Amit Shah Launches India’s First LNG-Diesel Dual-Fuel DEMU Train in Gujarat
27 September 2026
4 min read
Union Home Minister Amit Shah has inaugurated India's first Liquefied Natural Gas (LNG) and diesel dual-fuel DEMU train from Sabarmati railway station in Gujarat. This launch marks a significant milestone in Indian Railways' transition toward cleaner, alternative energy sources to curb carbon emissions.
Key Highlights
- The 8-coach non-AC Diesel Electric Multiple Unit (DEMU) rake was engineered and manufactured by the Chennai-based Integral Coach Factory (ICF).
- Operations and maintenance of the newly introduced dual-fuel rake will be managed exclusively by the Ahmedabad Division of Western Railway (WR).
- The inaugural commercial run connects Sabarmati and Mahesana Junction, traversing an approximate distance of 62 kilometers through regional halts like Jhulasan and Ambliyasan.
- Prior to its commercial flag-off, the converted 1,400 HP Driving Power Cars (DPCs) successfully underwent rigorous field trials exceeding 2,000 kilometers.
- The dual-fuel architecture allows seamless switching between LNG and diesel, effectively slashing particulate matter (PM), nitrogen oxides (NOx), and carbon dioxide (CO₂) emissions.

In-Depth Editorial & Exam Analysis
The introduction of India's maiden Liquefied Natural Gas (LNG) and diesel dual-fuel DEMU train represents a paradigm shift in the national transporter's decarbonization strategy. Indian Railways, being one of the largest consumers of fossil fuels in the country, has been aggressively pursuing electrification and cleaner traction technologies to achieve its ambitious 'Net Zero Carbon Emission by 2030' target. While 100% electrification of broad-gauge routes is progressing rapidly, non-electrified branch lines and suburban sectors necessitate bridging technologies like LNG integration to deliver immediate ecological dividends without requiring massive capital-intensive overhead wire infrastructure right away.
Technologically, the conversion involves retrofitting standard 1,400 Horsepower (HP) Driving Power Cars (DPCs) with specialized cryogenic fuel tanks, gas-admission valves, and electronic control units that seamlessly blend natural gas with diesel inside the combustion chamber. This dual-fuel methodology guarantees operational reliability; locomotives are not rendered stranded due to potential localized shortages of natural gas supply, as they retain the intrinsic capability to automatically default back to centuried diesel propulsion. The deployment by the Western Railway's Ahmedabad Division serves as a pilot proving ground, offering empirical data on fuel efficiency, thermal optimization, and maintenance overheads under actual operating conditions across semi-urban terrain.
From a macroeconomic standpoint, scaling up LNG adoption in railway traction directly mitigates India's heavy fiscal reliance on imported crude oil, aligning closely with domestic energy security objectives. Natural gas burns significantly cleaner than conventional high-speed diesel, registering substantial reductions in greenhouse gases (GHGs) and hazardous sulfur emissions. However, scaling this initiative nationwide requires robust infrastructural expansion, particularly cryogenic refueling stations and supply-chain logistics networks adjacent to major locomotive depots. Overcoming these logistical hurdles will be pivotal in mainstreaming alternative fuel corridors across Indian Railways' sprawling network.
