To reduce the air pollution that has become a plague in many cities in India, the Indian Railways has introduced their first train outfitted with rooftop solar panels. The solar panels will completely power fans, lighting, and display systems in the coaches. In the past, a diesel-fueled generator was used to provide electricity on trains. The government expects the move will save them around 5,547 gallons of diesel as well as nine metric tons of carbon dioxide emissions per coach per year.
