India's railways just got a greener gear. Union Petroleum Minister Hardeep Singh Puri on Sunday, September 27, 2026, championed the launch of an LNG-based train from Sabarmati, Ahmedabad — framing it as a critical step in India's push to wean its national rail network off diesel and cut crude oil import bills.

Posting in Hindi, Minister Puri wrote: 'रेल की रफ्तार अब Green Energy के साथ!' — 'The speed of the railway, now with green energy!' — crediting Prime Minister Narendra Modi's guidance for steering Indian Railways toward a cleaner, more environment-friendly future, not just a faster and more modern one.

Why LNG, and why Sabarmati

Liquefied Natural Gas (LNG) burns significantly cleaner than diesel, producing lower particulate matter and carbon emissions per unit of energy. For Indian Railways — one of the world's largest rail networks — even a partial shift from diesel traction on non-electrified corridors carries outsized environmental and economic weight. Sabarmati, the Ahmedabad railway hub, serves as a symbolically fitting launchpad: Gujarat has been at the centre of India's city gas distribution expansion and infrastructure push for over a decade.

Minister Puri specifically highlighted two advantages: reducing dependence on diesel — a refined petroleum product heavily tied to crude oil imports — and saving foreign exchange. Every barrel of crude oil India does not import is a direct relief on the current account, a pressure point that policymakers have flagged consistently as global energy prices remain volatile.

Green Rail and the 2030 net-zero target

Indian Railways has committed to achieving net-zero carbon emissions by 2030, a target that rests on two pillars: aggressive electrification of its route network and selective adoption of alternative fuels like LNG on corridors where overhead electrification is not yet viable. The LNG move fits squarely into the second pillar — a bridging strategy that delivers emission cuts without waiting for full electrification.

The Ministry of Petroleum and Natural Gas, which Puri heads, has been actively promoting LNG as a transport fuel beyond just passenger cars and trucking. Testing LNG on heavy-haulage rail — where diesel engines are large and fuel-hungry — represents a logical extension of that mandate, aligning the petroleum ministry's energy-security agenda with the railways ministry's green commitments.

What this means for India's energy transition calculus

India's broader transport decarbonisation strategy has never been a single-fuel bet. Electric traction dominates the long-term plan, but LNG, compressed natural gas, and eventually green hydrogen are positioned as parallel tracks for segments of the fleet that cannot be electrified quickly. The Sabarmati launch, if it expands to other routes, could accelerate the case for dedicated LNG refuelling infrastructure at major rail yards — a supply-chain build-out that would benefit domestic gas distributors and reduce the stranglehold of imported diesel.

The watch now is on whether additional LNG or dual-fuel locomotives roll out on other non-electrified corridors, and how swiftly the refuelling logistics can be standardised across the network. A pilot that stays a pilot changes little. One that scales rewrites the fuel map of Indian Railways.
