the automobile age itself. The internal-combustion engine did not emerge into a world in which electric propulsion was absent. It emerged into a world in which several competing forms of propulsion were already being tested.

Steam, electricity, coal and the internal-combustion engine were all contenders.

The subsequent victory of petrol and diesel was therefore not the inevitable result of one technology being inherently superior in every respect. It was the result of a combination of circumstances: improvements in the internal-combustion engine, the increasing availability of petroleum, the development of roads and fuel distribution, the growing range of motor vehicles and, importantly, the extraordinary convenience of liquid-fuel refuelling.

That last factor deserves particular attention.

Electricity Was Not Defeated by the Motor Alone

The early electric car possessed several virtues. It was comparatively quiet, mechanically simple and free from the starting difficulties associated with early petrol engines. There was no carburettor to adjust, no manual ignition procedure and no exhaust system in the modern sense.

But the battery presented a fundamental limitation.

The vehicle carried its energy store with it, and once that stored electrical energy had been depleted, the vehicle required either time for recharging or another charged source of electrical energy.

Petrol and diesel offered a different proposition. Their energy density was extremely high by the standards of contemporary battery technology, and the energy could be transferred into the vehicle in a matter of minutes.

That difference became increasingly important as motor vehicles were expected to travel farther and perform more demanding work.

Electric Taxis in New York

The history of electric taxis provides an especially useful example because a taxi is not an ordinary private vehicle. It is a working vehicle.

A taxi earns money while it is carrying passengers and loses productive time while it is unavailable for service. Consequently, the question of how quickly its energy can be replenished is not merely a matter of personal convenience. It is an economic consideration.

Electric taxis were already being operated in New York in the 1890s. Their existence demonstrates that the fundamental concept of using an electric motor for urban passenger transport is more than a century old.

The lesson from that period is not that electric vehicles were failures. Rather, it is that the surrounding energy infrastructure is just as important as the vehicle itself.

Britain's Electric Vehicles of the 1940s

A British Pathé film I recently came across provides another fascinating glimpse into this history. The film shows an electric vehicle of the 1940 period operating in Britain.

Seen through modern eyes, such a vehicle can appear surprisingly familiar. It had an electric drivetrain at a time when the motor car was increasingly associated with the internal-combustion engine.

Its existence also reminds us that electric road transport did not disappear entirely during the first half of the twentieth century. It survived in particular niches where its characteristics were useful.

This included urban delivery work and other applications in which vehicles travelled predictable routes, returned to a known base and could be recharged during periods when they were not required for service.

In other words, the limitations of battery technology could sometimes be accommodated by changing the operating pattern of the vehicle.

Sweden and the Battery-Electric Vehicle

Sweden provides another important chapter in this history.

Battery-electric road vehicles were being developed and operated in Sweden during the first half of the twentieth century. During the 1940s, shortages of conventional fuels made electric propulsion particularly attractive for certain forms of commercial transport.

Svensk Elektrobil AB, associated with ASEA, produced battery-electric commercial vehicles. The company's vehicles demonstrate that the electric road vehicle was not merely an inventor's curiosity. It could be engineered for practical work.

The vehicles of the period, naturally, possessed none of the advantages of modern lithium-ion battery systems. Lead-acid batteries were heavy, energy density was low and range was limited. Yet the principle was perfectly sound: electrical energy could be stored chemically and converted into mechanical motion through an electric motor.

The Battery-Swapping Idea Was Not New Either

There is another aspect of the Swedish story that particularly interests me.

I recently came across historical footage showing Swedish electric taxis having their batteries changed. The principle is remarkably simple. Instead of keeping the vehicle stationary while its discharged battery is recharged, the depleted battery is removed and replaced by a charged battery.

From the driver's point of view, this changes the nature of the problem completely.

The vehicle does not have to wait for the battery to regain its charge. The energy store itself is exchanged.

This is precisely the distinction that is once again being discussed in the twenty-first century with modern battery-swapping systems.

The concept is therefore not an invention of the present generation. What has changed is the technology available to implement it.

Modern batteries are vastly lighter and more energy-dense than the lead-acid batteries of the early electric-vehicle era. Automated handling systems can perform battery exchanges with remarkable speed. Digital systems can monitor battery condition, state of charge and usage history.

Yet the fundamental proposition remains exactly the same:

Do not necessarily wait for the energy store to recharge; exchange the depleted energy store for a charged one.

A Lesson From the Past

These examples alter the way in which the present debate about electric vehicles ought to be understood.

