Indian Railways has hit a significant milestone by rolling out the country’s very first LNG–Diesel dual-fuel DEMU train. This exciting development has been launched at Sabarmati in Ahmedabad, representing a major step towards more sustainable and eco-friendly rail operations.
This initiative aligns perfectly with Indian Railways’ mission to cut down on pollution, lower fuel expenses, and embrace cleaner energy alternatives.
What Is an LNG–Diesel Dual-Fuel DEMU Train?
A DEMU (Diesel Electric Multiple Unit) train is typically used for short-distance passenger travel. In this innovative model, the DEMU train has been enhanced to operate on a dual-fuel system, utilizing both Liquefied Natural Gas (LNG) and diesel.
The train boasts 1,400 horsepower (HP) driving power cars that have been modified to run on LNG in addition to diesel. By replacing about 40% of traditional diesel with LNG, this train becomes not only more fuel-efficient but also cleaner for the environment.
Key Features & Performance Engine & Fuel System:
The project involved retrofitting two 1,400 HP Diesel Electric Multiple Unit (DEMU) power cars with approximately 2,200-litre LNG tanks.Dual-Fuel Efficiency: The system replaces nearly 40% of conventional diesel consumption with Liquefied Natural Gas (LNG).
Range: A single full tank enables the train to cover up to 2,200 kilometres, offering high flexibility for regional passenger services.
Seamless Switching: The engine can automatically switch between LNG and diesel depending on availability, maintaining the same power and reliability as traditional engines.
Environmental & Economic Impact Emission Reductions:
The train significantly lowers carbon dioxide, nitrogen oxide, and particulate matter emissions, improving air quality along its routes.Cost Savings: Indian Railways estimates annual savings of approximately ₹11.9 lakh per power car. For a full 8-coach DEMU rake with two power cars, savings could reach ₹23.9 lakh per year.
