The Green Line is one of the two operational lines of Chennai Metro apart from the Blue line in the city of Chennai. The line stretches from {{stl|Chennai Metro|Chennai Central}} to {{stl|Chennai Metro|St. Thomas Mount}}, covering a distance of {{cvt|22|km}}. The line consists of 17 stations out of which nine stations are underground and the rest are elevated or on ground level.
Planning for the metro started in 2007-08 with the construction commencing in February 2009. Testing began in 2014, and the Commissioner of Metro Rail Safety approved the operations in January 2015. On 29 June 2015, commercial operations started between Alandur and Koyambedu stations on the green line with the first underground section between Thirumangalam to Nehru Park operational on 14 May 2017, which was later extended to Chennai Central on 25 May 2018.
Planning and construction
In 2006, a modern metro rail system was planned for Chennai modeled after the Delhi Metro.{{cite news|title=Metro is a financial success, not just a technological one|url=https://www.livemint.com/Politics/mcQh3ZfkfIHQ3Q7zkwOQUP/8216Metro-is-a-financial-success-not-just-a-technologica.html|access-date=13 November 2019|newspaper=Livemint|date=11 September 2007|archive-date=13 November 2019|archive-url=https://web.archive.org/web/20191113161153/https://www.livemint.com/Politics/mcQh3ZfkfIHQ3Q7zkwOQUP/8216Metro-is-a-financial-success-not-just-a-technologica.html|url-status=live}}{{cite press release|url=https://chennaimetrorail.org/wp-content/uploads/2015/11/pre2.pdf|title=Chennai Metro Rail Project approved by Government of India|date=28 January 2009|access-date=1 December 2023|publisher=Chennai Metro Rail Limited|archive-date=8 April 2023|archive-url=https://web.archive.org/web/20230408220627/https://chennaimetrorail.org/wp-content/uploads/2015/11/pre2.pdf|url-status=live}} Delhi Metro Rail Corporation (DMRC) was tasked with preparing a detailed project report on the implementation of metro system in Chennai.
