Government hopes to electrify its entire railway track in the next 4-5 years, railway minister Piyush Goyal said on Thursday, as part of the network's efforts to cut its carbon footprint.
Mr Goyal said currently 55 per cent of the railway network uses electricity while the remainder is on diesel.
He said solar power generation capacity of 20 gigawatts will be installed by 2030 for railways.