Battery-electric vehicles are not a sudden technological revolution without precedent. They represent the latest stage of a development that has been proceeding, with interruptions and reversals, for well over a century.

Likewise, battery swapping is not a fashionable novelty. It is an old engineering response to a simple operational problem.

The problem is time.

A private motorist may be perfectly happy to connect a vehicle to a charger overnight. A commercial operator whose vehicle must remain productive throughout the day may regard the same waiting period very differently.

This distinction is central to my interest in hydrogen.

I do not regard the battery-electric vehicle as an inferior form of transport. Far from it. The battery is an extraordinarily capable energy-storage device, and modern electric vehicles have demonstrated what can be achieved with it.

My question is simply whether every form of transport should be expected to obtain its energy in the same manner.

The history of electric transport suggests otherwise.

Some vehicles were connected continuously to overhead wires. Some carried batteries. Some used battery tenders. Some returned to a depot for charging. Some experimented with battery exchange.

Each was an attempt to solve the same underlying problem:

How can an electric vehicle obtain sufficient energy, with the least disruption to its work?

That question brings us naturally to hydrogen.

4. The Petrol Station Was More Than a Fuel Station

One of the reasons petrol and diesel vehicles became so successful was that their refuelling infrastructure fitted naturally into the rhythm of human travel.

The petrol station became an almost universal piece of transport infrastructure. A driver did not have to plan an elaborate charging schedule. The vehicle could be refuelled whenever convenient.

This characteristic is sometimes overlooked when comparing battery-electric vehicles with conventional vehicles.

The issue is not merely range. It is downtime.

A commercial vehicle that remains stationary for an hour is not merely consuming electricity; it may be losing productive time. A taxi that spends a substantial part of its working day charging is not simply experiencing an energy problem; it is experiencing an operational problem. The same consideration applies to delivery vehicles, buses, long-distance trucks and other high-utilisation vehicles.

Fast charging has improved the situation considerably, and battery technology continues to advance. Nevertheless, the basic difference remains: a battery must accept electrical energy through a controlled charging process, whereas a conventional fuel tank can generally be replenished very rapidly.

This is the principal reason why I remain interested in hydrogen.

5. Hydrogen: Electricity Without a Large Battery

A hydrogen fuel-cell vehicle is still, fundamentally, an electric vehicle.

The difference lies in where the energy is stored.

In a battery-electric vehicle, electricity is stored electrochemically in the battery and delivered to the motor through power electronics.

In a hydrogen fuel-cell vehicle, hydrogen is stored aboard the vehicle. The fuel cell converts the chemical energy of hydrogen into electricity, which then powers an electric motor.

The simplified chain is:

Hydrogen → fuel cell → electricity → electric motor → wheels

Thus, the apparent opposition between an EV and a hydrogen vehicle is somewhat misleading. A fuel-cell vehicle is also an electric vehicle. The real distinction is between different methods of storing and replenishing energy.

6. Iceland and the Hydrogen Experiment

Iceland became one of the most interesting early test beds for hydrogen transport because of its unusual energy circumstances.

The country possesses abundant renewable electricity from hydroelectric and geothermal sources. This created an opportunity to produce hydrogen by electrolysis using electricity and water.

It is important, however, to make a distinction. Iceland did not possess an inexhaustible natural reservoir of usable molecular hydrogen simply waiting to be collected from geysers and thermal vents. The hydrogen used in the transport programme was produced using electricity and water.

The significance of Iceland was therefore its renewable energy base.

The ECTOS project, or Ecological City Transport System, began in 2001. A hydrogen production, compression, storage and dispensing station was inaugurated in Reykjavík in 2003. The first hydrogen fuel-cell buses entered normal public service in October 2003.

Three Mercedes-Benz Citaro fuel-cell buses operated on Reykjavík's public transport system. The hydrogen station produced hydrogen by electrolysis, using fresh water and electricity. The buses were subsequently operated through further demonstration work, including the HyFLEET:CUTE programme.

This is an important correction to a memory I carried for many years. I remember hydrogen transport in Iceland being reported by the BBC around the early period of my recollection. I cannot now establish that Reykjavík buses were actually operating on hydrogen in the early 1990s. The documentary evidence places the public hydrogen-bus operation in 2003.

The memory of the subject was therefore substantially ahead of the actual bus deployment, even if the precise date had become blurred by the passage of more than three decades.

7. What Iceland Really Demonstrated

The Icelandic experiment demonstrated something more significant than merely putting hydrogen into a bus.

It demonstrated a complete energy chain:

Renewable electricity → electrolysis → hydrogen → storage → refuelling → fuel cell → electric motor.

