Indian Railways launches first LNG-diesel hybrid train
Indian Railways has launched its first **LNG-diesel hybrid train**, marking a significant step toward sustainable rail transport. The eight-car trainset completed its inaugural run on the 63 km Sabarmati, Mahesana line on 27 September. Since January, the train has been undergoing trial operations with passengers in western India.
The dual-fuel system, installed on two DEMU power cars, combines liquefied natural gas (LNG) and diesel. Each power car is equipped with a 2,200-litre cryogenic tank to store LNG. This setup allows up to 40% of diesel consumption to be replaced with LNG, which is injected into the cylinders alongside diesel.
With full tanks, the train can travel up to 444 km in dual-fuel mode. The system automatically switches to diesel when the LNG is depleted. Indian Railways estimates annual fuel savings of around INR 2.4 million (USD 28,000) per trainset, with similar reductions in maintenance costs.
Looking ahead, the national operator plans to convert eight more DEMU power cars to dual-fuel traction, enabling the deployment of four additional LNG-diesel trainsets.
