India's first indigenously developed hydrogen-powered train is ready to roll. The Ministry of Railways has approved the operational rollout of a 10-coach hydrogen fuel-cell-based trainset for pilot operations on the Jind-Sonipat section of Northern Railway in Haryana — marking India's formal entry into the small global club of countries operating hydrogen-powered passenger rail technology, alongside Germany, Sweden, Japan and China. Powered by a 1,200-kilowatt (approximately 1,200 horsepower) hydrogen fuel-cell propulsion system that ranks among the most powerful hydrogen rail engines anywhere in the world, the train will operate at speeds of up to 75 kilometres per hour while emitting nothing but water vapour into the atmosphere.

The trainset is the visible centrepiece of Indian Railways' broader green-mobility programme — and the first operational hardware deliverable of the "Hydrogen for Heritage" initiative announced by Union Railway Minister Ashwini Vaishnaw in February 2023, under which 35 indigenous hydrogen trains are planned for deployment on heritage, hilly and non-electrified routes across the Indian rail network over the coming years. The train, designed by the Research Designs and Standards Organisation (RDSO) at Lucknow and manufactured at the Integral Coach Factory (ICF) in Chennai, also represents one of the first major deployable products of India's broader National Green Hydrogen Mission.

What has been approved

The Ministry of Railways' approval covers the 10-coach hydrogen fuel-cell-based trainset for commercial pilot operations on the dedicated Jind-Sonipat section of Northern Railway. The trainset uses Distributed Power Rolling Stock (DPRS) technology — a configuration in which the 1,200 kW total propulsion capacity is distributed across the coaches rather than concentrated in a single locomotive, providing more balanced traction and acceleration characteristics. Each carriage is equipped with 100-kilowatt-class fuel cells that convert hydrogen and oxygen into electricity through an electrochemical reaction, with water vapour as the only by-product.

The approval follows a multi-stage clearance process. The Research Designs and Standards Organisation (RDSO) granted technical clearance based on the trainset's design and laboratory performance. The Commissioner of Railway Safety conducted independent safety audits. The Petroleum and Explosives Safety Organisation (PESO) issued the required licence for storage and dispensing of compressed hydrogen gas at the Jind facility. Germany's TÜV SÜD — one of the world's most respected technical inspection and certification bodies — has been appointed as the third-party safety auditor, ensuring that the project meets international standards alongside Indian regulatory requirements.

For the first three months of operations, trained technical staff will accompany the train on every run to address any technical issues that may arise during pilot operations. Maintenance will be carried out at the Shakur Basti yard in Delhi, with the train towed there by a diesel locomotive between maintenance windows in keeping with established safety protocols.

Why the Jind-Sonipat route was chosen

The Jind-Sonipat corridor in Haryana — a 90-kilometre secondary route with moderate traffic — was selected as the pilot venue for several considered reasons. The route provides sufficient operational diversity to gather meaningful performance data across different traffic conditions, while keeping the pilot away from critical primary routes that serve major metropolitan areas. The Haryana climate provides authentic test conditions: summer temperatures regularly exceed 45 degrees Celsius, seasonal dust storms are common, and humidity ranges across the year span the substantial variations that any Indian rail propulsion system must accommodate.

The route also has the operational density to generate meaningful performance metrics — enough trains per day to validate the trainset's behaviour in real-world conditions, but not so high that performance issues during the pilot phase would compromise broader passenger movement. Indian Railways' data collection phase typically extends 12 to 18 months, during which every parameter — energy efficiency, refuelling cycle reliability, hydrogen consumption per kilometre, fuel cell degradation patterns, water vapour emission characteristics, brake and traction performance, and overall passenger experience — will be methodically documented.

The Jind hydrogen facility

The hydrogen production and refuelling infrastructure at Jind is itself a substantial engineering achievement and a critical enabler for the train's operations. The facility includes a 1-megawatt Polymer Electrolyte Membrane (PEM) electrolyser, which splits water into hydrogen and oxygen using electricity. The electrolyser is designed to produce approximately 430 kilograms of green hydrogen per day — sufficient to support the pilot train's operational requirements while leaving margin for expansion.

The hydrogen storage system at Jind has a capacity of 3,000 kilograms — enabling sustained operations even during periods of higher demand or temporary production interruptions. A high-pressure compressor enables rapid refuelling of the trainset, and a standby compressor unit ensures redundancy. Hydrogen leak detectors and flame detectors are installed throughout the production, storage, and dispensing facility, with regular inspection schedules to ensure continued safe operation. The hydrogen produced meets ISO 14687 purity standards — the international specification for hydrogen fuel suitable for fuel cell applications.