In other words, electricity could be converted into a transportable chemical energy carrier.

That is one of hydrogen's principal attractions.

A battery stores electrical energy directly. Hydrogen stores energy in chemical form and can subsequently be converted back into electricity when required.

Neither method is perfect. Direct electricity-to-battery-to-motor propulsion is generally more energy efficient than producing hydrogen, compressing or storing it, and then converting it back into electricity through a fuel cell.

But efficiency is not the only consideration in transport.

Storage, weight, range, utilisation, refuelling time, infrastructure and operational economics also matter.

8. China Brings Hydrogen to Two Wheels

Recent developments in China have made the hydrogen discussion even more interesting.

Hydrogen fuel-cell two-wheelers are now being developed and deployed in practical applications, including shared mobility, delivery and short-distance urban transport.

In 2025, Chinese regional authorities and industry reports described hydrogen fuel-cell two-wheelers being introduced in cities including Shanghai, Foshan and Chengdu. Some systems use solid-state hydrogen storage rather than conventional high-pressure storage.

In March 2026, China Daily reported that hydrogen-powered shared bicycles in Chengdu had reached substantial operational deployment, with individual vehicles carrying about 100 grams of hydrogen and achieving a reported range approaching 100 kilometres.

China has also moved towards formal technical standards for fuel-cell electric motorcycles and mopeds. National standards published in 2026 cover both safety requirements and testing of energy consumption and range.

This development is significant because it takes hydrogen beyond the image of an experimental bus or an expensive demonstration car.

It places hydrogen in a category where rapid energy replenishment, daily utilisation and operational availability may be more important than absolute drivetrain efficiency.

9. Why I Continue to Look Towards Hydrogen

My preference for hydrogen does not arise from opposition to batteries.

I regard battery technology as one of the great achievements of modern engineering. Batteries have transformed portable electronics, communications, energy storage and transportation.

My concern is narrower.

I question whether a large battery is necessarily the best solution for every vehicle that requires frequent, rapid and flexible replenishment of energy.

Consider a taxi driver, a delivery rider, a long-distance truck operator or a bus company. Their vehicle is not merely a means of transport. It is an operating asset.

Time spent waiting for energy can become a commercial cost.

If hydrogen can be dispensed rapidly, stored safely and supplied economically, a fuel-cell vehicle could retain many of the operational characteristics that made petrol and diesel so convenient while using an electric drivetrain.

The analogy with CNG and LPG is useful. Drivers already understand the basic concept of arriving at a station, connecting a fuelling nozzle, transferring a gaseous fuel into a storage system and continuing their journey.

Hydrogen would require considerably more sophisticated infrastructure and stringent safety systems, but the behavioural model would be familiar: drive, refuel and continue.

10. The Difficulties Hydrogen Cannot Be Allowed to Hide

A serious discussion of hydrogen must also acknowledge its disadvantages.

Hydrogen is not a primary energy source in the same sense as sunlight, wind, coal or natural gas. It is an energy carrier. The energy required to produce it must come from somewhere.

If hydrogen is produced using renewable electricity, the environmental case can be strong. If it is produced from fossil fuels without effective carbon capture, the environmental advantage is greatly reduced.

Hydrogen also presents engineering challenges. It has a very low volumetric energy density under ordinary conditions and therefore requires compression, liquefaction or alternative storage methods. Tanks, pipelines, compressors, dispensers and fuel-cell systems add complexity and cost.

Hydrogen is also not automatically cheaper than petrol, diesel or electricity merely because it can be refuelled quickly.

There is no magic wand.

The hydrogen economy will succeed only if production, storage, distribution, dispensing and vehicle technology become sufficiently economical and reliable.

11. Battery and Hydrogen Need Not Be Enemies

The most sensible future may not involve one technology defeating the other.

Small passenger vehicles used primarily for short urban journeys may be extremely well suited to battery-electric propulsion. Home charging can be particularly convenient for owners who park their vehicles for many hours.

Electricity from the grid can go directly into the battery without the additional conversion steps required for hydrogen.

Hydrogen, on the other hand, may become particularly interesting where range, rapid refuelling, payload and vehicle utilisation are important.

Heavy road transport, long-distance commercial vehicles, buses, specialised fleets and certain industrial applications may therefore justify a different energy architecture.

The answer need not be ideological.

12. The Real Competition Is Not Between Hydrogen and Batteries

After considering the subject for many years, I believe the real competition is not between hydrogen and batteries as such.

It is between different ways of satisfying the requirements of mobility.

