The Chennai Metro, officially Chennai Metro Rail Limited (CMRL), is a rapid transit system serving the city of Chennai , India. The system commenced revenue service in 2015 after partially opening during the first phase of the project, which consists of lines along two corridors covering a length of 45.1 kilometres (28.0 mi).The Government of India approved the plan for a 9 kilometres (5.6 mi) extension in 2016.

Upon completion, the Chennai Metro will be the first metro project in India that will integrate other public transportation systems and the project is expected to reduce the commuting time by 75% from one end of the city to the other. The system would also takeover the existing  Chennai Mass Rapid Transit System , which would be upgraded to operate using the rolling stock of the Chennai Metro.  CMRL was recognised by the International Association of Public Transport in 2011.

The construction began in June 2009 and the first stretch covering the seven stations from Koyambedu to Alandur over a distance of 10 kilometres (6.2 mi), began operation on 29 June 2015.  On 21 September 2016 the section between Chennai airport and Little Mount commenced operation As on 14th Oct 2016, Chennai Metro opened operations on the 1.28km stretch from Alandur to St Thomas Mount, thus making the entire elevated stretch of Green line and also the entire elevated stretch of Chennai Metro Phase I is now functional.