Importantly, the hydrogen produced at Jind qualifies as "green hydrogen" — produced through the electrolysis of water using renewable electricity, rather than the "grey" hydrogen produced from natural gas reforming that dominates global hydrogen production today. The green character of the hydrogen is what makes the train's environmental credentials genuinely complete: the upstream production and the downstream operation are both zero-emission.

How a hydrogen train actually works

The basic engineering of a hydrogen train is both elegant and substantially different from either diesel or conventional electric rail propulsion. Onboard hydrogen tanks store compressed hydrogen gas. A fuel cell — essentially an electrochemical reactor — combines this hydrogen with oxygen from the air. The reaction produces electricity (which drives the traction motors), heat (which is dissipated), and water vapour (the only emission). The electricity generated can either drive the motors directly or be stored in onboard batteries for use during peak power demand.

The advantages of this architecture over conventional propulsion are several. Compared to diesel: zero tailpipe emissions, dramatically reduced operational noise (fuel cells have far fewer moving parts than internal combustion engines), and elimination of dependence on imported petroleum products. Compared to fully electrified rail: no need for the substantial capital investment in overhead electrification (the catenary system, the supporting infrastructure, the substations), making hydrogen particularly suitable for routes where electrification would be economically inefficient — hilly terrain, low-traffic secondary routes, and heritage corridors with infrastructure constraints.

The Indian engineering of the 1,200 kW system is itself a substantive achievement. Most operational hydrogen passenger trains globally have used fuel cells in the 500 to 600 horsepower range. India's 1,200 horsepower configuration — achieved through the distributed-fuel-cell architecture of the DPRS design — represents a substantially higher power density than has been deployed elsewhere. The technology has been developed indigenously by RDSO Lucknow.

The "Hydrogen for Heritage" programme

The Jind-Sonipat trainset is the first deployable hardware under the broader "Hydrogen for Heritage" initiative announced by Railway Minister Ashwini Vaishnaw in February 2023. The programme envisions 35 hydrogen-powered trains being deployed on selected heritage routes and hilly corridors where conventional electrification would be expensive, slow to build, or visually intrusive on routes with heritage character.

Among the routes identified for the heritage programme are some of India's most scenic and historically significant lines — including the Kalka-Shimla, Darjeeling Himalayan Railway, Nilgiri Mountain Railway, and Matheran Hill Railway routes, all of which carry UNESCO World Heritage status or substantial heritage value. Hydrogen trains on these routes would preserve their character — no overhead wires, no diesel smoke — while substantially reducing their environmental footprint. The Union Budget 2023-24 allocated approximately Rs 2,800 crore for the development of 35 hydrogen trains, with an additional Rs 600 crore for hydrogen energy infrastructure. The estimated cost per train is Rs 80 crore; the estimated infrastructure cost per route is Rs 70 crore.

The wider National Green Hydrogen Mission

The hydrogen train programme sits within the wider National Green Hydrogen Mission, approved by the Union Cabinet on 4 January 2023. The Mission targets the production of 5 million metric tonnes (MMT) of green hydrogen annually by 2030, with a financial outlay of approximately Rs 19,744 crore. The Mission's strategic objectives include making India a global hub for the production, use and export of green hydrogen; decarbonising hard-to-abate sectors including steel, cement, fertilisers, refineries, shipping and heavy transport; reducing crude oil and natural gas import dependence; and creating skilled employment across the green-energy value chain.

The Mission's principal instruments include the Strategic Interventions for Green Hydrogen Transition (SIGHT) programme, which provides Production-Linked Incentives to electrolyser manufacturers and green hydrogen producers; the Pilot Projects for Niche Sectors framework, which funds demonstration deployments including the hydrogen train pilot; and the Hydrogen Hub framework, which is supporting the development of geographically concentrated production-and-consumption clusters across India. The Mission is implemented by the Ministry of New and Renewable Energy in coordination with the Ministry of Railways, the Ministry of Petroleum and Natural Gas, the Ministry of Heavy Industries, and other line ministries.

Indian Railways' broader green transformation

The hydrogen train arrives at a moment when Indian Railways has substantially advanced its broader green-mobility programme. Approximately 98 per cent of the broad-gauge railway network is now electrified — a remarkable transformation from approximately 20 per cent electrification a decade ago. In the past ten years, approximately 45,000 kilometres of broad-gauge track have been electrified, dramatically reducing the railway system's diesel consumption and emissions footprint.

