IR Launched 1st-ever LNG diesel dual-fuel DEMU Train in Ahmedabad 
Indian Railways (IR) successfully launched India’s 1st-ever Liquefied Natural Gas (LNG)-diesel dual-fuel Diesel Electric Multiple Unit (DEMU) train at Sabarmati in Ahmedabad, Gujarat in January 2026.
Key Features:
Dual-fuel System: The Integrated Coaching Depot (ICD), Sabarmati has successfully modified two 1,400 Horse Power (HP) DEMU  Driving Power Cars (DPCs) equipped with 2,200-liter (lt) LNG tank to operate on a dual-fuel system, enabling up to 40% diesel substitution with LNG.
Operational Efficiency: Both modified units have successfully completed more than 2,000 kilometers (kms) of field trials.

• After the successful trials, the train is now capable of covering a maximum 222 km of daily operation on a single  full refill.

Economic Significance: Trial-based estimates indicate an annual savings of nearly Rs 11.9 lakh per DPC and about Rs 23.9 lakh annually for an 8-coach DEMU train.
Environment Impact: The use of LNG will help in reducing the levels of Carbon Dioxide (CO2), Nitrogen Oxides (NOx), and particulate matter.
