Power requirement of railway is 1650 MW. As per data ref:- Ministry of statistics & programme implementation, statistical book India 2014 table 16.10- 2 . Indian Railway has length of about 64500 route km. Considering 3 meter. Width on both sides of track, the available area is 87000 acers. Area required for generation of power based on solar energy is 6.5 acers per MW. . Only half of the total area may be useful for solar power generation, & with this available area 6500 MW. Power can be generated. Indian railway can fullfill own power need, & supply surplus power to other utilities. Land acquisition is a difficult task; many projects are delayed due to this reason. Incidentally Indian Railway has got land already acquired, & can be used for power generation based on solar energy. more
