Union Urban Development Secretary and Chairman of Chennai Metro Rail Limited (CMRL), M. Ramachandran, on Friday met Tamil Nadu Chief Minister M. Karunanidhi and discussed the progress of the Rs. 14,600 crore project.

Talking to reporters, Mr. Ramachandran said Prime Minister Manmohan Singh was invited for the formal launch of the project.

The project, whose cost will be shared equally by the Central and state governments, was expected to be completed by 2015 on a 45 km route in the city, with about 24 km of the route planned underground, he said.

To make sure that the venture was a profitable one, the CMRL had requested Tamil Nadu government to earmark land to develop commercial spaces along the route of Metro Rail, Mr. Ramachandran said.

A committee could decide on the fare structure for the CMRL, like a three-member committee did for Delhi Metro, he said.

The Chennai Metro Rail is scheduled to be implemented in two corridors—Washermanpet to Chennai Airport and Chennai Central to St Thomas Mount on the southern side of the city.
