Modi Flags Off World's Largest Hydrogen Passenger Train

India launched its first hydrogen-powered passenger train on 17 July 2026, when Prime Minister Narendra Modi flagged off the service from Jind railway station in Haryana. The train runs on the 89-km Jind-Sonipat section of Northern Railway and, with 10 coaches carrying roughly 2,600 passengers, is the largest-capacity hydrogen train in commercial passenger service anywhere in the world.

The milestone places India alongside Germany, France, Japan, and China in the small group of countries operating hydrogen trains. What separates the Indian effort is its ambition at entry. Hydrogen trains in those countries typically run two to four coaches on short regional routes. India started with a full-length passenger trainset, skipping the incremental scaling that other programmes required.

How the train actually works

A hydrogen train carries its own power plant instead of drawing electricity from overhead wires. Hydrogen stored in onboard cylinders reacts with oxygen inside a fuel cell, producing electricity through a chemical process. That electricity drives traction motors identical to those in a conventional electric train. The only emission at the point of use is water vapour. For routes where stringing overhead wires is impractical or too expensive, this technology delivers electric-quality traction without the grid connection.

The trainset runs at 75 km/h on the Jind-Sonipat stretch, with a design ceiling of 110 km/h. Propulsion comes from two power cars generating 1,600 hp each. Safety systems include multi-layer leak, heat, flame, and smoke detection, automatic hydrogen shut-off, and continuous ventilation. A dedicated hydrogen production and refuelling facility at Jind produces hydrogen through electrolysis. Refuelling is faster than charging battery-electric alternatives and operationally closer to how a diesel locomotive is topped up, which matters for tight turnaround schedules in regular passenger service.

The project was built entirely within India. Research Designs and Standards Organisation in Lucknow led design and technical specifications. Integral Coach Factory in Chennai built the coaches. Hyderabad-based Medha Servo Drives handled system integration. Together, they form a rail engineering supply chain that the government can scale without significant dependence on foreign vendors.

Where hydrogen fits inside Indian Railways' green strategy

Indian Railways has already electrified over 99 percent of its Broad Gauge network, one of the fastest electrification programmes undertaken by any major railway system globally. Hydrogen traction is not a replacement for that electrified mainline. Its role is specific: covering routes where overhead electrification is economically or physically impractical, including hilly terrain, remote branch lines, and heritage routes.

The pilot covering the first trainset and its ground infrastructure cost roughly Rs 112 crore. Indian Railways has a broader plan to deploy 35 hydrogen trains at an estimated outlay of Rs 2,800 crore, or approximately Rs 80 crore per trainset and Rs 70 crore per route for supporting infrastructure. That roadmap signals a long-term institutional commitment, not just a one-off demonstration.

A distinct strand of this plan is the Hydrogen for Heritage programme, which has identified iconic lines including the Kalka-Shimla railway as candidates. The initiative would replace steam and diesel locomotives on eight heritage routes, keeping the character of those lines intact while eliminating their emissions. For heritage tourism, that is a meaningful operational shift, not just a symbolic one.

The wider consequence is competitive. If the 35-train programme scales as planned and the heritage deployments follow, India could become one of the largest hydrogen rail operators in the world within this decade. The supply chain already built across Lucknow, Chennai, and Hyderabad gives Indian manufacturers a base to bid on future contracts and potentially export the model. For a country that moved from near-total diesel dependence to 99 percent electrification in a compressed timeframe, hydrogen represents the remaining gap in a fully green national railway, and the Jind service is now the working proof of concept.
