Indian Railways Quadrupling Major Rail Corridors to End Delays
Minister Ashwini Vaishnaw announces quadrupling of 7 major rail corridors to add 1,000+ trains and resolve congestion across India.

Union Minister for Railways Ashwini Vaishnaw has announced a massive plan for quadrupling major rail corridors across the country to permanently resolve congestion and train delays. This strategic expansion is designed to boost capacity for both high-volume passenger traffic and the heavy freight movement essential to the economy.
Targeting the Golden Quadrilateral and Diagonal Routes
To create long-term capacity and tackle the persistent problem of long passenger waiting lists, the government has prioritized the four-lining of key national rail routes. These corridors connect the nation's most significant economic hubs and are vital for seamless connectivity.
The Seven Corridors Under Expansion
The expansion projects will focus on the major routes forming the Golden Quadrilateral, alongside critical diagonal corridors:
- The routes connecting Delhi, Kolkata, Chennai, and Mumbai.
- The diagonal corridor from Delhi to Chennai.
- The diagonal corridor from Mumbai to Kolkata.
- The diagonal corridor from Delhi to Guwahati.
Addressing Freight and Passenger Pressure
Minister Vaishnaw highlighted that the rail network is currently facing a period of peak congestion. This is largely driven by the heavy movement of coal and other goods, which, combined with a surge in passenger volumes, has put immense pressure on existing lines.
"We are currently experiencing a period of peak congestion. There is a peak in the movement of coal and other goods. To address this, 36,000 kilometres of additional tracks have been laid over the last 10 years. Constructing new tracks and increasing capacity is crucial; this is the only way to provide a permanent solution," said Ashwini Vaishnaw.
1,000+ New Trains to Boost Availability
The completion of these four-lining projects is expected to be a game-changer for commuters. Once the expansion is finished, Indian Railways will be able to operate over 1,000 additional regular trains. This significant increase in capacity will drastically reduce the pressure on reservation availability and help eliminate the long waiting lists that passengers frequently encounter.
