India’s First LNG-Based Dual-Fuel DEMU To Launch From Sabarmati On September 27

India’s first LNG-based dual-fuel DEMU will be launched from Sabarmati station on September 27, with the train set to operate between Sabarmati and Patan.

The train has been developed as part of Indian Railways’ efforts to reduce diesel consumption, fuel costs and emissions through alternative-fuel technology.

LNG To Replace Up To 40% Of Diesel

At the Integrated Coaching Depot in Sabarmati, the Driving Power Cars (DPCs) of two 1,400 HP DEMUs have been converted to a diesel-LNG dual-fuel system.

The technology allows LNG to replace up to around 40% of diesel consumption, according to the details provided for the project.

Both DPCs have completed field trials covering more than 2,000 km. Following the trials, the dual-fuel technology is now being introduced into regular railway operations.

Up To ₹ 23.9 Lakh Annual Fuel Savings

The dual-fuel system is expected to lower diesel consumption and reduce operating costs.

Testing data indicates estimated annual savings of around ₹ 11.9 lakh for each DPC. For an eight-coach DEMU rake, the projected annual saving is around ₹ 23.9 lakh.

The DEMU currently operates on routes connecting Sabarmati with Mehsana, Palanpur and Abu Road.

Lower Emissions Expected

The use of LNG is also expected to reduce emissions from DEMU operations.

According to the project details, replacing part of the diesel consumption with LNG can help lower emissions of carbon dioxide, nitrogen oxides and particulate matter.

The initiative is also aimed at expanding the use of alternative fuels in railway operations and reducing dependence on diesel.

Speed Trials Reached 222 Kmph

The LNG dual-fuel DEMU has undergone technical and performance testing, including high-speed trials.

The train reportedly reached speeds of up to 222 kmph during testing. The trials assessed the performance and safety of the dual-fuel system under operating conditions.

Sabarmati-Patna Service To Follow Launch

The first LNG-based dual-fuel DEMU is scheduled to be formally launched at Sabarmati station on September 27.

The train will operate between Sabarmati and Patan, marking the start of regular operations for the technology after more than 2,000 km of field trials.