A successful transport energy system must provide:

  • adequate range;
  • reasonable vehicle weight;
  • rapid and convenient replenishment;
  • safe energy storage;
  • reliable infrastructure;
  • reasonable operating cost;
  • acceptable environmental performance;
  • high vehicle availability; and
  • freedom from unnecessary interruptions to the journey.

No technology should receive a free pass merely because it is fashionable. Equally, no technology should be dismissed merely because it is unfamiliar.

13. From the YCG Locomotive to the Hydrogen Two-Wheeler

There is an extraordinary thread running through the examples discussed here.

In 1930s Madras, an electric locomotive could use overhead electricity and, when necessary, a battery tender.

In 1940s Sweden, battery-electric commercial vehicles demonstrated that road transport could operate without petrol.

Decades later, battery swapping emerged repeatedly as an idea for overcoming charging delays.

Iceland demonstrated that renewable electricity could be converted into hydrogen and used to power public transport through fuel cells.

China is now applying hydrogen fuel-cell technology to two-wheelers and other commercial transport applications.

The machines have changed, but the question remains remarkably constant:

How do we put sufficient usable energy into a vehicle without making the vehicle impractical or interrupting its work unnecessarily?

14. Thirty-Three Years Later

More than three decades after I first began thinking seriously about hydrogen as a transport fuel, the subject has still not disappeared.

Battery-electric vehicles have advanced enormously. Charging networks have expanded. Battery chemistry has improved. Electric motors and power electronics have become highly sophisticated.

Yet hydrogen has also survived the passing of fashions. It has moved from laboratory experiments to buses, cars, commercial vehicles, industrial equipment and, increasingly, two-wheelers.

I therefore do not see the future as a choice between a battery world and a hydrogen world.

I see a transport system in which different energy-storage methods may coexist because different vehicles perform different tasks.

The passenger car that spends most of the night parked at home may have little difficulty with battery charging.

A taxi, delivery vehicle or heavy truck working continuously may value rapid replenishment much more highly.

For such applications, hydrogen deserves to remain on the table.

That is why, despite my appreciation of battery technology, I continue to look towards hydrogen as a potentially important transport fuel of the future.

15. The Future May Be More Diverse Than We Expect

Technological history rarely proceeds in a straight line.

One technology may dominate for a period and then encounter an application for which another technology proves more suitable. Sometimes an old idea returns after its supporting technology has matured.

Battery vehicles are not new. Hydrogen vehicles are not new. Electric railways are not new. Battery swapping is not new.

What is new is the technological capability available to us today.

We now possess power electronics, advanced electric motors, high-performance batteries, sophisticated fuel cells, improved hydrogen storage systems, digital energy management and renewable electricity generation on a scale that earlier generations could scarcely have imagined.

The sensible course is therefore not to close the door on any technology prematurely.

The ultimate objective is simple: cleaner, safer, more efficient and genuinely convenient mobility.

If batteries can provide it for one class of vehicle, they should be used.

If hydrogen can provide it more effectively for another, hydrogen should not be dismissed.

The road ahead may belong not to one fuel, one battery chemistry or one propulsion system, but to a carefully balanced combination of technologies.

The Adversary Is Watching

Part IV: The Adversary Is Watching

Pakistan’s Turkish Drones, the New Contest for Battlefield Awareness, and the Shadow of Another Conflict

A geopolitical assessment of the emerging military pattern following Operation Sindoor

Foreword

Military history is littered with examples of nations preparing for the last war while the next one quietly takes shape around them. The danger lies not merely in failing to possess the latest weapon. It lies in failing to recognise that warfare itself has altered its habits.

Operation Sindoor demonstrated, among other things, that the modern battlefield can no longer be understood solely through maps, formations and conventional front lines. Drones, missiles, sensors, satellites, electronic warfare, integrated air defence and information networks have become part of a single and increasingly interconnected military environment.

The three preceding essays in this series examined different aspects of that transformation. The first considered the changing geography of warfare and reflected upon warnings concerning the wider battlefield. The second examined the possibility that an adversary, having experienced defeat or disappointment, would study the encounter and alter its methods. The third turned towards the question of persistent surveillance and argued that the ability to see the battlefield early may become as important as the ability to strike it.

Events now being reported during August 2026 provide an opportunity to revisit those arguments.

Pakistan has reportedly begun employing Turkish-made Bayraktar TB2 unmanned aerial vehicles near sensitive sectors of the Line of Control for surveillance and intelligence-gathering. At approximately the same time, open-source flight-tracking observations and subsequent media reporting drew attention to an unusual concentration of Turkish military transport flights into Pakistan, accompanied by reports of Chinese military transport activity.

