Planning and construction

Phase I

In 2006, a modern metro rail system was planned for Chennai modeled after the Delhi Metro.[1][2] Delhi Metro Rail Corporation (DMRC) was tasked with preparing a detailed project report on the implementation of metro system in Chennai.[2] Based on the report, the Government of Tamil Nadu approved the first phase of the project in November 2007.[3] The first phase was planned with two lines covering Template:Cvt with Template:Cvt being underground. The first corridor would connect Washermanpet with Chennai International Airport extending for Template:Cvt with Template:Cvt being underground.[2] In December 2007, Chennai Metro Rail Limited (CMRL) was incorporated and the Government of India gave approval for the project in January 2009.[4][3]

The construction started in June 2009.[5] In August 2010, the contract for supplying rolling stock was awarded to Alstom.[6][7] Test and trial runs happened on the Green line in 2013 and early 2014.[8][9][10] After approvals from RDSO and the Commissioner of Metro Rail Safety, commercial operations started between Alandur and Koyambedu stations on the green line in June 2015.[11][12][13] On 21 September 2016, commercial operations commenced between Airport and Little Mount on the blue line.[14] In May 2018, the blue line was extended between Saidapet and AG-DMS.[15] On 10 February 2019, the underground stretch from AG-DMS to Washermanpet of blue line was opened, completing the first phase of the metro.[16]
