    Indian Railways' first solar-powered 1600 HP DEMU (Diesel Electric Multiple Unit) is ready! In line with the vision to use renewable energy, Indian Railways has unveiled a new broad gauge solar-powered train that it says is a "path-breaking" leap towards making trains "greener and more environment friendly". The solar power DEMU train has six trailer coaches and is expected to save about 21,000 litres of diesel and ensure a cost saving of Rs 12 lakh per year. FE Online brings you an extensive preview of the new solar-power train and its features: (Image by Arunava Biswas)

    Going ahead, Indian Railways plans to extend the use of solar energy to its entire rolling stock. There are plans to develop a new technology such as flexi solar panels and lithium ion batteries. Railways also plans to develop a solar-powered train grid for all Mail and Express trains. (Image by Arunava Biswas)

    In 2015, Northern Railways had fitted one coach of the Rewari-Sitapur broad gauge passenger train with solar panels. However, this is the first DEMU broad gauge train, in which all coaches have solar panels, says Railways. Solar panel fitted coaches already run on narrow-gauge trains plying on Pathankot-Jogindernagar route in Kangra Valley section and Kalka-Shimla section. (Image by Arunava Biswas)

    A small step but beginning of New Era on Power saving really a lot of saving on Foreign exchange on the cost of diesel in the times to come. Indian Railways have great potential to further grow on solar power both generating solar power for the nation as it has lot of land to work on Solar power for the nation. The Indian Railways can even be a surplus power generator to cater to the needs of the rural India as well the industries near by its rail tracks around the country. Engineering Division of Indian Rail deserve special compliments.

      Don't trains have dynamo to generate power when train is in motion? They also have batteries to store energy and provide it when train is stationary. Why do you need solar then?
