idea of making railway coach and station on solar energy based is really good. By this general coaches can also be converted in AC coach. Good facility on minimum cost is reflection of best utilization of resources. making railways profitable by increasing fare is only taking advantage of transportation. and the cost public is paying by getting delayed, wasting time on station and train by no reason in delay of train??
