What This Article Covers

1.Indian Railways launched its first LNG-diesel dual-fuel train from Sabarmati on September 27, 2026, built by ICF Chennai.

2.The system replaces ~40% of diesel with LNG, offering fuel flexibility, lower emissions, and estimated savings of ₹23.9 lakh per 8-coach rake annually.

3.Unlike the hydrogen train (fuel-cell based, zero tailpipe emissions), the LNG train uses a modified internal-combustion engine and is not a completely green alternative.

The Big Picture
