India Plans Solar Power Systems On Roofs Of 500 Trains

Looking to extend the success of a pilot project that saw the roofs of trains covered with solar power systems, the Indian Government is planning to financially support a similar but larger plan.

The Government may provide subsidies to Indian Railways to set up solar power systems atop 500 trains. The systems would be used to power lighting, fans, and air-conditioning systems aboard the trains, while the potential subsidy may be provided through the National Clean Energy Fund, which is replenished through the tax levied on coal mined or imported in India.

This program is in addition to the existing plan to set up 500 MW rooftop solar capacity at railways stations around the country.

Both these plans are expected to bring huge financial savings to Indian Railways, which is probably the single largest consumer of electricity in the country. In 2013-14, Indian Railways consumed 17.5 billion kWh electricity, or about 1.8% of the total electricity generated in India. On top of this, it also has to pay significantly higher tariffs than other consumer categories.

Indian Railways is planning to source 10% of its electricity demand from renewable energy sources by 2020. Last month, it signed an agreement with the Ministry of New & Renewable Energy to set up renewable energy projects, including rooftop projects, utility-scale projects, solar water heating systems, and solar street lighting systems. The Ministry of Railways also announced last year that it would set up 1 GW of solar power capacity over the next 5 years.

Indian Railways is also planning to set up large-scale solar power projects on its unused land, and may open tenders for competitive auctions of the projects to set up these power plants.

I don't think solar energy will be sufficient to run loco's traction motors.

it may be use in combination solar + diesel

i hope use of buildings for installing solar panels is a taken up earnestly. this will be far useful and really help in bringing down some expenses.
as far as suggestion of using solar power for traction, i'm afraid that just not possible. Solar power is too dilute to meet traction requirement that typically runs in order of 1.5-4 Me per loco. in terms of solar power this would require several square meters of panel area and incredibly huge battery bank.
