Indian Railways become the world’s largest electrified rail system

Indian Railways has become the world’s largest electrified rail system, completing 100 years of electrification in 2025 and surpassing all other networks globally. Nearly all of India’s 70-thousand route-kilometre broad-gauge network is now powered by electricity. This achievement reflects India’s commitment to sustainability, energy efficiency, and modernization of its transport infrastructure.


🚆 Timeline of Indian Railways Electrification

YearMilestoneDetails
1925First electric trainRan between Bombay VT (now CSMT) and Kurla Harbour Line, using 1.5 kV DC
1930s–40sExpansion in Western GhatsElectrification extended to Igatpuri and Pune to tackle steep gradients
1950sShift to 25 kV AC systemAdopted globally accepted standard for efficiency and scalability
1970s–80sRapid expansionMajor trunk routes electrified, reducing reliance on steam/diesel traction
2000sPolicy pushGovernment emphasized electrification for energy security and reduced imports of diesel
2014–2023Accelerated driveElectrification speed increased to ~6,000 km per year under national mission
2023100% electrification of broad-gauge routesIndian Railways announced completion of electrification across all broad-gauge tracks
2025100 years of electrificationIndia celebrated a century since the first electric train, marking itself as the largest electrified rail network globally

🌍 Global Context

  • Indian Railways operates over 68,000 route km, of which 100% broad-gauge is electrified.
  • This makes it the largest electrified rail network in the world, ahead of countries like China and Russia in terms of route length electrified.
  • Electrification reduces dependence on imported fossil fuels, cuts greenhouse gas emissions, and supports India’s climate commitments.

🔑 Key Facts

  • First electric locomotive: “Sir Leslie Wilson” introduced in 1925.
  • Technology shift: From 1.5 kV DC to 25 kV AC, aligning with global standards.
  • Environmental impact: Electrification expected to save billions of liters of diesel annually and reduce CO₂ emissions significantly.
  • Economic impact: Lower operating costs, faster trains, and improved reliability.
