Description
Indian Railways has reached a major milestone in sustainable transportation by introducing the country’s first LNG-Diesel dual-fuel Diesel Electric Multiple Unit (DEMU) train. This initiative represents a significant step towards cutting emissions and fuel costs, supporting India’s broader clean energy objectives.
Pioneering Deployment at Sabarmati
The dual-fuel DEMU has been deployed at Sabarmati in Ahmedabad. The project involved converting the driving power cars of a 1,400-horsepower DEMU train to operate on a dual-fuel system, with Liquefied Natural Gas (LNG) replacing nearly 40% of conventional diesel usage—without affecting performance or reliability.
Successful Trials and Seamless Operations
According to Ved Prakash, Divisional Railway Manager of Ahmedabad, the converted power cars have successfully completed field trials covering over 2,000 kilometres. Following these trials, the train has entered regular passenger service, running smoothly with no technical or operational issues. This demonstrates the practicality of LNG-based propulsion in everyday rail operations.
Environmental and Economic Benefits
The LNG-Diesel dual-fuel system brings multiple advantages. It helps reduce carbon dioxide and nitrogen oxide emissions, improving air quality along railway routes. At the same time, decreased diesel consumption lowers fuel costs, making the system economically viable for large-scale use on non-electrified lines. The successful deployment of the LNG-Diesel DEMU sets a benchmark for eco-friendly innovation in Indian Railways and paves the way for expanding alternative fuel technologies on routes pending electrification, reaffirming the railways’ commitment to sustainable and low-emission transport solutions.
