The next time you plug your mobile charger into a socket on a train, it might be powered by solar energy. With two solar-powered coaches on the Pathankot-Jogindernagar narrow gauge line set to complete a successful trial run of a year this July, a proposal has been mooted for the experiment to be extended to all coaches on narrow gauge trains in Northern Railway.
The roofs of the coaches are equipped with solar panels. One was developed at Pathankot and the other at Kalka. Fans, lights and electrical points for charging mobiles or laptops on these coaches run on solar energy.
