Three major rail routes linking Chennai to be expanded to four tracks

CHENNAI: Three major rail routes linking Chennai with Howrah, Mumbai and Delhi are among seven high-density rail corridors being expanded to four tracks to meet growing passenger and freight traffic.

The seven corridors, together stretching about 11,000 km, handle around 41% of Indian Railways’ total traffic, despite accounting for only about 16% of its rail network, Railway Minister Ashwini Vaishnaw said.

The three corridors involving Chennai are Howrah–Chennai, Chennai–Mumbai and Delhi–Chennai. The other corridors are Delhi–Howrah, Mumbai–Delhi, Mumbai–Howrah and Delhi–Guwahati.
