Chennai Metro

The Chennai Metro Rail is a rapid transit system under construction in Chennai, Tamil Nadu, India. Phase I of the project, which consists of two corridors covering a length of 45.1 km is under construction. The elevated section of the project is scheduled to be operational by mid 2014 and the entire project is scheduled to be completed by the financial year 2014–2015. About 55% of the corridors in Phase I are underground and the remaining corridors are elevated.

Upon completion, Chennai Metro Rail would be the first metro project in the country that will integrate other public transportation systems. The project is expected to reduce the commuting time by 75 per cent from one end of the city to another.


After the success of the Delhi Metro, a similar system has been planned for the city of Chennai by E. Sreedharan of the DMRC to the then Chief Minister of Tamil NaduKarunanidhi. The plan was later dropped in favour of a highly ambitious monorail network, spread over the whole city during Jayalalitha’s tenure. Karunanidhi revived the metro rail project to life once again by including it in the 2007–08 State Government’s budget, and an amount of Indian Rupee symbol.svg 500 million had been sanctioned for preliminary works which included a Detailed Project Report (DPR) to be prepared by the DMRC Rail Project. The approval for the project was finally given by the state cabinet on 7 November 2007 and is to be executed by a special purpose vehicle, the Chennai Metro Rail Limited (CMRL).

Seven lines have been planned by the DMRC for the Chennai Metro network. Two routes are under construction as part of the first phase, with several planned for future phases of the metro network.