None of this, by itself, proves that Pakistan has decided upon war.

That distinction must be maintained.

Yet a number of retired military officers and defence commentators have begun to interpret the cumulative pattern as evidence that Pakistan may be preparing for another confrontation. Their assessments are not official intelligence, nor can they establish a timetable or prove political intent. Nevertheless, such observations cannot simply be brushed aside. Military veterans possess professional experience which I do not claim to possess, and when several observers independently begin to notice a developing pattern, the pattern itself deserves examination.

This essay therefore does not predict war. It asks a different question.

What might Pakistan's present military activity mean if viewed not as a collection of isolated incidents, but as part of a larger process of adaptation, preparation and strategic observation?

Preface: A Fourth Look at the Same Horizon

There is a temptation in contemporary strategic commentary to treat every development as a separate headline. A drone is spotted. A transport aircraft lands. A retired general speaks. A government updates a travel advisory. Each event is discussed for a day or two before another headline replaces it.

But military preparation rarely announces itself in a single dramatic gesture.

It is often revealed through accumulation.

A new surveillance platform here. A replenishment flight there. An unusual concentration of military logistics. A strengthening of defence partnerships. A greater emphasis upon unmanned systems. The movement of equipment to air bases. Changes in readiness. A gradual adjustment of doctrine.

Individually, any one of these may have an innocent or routine explanation. Collectively, however, they may justify closer scrutiny.

This is particularly true in South Asia, where geography, history and strategic distrust ensure that military preparations are rarely regarded as politically neutral. The Line of Control is not an abstract line drawn upon a map. It is one of the world's most heavily militarised and politically sensitive frontiers.

The introduction of persistent unmanned surveillance into such an environment therefore deserves attention even when no shot has been fired.

The purpose of this essay is not to sound a trumpet of alarm. It is to examine what can presently be observed, what remains uncertain, and why the distinction between the two is itself important.

The Argument So Far

This fourth essay forms part of a continuing examination of the strategic environment surrounding and following Operation Sindoor.

The fourth essay introduces an uncomfortable but necessary reciprocal question.

If India is strengthening its ability to observe the battlefield, is Pakistan attempting to strengthen its ability to observe India?

The reported deployment of Bayraktar TB2 drones near the Line of Control gives that question a new and immediate relevance.

1. The Adversary Is Watching

For much of the public imagination, a military drone is associated primarily with attack. One imagines a missile descending upon a vehicle, a building or a military installation.

Yet the most important function of an unmanned aircraft may sometimes be the one least visible to the public.

It watches.

A medium-altitude, long-endurance platform does not necessarily have to release a weapon to influence the battlefield. Its value may lie in the information it collects and the decisions that information subsequently enables.

The Bayraktar TB2 belongs to a class of unmanned aircraft designed for intelligence, surveillance and reconnaissance as well as armed missions. Its endurance and electro-optical and infrared capabilities give such a platform the capacity to observe activity over extended periods.

That distinction is crucial.

A reconnaissance mission conducted once may reveal a moment.

Persistent surveillance can reveal a pattern.

And patterns are often more valuable to military planners than isolated images.

A convoy observed on one occasion may simply be a convoy. Repeated observation of the same route may reveal rhythms of movement. Changes in activity may become visible. Unusual concentrations may be noticed. A baseline may gradually be established against which subsequent changes can be measured.

This does not mean that every reported TB2 sortie has such an objective. The specific purpose of individual missions is not publicly known. Nevertheless, the general strategic value of persistent surveillance is well understood.

In the language of modern warfare, the question is not merely whether a platform can shoot.

The question is what it can see, for how long it can see it, and how rapidly the information can be transmitted to those capable of acting upon it.

2. The Bayraktar TB2: More Than a Drone

The Bayraktar TB2 has acquired considerable international recognition through its employment in several conflicts. Its significance, however, should not be exaggerated into mythology. Like every military system, it possesses strengths, limitations and vulnerabilities.

Its importance in the present context lies in the combination of endurance, sensor capability and networked utility.

Such an aircraft can serve as a node within a wider military system comprising ground stations, communications links, intelligence analysts, command headquarters and, potentially, other strike or surveillance assets.

This is why the drone itself should not be examined in isolation.

A modern unmanned aircraft is only the visible part of a larger chain:

Sensor → Communication → Analysis → Command → Decision → Action.

Break the chain at any point and the value of the information may be reduced.

