Indian Railways Green Initiatives: To move closer to its net-zero emission goal, Indian Railways (IR) is rapidly adopting solar energy as part of its strategy towards a greener and more sustainable transport network. As part of the initiatives, Uttar Pradesh’s Varanasi has become the country’s first city to have portable solar panels between railway tracks.
Banaras Locomotive Works (BLW), Varanasi has commissioned India’s first removable solar panel system installed between railway track.
Sharing a post on X (formerly Twitter), Ministry of Railways said: “Banaras Locomotive Works, Varanasi commissioned India’s first 70m removable solar panel system (28 panels, 15KWp) between railway tracks—a step towards green and sustainable rail transport.”
🚆 Indian Railways marks a historic first!

BLW has rolled out this pilot project in its workshop line number 19 with an indigenously-designed installation procedure to lay solar panels between the rails without disrupting train traffic. “These solar panels are not only durable and efficient but also removable allowing for maintenance and seasonal adaptation,” the railways said in a statement.

Indian Railways has track length of 1.2 lakh km. The railways can utilised the yard lines for installation of solar panels between the tracks. “In this scheme, no land acquisition is required as space between tracks are utilized for solar panels. This scheme has potential of 3.50 lakh units/year/KM,” it said in a statement.
