Indian Railways Plans Four-Tracking Seven High-Density Corridors Nationwide
Indian Railways wants to add tracks to seven very busy railway corridors.
Together, these corridors cover nearly 11,000 kilometres.
They carry about 41% of India’s rail traffic, even though they make up only 16% of the network.
The routes connect major cities including Delhi, Mumbai, Chennai, Howrah and Guwahati.
Some sections already have four tracks.
Other sections have been approved or are being built.
Detailed Project Reports are being prepared for some remaining sections.
More tracks could allow more passenger and freight trains to run.
The railway minister said this could reduce delays, speed up journeys and support cleaner, lower-cost freight transport.
Indian Railways plans to four-track seven high-density corridors spanning nearly 11,000 kilometres.

The corridors connect Delhi, Howrah, Chennai, Mumbai and Guwahati through seven major routes.
Four-tracking is already complete on some sections, while others are approved, under construction or undergoing DPR preparation.
Railway Minister Ashwini Vaishnaw said the expansion should reduce congestion, increase train services and enable faster journeys.
