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.
Normally, DEMU trains provide power for its passenger comfort systems – lights and fans – from a diesel driven generator fitted on its Driving Power Car (DPC). IROAF has developed this system with a smart MPPT inverter which optimises power generation on a moving train to cater to full load even during the night. The unique feature of Battery Bank through storage battery ensures sufficient electricity when the sunlight is not available.
Northern Railway launched the first DEMU service on Indian Railways in 1994. Today, NR has 3 DEMU sheds having highest DEMU holding on Indian Railways. Shakurbasti DEMU shed of Northern Railway has been a pioneer in the field of green powered DEMUs – CNG & Solar powered. The very first CNG fitted DEMUs were run by Shakurbasti.
Now the first Solar panel powered DEMU train will also be maintained and operated by DEMU shed, Shakurbasti of Northern Railway. This pioneering effort makes a transition towards clean energy and reduction in the carbon emission.