Protect the chain, however, and even a relatively modest platform can become strategically useful.

Recent reporting has also raised questions concerning possible upgrades and satellite communications. Such reports must be handled with caution. Public information does not establish the precise configuration of every aircraft reportedly operated by Pakistan, and it would therefore be improper to assume that every TB2 in Pakistani service possesses identical capabilities.

Nevertheless, the broader trend is unmistakable. Modern unmanned warfare is moving towards greater persistence, longer communication ranges and deeper integration with wider command-and-control networks.

3. The Sixty-Hour Airbridge

Almost simultaneously with the renewed attention upon Pakistani drone capabilities came another development.

Between approximately 19 and 21 August 2026, open-source observers and subsequent media reports identified an unusual concentration of Turkish military transport activity into Pakistan. Turkish C-130 Hercules and Airbus A400M aircraft were reported operating into important Pakistani air bases, including Nur Khan, Masroor and Murid.

Reports also referred to Chinese military transport activity during the same general period.

The significance of such activity lies partly in its timing and partly in its concentration.

Military transport aircraft do not attract strategic attention merely because they fly. Nations conduct military logistics every day. What attracted notice was the apparent density of activity within a relatively short period and the involvement of Pakistan's increasingly important defence partners.

Yet here the analyst must resist the temptation to leap from observation to certainty.

The aircraft movements have been reported. The precise cargo has not been publicly established.

Speculation has included drones, loitering munitions, counter-drone systems, air-defence components and other military equipment. Such possibilities are analytically plausible within the context of Pakistan's existing defence relationships. They are not, however, equivalent to a confirmed cargo manifest.

This distinction is not pedantry.

It is the difference between intelligence and conjecture.

Open-source intelligence can reveal a remarkable amount. Flight paths, aircraft registrations, satellite imagery, airfield activity and logistical patterns may all be studied. But OSINT also has limits. An aircraft can be identified without its cargo being known. A flight can be observed without its ultimate purpose being established.

Thus the correct conclusion is neither that the airlift was meaningless nor that every rumour concerning it is true.

The correct conclusion is that an unusual pattern of military logistics occurred, and its precise purpose remains uncertain.

4. The Emerging Strategic Triangle

The broader context is equally important.

Pakistan's military relationship with China is long established and extensive. Turkey, meanwhile, has emerged as an increasingly significant partner in areas ranging from naval cooperation to unmanned systems and defence technology.

This does not automatically mean that Beijing and Ankara are jointly orchestrating a particular military contingency against India. Such a conclusion would require evidence that is not presently available in the public domain.

Nevertheless, Pakistan's ability to draw military technology, equipment and industrial cooperation from more than one external partner is strategically relevant.

A state recovering from an earlier confrontation does not necessarily rebuild in precisely the same manner in which it fought before.

It may diversify.

It may replenish.

It may study which systems proved vulnerable and which capabilities were insufficient.

It may seek new technologies to compensate for old weaknesses.

In this respect, the growing emphasis upon unmanned systems deserves particular attention. Drones are relatively flexible instruments. They can be employed for reconnaissance, target observation, artillery adjustment, electronic support, strike or deception, depending upon their design and configuration.

The result is a battlefield in which the distinction between intelligence collection and combat operations becomes increasingly blurred.

5. The Veterans' Warning

Over recent days, several retired military personnel and defence commentators have publicly examined these developments. A number of them have expressed the view that Pakistan's present pattern of military activity may indicate preparation for another conflict.

At present, this remains an assessment.

It is not a declaration by an intelligence agency. It is not proof that Pakistan has made a political decision to initiate hostilities. Nor does it establish that war will occur within a particular number of days or months.

But neither should such assessments be casually dismissed.

Military professionals spend decades studying mobilisation, logistics, operational preparation, force posture and the difference between routine activity and unusual military patterns. Their conclusions may differ, and no veteran is infallible. Yet when experienced observers independently begin examining the same collection of developments, their observations deserve to be placed within the wider analytical picture.

One of the central warnings emerging from these discussions is not necessarily that war is certain.

It is that military preparation can begin long before political intentions become publicly visible.

This is a reasonable proposition.

A nation may prepare for several contingencies simultaneously. It may strengthen its forces without intending to fight immediately. Conversely, preparations that initially appear precautionary may later become relevant if the political situation deteriorates.

Preparation is therefore not proof of intent.

But preparation is still preparation.

That is why the present developments warrant study.

6. The Line of Control as a Sensor Battlefield

The Line of Control is traditionally imagined as a physical military frontier: soldiers in fortified positions, artillery behind the front, patrols moving through difficult terrain and observation posts looking across valleys and ridges.

