This line extends from Chennai International Airport to Wimco Nagar Depot. There are 26 stations in this line, out of which 13 stations are underground and 13 stations are elevated.
The first section of Chennai Metro Line 1 from Koyambedu to Alandur was inaugurated on 29 June 2015. The entire Line 1 became operational on May 14, 2017, following the opening of the final section from Little Mount to the airport.
