Jaipur:Come March-end, and 50 rail coaches equipped with solar panels will be rolled out from the North Western Railway (NWR) workshop in Jodhpur.Fitted on the roofs of the coaches, the solar panels will power the tube lights and fans, but only in non-AC coaches.This is the first time that such coaches are being manufactured in such a number. Earlier versions have been on pilot basis.Once these 50 coaches start to run on a regular basis, it is estimated that the railways will reduce 239 tonnes in carbon emission, save 1,000 litres of diesel annually, which amounts to savings of Rs 45 lakh.The cost of fixing these panels is estimated at Rs 2.5 crore. With regular maintenance, the panels can be expected to function for about 15-20 years.”Twelve panels with high capacity have been fitted on each the coaches. These will generate 3.6 kilowatt power during full daylight. However, the requirement to meet the load of CFL and fans is 1.6 kilowatt per coach at a time,” said Anil Singhal, general manager of North Western Railway (NWR). Jodhpur and Delhi, he said, are the two cities where solar-enabled coaches are being produced.