Indian Railways has also been progressively integrating renewable energy into its operations. The system now operates with approximately 756 megawatts of renewable energy capacity — including 553 MW solar, 103 MW wind, and 100 MW hybrid installations. The railway has set the ambitious target of becoming a net-zero carbon emitter by 2030 — 20 years ahead of India's national net-zero target of 2070. The combination of electrification, renewable energy integration, and hydrogen-powered operations on residual non-electrified routes provides the architecture for achieving this target.

India in the global hydrogen rail club

With the Jind-Sonipat approval, India joins a small group of countries operating hydrogen-powered passenger rail technology. Germany pioneered the technology with the Alstom Coradia iLint — the world's first hydrogen passenger train, which began commercial operations in Lower Saxony in 2018. Sweden, Japan, China, France and the United States have all developed or trialled hydrogen rail technologies.

India's distinctive contribution to this global club is in three respects. First, the indigenous development of the technology — RDSO-designed, ICF-manufactured, with Indian engineering across the propulsion architecture. Second, the high power output — at 1,200 horsepower, the Indian trainset is among the most powerful hydrogen trains anywhere in the world. Third, the scale of the planned deployment — at 35 trains under the Hydrogen for Heritage programme, India is planning one of the larger national hydrogen rail fleets globally.

What it means for India

For Indian Railways, the hydrogen train represents the closing chapter in the country's rail-decarbonisation arc. With near-complete electrification of the broad-gauge network and hydrogen-powered operations on non-electrified residual routes, the entire passenger and freight rail system can move toward zero-emission operations within the current decade. This is significant because Indian Railways currently transports approximately 1.1 billion passengers and approximately 1.5 billion tonnes of freight annually — making it one of the largest single transport systems globally.

For India's energy security, hydrogen-powered rail provides an additional pillar of fuel-source diversification. India currently imports approximately 85 per cent of its crude oil requirements; substituting diesel-powered rail operations with domestically produced green hydrogen reduces the country's exposure to global oil price volatility and supply disruptions. As the National Green Hydrogen Mission scales toward its 5 MMT annual production target, the domestic hydrogen economy will progressively reduce India's overall fossil-fuel import dependence.

For India's industrial ecosystem, the hydrogen train deployment is a substantive demand signal that will drive investment across the broader hydrogen value chain — electrolyser manufacturing, fuel cell production, high-pressure hydrogen storage, refuelling infrastructure, and the supporting engineering services. The combination of policy support (National Green Hydrogen Mission), demand pull (Hydrogen for Heritage rail programme, supplementary deployments in shipping and heavy industry), and Production-Linked Incentives is expected to catalyse a substantial domestic green-hydrogen industry over the coming decade.

For India's global standing in green technology, the trainset's deployment positions the country as a credible exporter of hydrogen rail technology in the coming years. The 1,200 kW power capability, the indigenous engineering, and the demonstrated ability to deploy at scale (the 35-train Hydrogen for Heritage programme) together create the foundation for India to position itself as a hydrogen-rail technology supplier to other emerging economies with similar requirements.

The road ahead

Pilot operations on the Jind-Sonipat corridor are positioned to commence within the second half of 2026, with preliminary operational data expected by mid-2027. The 12-to-18-month data collection phase will inform the subsequent rollout of the remaining 34 trains under the Hydrogen for Heritage programme, with deployment to heritage and hilly corridors expected to begin progressively from 2027 onward.

In the medium term, additional applications beyond the heritage programme are under active study. Suburban routes around major metropolitan areas that are not yet electrified, freight corridors on non-electrified branch lines, and specialised industrial routes are all potential candidates for hydrogen-powered operations. The Ministry of Railways has indicated that successful operation on the Jind-Sonipat corridor will inform broader deployment decisions.

In the longer term, the prospect of Indian-designed, Indian-manufactured hydrogen trains being exported to other countries — particularly emerging economies with significant non-electrified rail networks and growing climate commitments — represents a substantive export opportunity. As global rail networks progressively decarbonise over the coming decades, the demand for hydrogen rail technology will grow substantially, and India's early positioning gives it an advantage.

For now, on the morning of 22 June 2026, what stands on the operational record is this: India's first indigenous hydrogen train — designed by RDSO Lucknow, manufactured at ICF Chennai, with fuel cells indigenously developed and the green hydrogen produced domestically at Jind — is ready to enter service. Indian Railways has formally entered the hydrogen era. The trainset is a tangible expression of India's Aatmanirbhar Bharat capability in advanced green-mobility technology, the deliverable hardware of the Hydrogen for Heritage initiative, and a building block in the broader green-energy transformation that places India among the global leaders in the journey to net-zero rail transport.
