About Indian Railways and Achievement Of Indian Railways

  • Indian Railways is the backbone of long distance passenger transport in India with a network that spans more than 66030 km, making it the world’s third largest rail network and the fourth largest rail freight carrier.
  • The Railways runs 12,000 trains connecting more than 8000 stations and carrying 23 million passengers, and over 7000 freight trains, carrying 3 million tonnes of freight every day.
  • Indian Railways transports 90% of the total coal moved in the country, supplying 50% of the power in India.
  • Forty nine percent of the routes are electrified with 25 KV AC electric traction while thirty three percent of them are double or multi-tracked.
  • Indian Railways started six pilgrims’ special tourist trains to cover Hindu Pilgrim Centres, Jain Pilgrim Centres and Sikh Pilgrim Centres. More different pilgrim Centres being planned in subsequent phases.
  • In Indian Railways, First ‘Green’ DEMU train introduced on Northern Railway to run between Rewari and Rohtak section.
