As part of green energy initiatives of the Southern Railway, a coach powered by solar roof panels was operated on a trial basis in Salem. The trail run was successful and the ‘Go Green coach’ would soon be attached to Coimbatore – Mayiladuthurai Jan Shatabdi express. This is south India’s first solar panel fitted coach. The solar panels would power 35 lights and 24 fans of the coach. This would help the railway save 1700 litres of diesel per annum per coach. The cost of installing the solar panels works out to Rs7 lakh per coach, but the Salem based company – Ind Aussie Solar Private Limited – which supplied the panels, will charge the railways Rs3lakh per coach only, to promote the initative. Before going ahead with the green intiative, the existing conventional lights in the coaches need to be changed to LED lights. According to southern railways’ assessment, carbon footage would be reduced by 4.5 tonnes per coach per annum if they are powered by solar panels. The solar panels have been mounted on a specially designed metallic structure to withstand high wind velocity, vibration and shock during train movement.