That picture remains real.

But it is no longer complete.

The modern frontier is increasingly layered above the ground.

Above the soldiers may operate:

  • unmanned aerial vehicles;
  • electro-optical and infrared sensors;
  • ground-based radar;
  • counter-UAS systems;
  • electronic warfare equipment;
  • communications networks;
  • airborne surveillance platforms; and
  • space-based assets.
A landscape shaped by successive conflicts: This photograph was taken by me near the Kargil–Skardu Road in the Ladakh region. The surrounding frontier landscape carries the memory of more than one conflict, including military operations during the 1971 war and the 1999 Kargil War. Today, the terrain remains part of the wider strategic environment shaped by the Line of Control, with territory on the far side lying in the region of Gilgit-Baltistan currently under Pakistani administration and claimed by India as part of the former princely State of Jammu and Kashmir. What was once a battlefield defined principally by ridgelines, roads, observation posts and artillery has now become part of a far more complex military environment in which unmanned aircraft, electro-optical sensors, radar, electronic warfare and space-based surveillance increasingly extend the contest far beyond what can be seen from the ground.

A wider view of the same strategic landscape: This photograph, also taken by me near the Kargil–Skardu Road, shows the broader mountainous terrain in which geography, history and military strategy have repeatedly intersected. The landscape that once witnessed conventional military operations and later formed part of the wider theatre of the 1999 Kargil conflict must today also be understood as part of a changing technological environment shaped by surveillance, unmanned systems, sensors and networked warfare.

The terrain has not changed.

The information environment has.

The LoC is therefore becoming not merely a military frontier but a sensor battlefield.

Each side seeks greater awareness of the other's activity while simultaneously attempting to protect its own movements from observation.

This creates a new form of strategic competition.

To see without being seen.

To detect without being deceived.

To understand before the adversary understands.

In such an environment, the destruction of a drone may be less important than understanding the network behind it.

7. The Direct Connection with the Eye Above the Battlefield

The argument developed in the preceding essay concerned India's ability to reduce uncertainty through persistent surveillance and a more integrated intelligence architecture.

The latest reports concerning Pakistani TB2 activity illustrate the reciprocal nature of that challenge.

If one side attempts to see farther, the other must assume that it too is being observed.

If one side seeks to shorten the interval between detection and decision, the other may attempt to do the same.

Thus the contest is not simply between one drone and one missile.

It is between systems.

One system attempts to collect information.

Another attempts to deny, disrupt or deceive that collection.

One system attempts to transform observation into action.

Another attempts to break the chain before action can occur.

The true contest therefore lies within what might be described as the sensor-to-decision cycle.

That brings us back to one of the central propositions of Part III.

The real commodity is time.

But time cannot be purchased without information.

A force that sees an approaching threat earlier has more time to classify it, verify it, decide upon a response and act.

A force that loses situational awareness may discover that the decisive interval has already disappeared.

8. Has the Second Reckoning Already Begun?

Part II considered the possibility of a second reckoning: the prospect that the lessons of an earlier confrontation would not simply disappear but would be studied.

That proposition should now be revisited.

No rational military organisation wishes to repeat an earlier experience without adaptation. If particular methods proved ineffective, alternatives may be sought. If existing surveillance proved inadequate, new systems may be acquired. If an air-defence network requires replenishment, efforts may be made to restore it.

Viewed through that lens, the reported emphasis upon drones, surveillance and military replenishment becomes more intelligible.

It does not prove that a second conflict is imminent.

But it does suggest that the strategic environment has not remained frozen following Operation Sindoor.

The adversary may be learning.

And if the adversary is learning, India must assume that its own previous methods, deployments and responses are being studied as well.

That is not pessimism.

It is the ordinary logic of military competition.

9. The Wider Atmosphere of Regional Uncertainty

Another aspect of the present environment is the increasingly visible concern reflected in international travel advice.

Such advisories must not be misrepresented. A travel warning is not a secret intelligence assessment and cannot be treated as evidence that a war is imminent.

Australia's current advice urges its citizens to reconsider travel to Pakistan overall, while applying higher levels of caution to particular areas. Other governments maintain their own area-specific warnings and restrictions concerning Pakistan and the wider region.

The reasons are not limited to the India–Pakistan equation. Pakistan's western frontier, internal security concerns, terrorism and the conflict environment surrounding Afghanistan also contribute to the overall assessment.

Nevertheless, these advisories provide a useful reminder of a broader reality.

The region is not being viewed internationally as one of uncomplicated strategic tranquillity.

Security risks overlap.

Frontier tensions overlap.

Military developments in one theatre may influence perceptions in another.

South Asia and its adjoining strategic spaces are increasingly interconnected.

10. Why Open-Source Intelligence Matters

There is another lesson in the present episode.

In earlier decades, the public often had little means of observing military activity except through official announcements or conventional journalism.

That world has changed.

Today, aircraft movements may be tracked. Satellite imagery may reveal changes at air bases. Commercial imagery can be compared across time. Public notices, navigation data and photographs can be examined.

Open-source intelligence has therefore become an important supplement to official information.

But it is precisely because OSINT is powerful that it must be handled responsibly.

Observation is not the same as interpretation.

Interpretation is not the same as proof.

A flight path may be genuine while the explanation attached to it is wrong. A satellite image may show activity without revealing the intention behind it. A military aircraft may land at an air base without publicly disclosing what it carried.

The discipline required is therefore simple, though not always easy to maintain:

Observe carefully. Separate fact from inference. Acknowledge uncertainty. Then assess the pattern.

That is the method adopted in this essay.

11. India's Answer Must Be to See the Watcher

The natural public question following reports of hostile or potentially hostile surveillance activity is often: which missile can destroy the drone?

That question is understandable but incomplete.

The first requirement is to know that the platform exists, identify it correctly, understand what it is doing and determine the wider network to which it belongs.

A layered response may involve several elements:

  • ground and airborne sensors;
  • radar and electro-optical detection;
  • electronic warfare;
  • counter-UAS systems;
  • integrated command-and-control networks;
  • air-defence interceptors where appropriate; and
  • space-based and other persistent surveillance assets.

The precise composition of such a system is naturally a matter for the armed forces and the institutions responsible for national security.

From the broader strategic perspective, however, the principle is clear.

India must not merely defend against the weapon. It must understand the system behind the weapon.

A drone is a platform.

The greater challenge may lie in the intelligence architecture that enables it.

12. The Shadow of the Next Conflict

There is, at present, no publicly established evidence that Pakistan has fixed a date for war or taken an irreversible political decision to initiate another conflict with India.

That must be stated plainly.

Yet it would be equally unwise to insist that the developments of recent weeks are meaningless simply because the final intention behind them has not been publicly revealed.

The reported employment of Bayraktar TB2 drones near the Line of Control, the unusual concentration of Turkish military transport activity, reported Chinese military movements, the continuing growth of Pakistan's defence relationships and the warnings expressed by experienced military veterans together form a pattern worthy of serious examination.

What the pattern ultimately signifies remains uncertain.

It may represent replenishment.

It may represent modernisation.

It may represent preparation for several possible contingencies.

Or it may form part of a more deliberate preparation for another confrontation.

At present, none of these possibilities can be declared with certainty.

But uncertainty is not the same thing as irrelevance.

The strategic lesson is therefore not that India should panic.

It is that India should watch.

Watch the aircraft.

Watch the air bases.

Watch the drones.

Watch the networks behind them.

Watch the changing relationships between states.

And, perhaps most importantly, understand that in modern warfare the first contest may begin long before the first shot is fired.

It begins when one side starts to learn.

It deepens when one side begins to watch.

And it becomes dangerous when the other side fails to realise that it is being watched.

The battlefield of the future may therefore not belong simply to the side possessing the greater number of weapons.

It may belong to the side that first understands what the other side is preparing to do.

For in the coming age of warfare, the first advantage may not be the ability to fire first.

It may be the ability to see first.

Note on methodology: This essay distinguishes, as far as publicly available information permits, between reported events, open-source observations, informed military assessments and analytical inference. Where the precise cargo, intent or operational purpose of a military movement has not been publicly established, it is treated as uncertain rather than presented as fact.

About the Author

I am an independent writer with a sustained interest in science, technology, astronomy, history, geopolitics and the manner in which technological change reshapes the world around us.

I do not claim military expertise, nor do I attempt to substitute personal conjecture for professional knowledge. My interest lies in examining publicly available information, comparing developments across time and asking whether apparently separate events may form part of a larger strategic pattern.

Where military veterans and specialists offer assessments based upon professional experience, I believe their observations deserve serious consideration, even when those assessments cannot be treated as confirmed intelligence. The purpose of my writing is therefore not to manufacture certainty where none exists, but to distinguish between what is known, what is reported, what is inferred and what remains uncertain.

In an age in which information travels faster than verification, the discipline of asking careful questions may be as important as the confidence to offer answers.
