The Chennai Metro Rail Ltd. (CMRL) is all set to inaugurate commercial services on the 8 km Koyambedu – Nehru Park underground section of the 22 km Green Line on May 14th (Sunday) with top state ministers and the Union Minister for Urban Development accepting their invite to attend the launch ceremony.
This section is Chennai’s 4th stretch overall and the 3rd stretch of the Green Line, between St. Thomas Mount – Central, to get ready after the Koyambedu – Alandur section opened on 29 Jun 2015 and Alandur – St. Thomas Mount section on October 14 2016. The CMRL started trial runs between Koyambedu & Anna Nagar East stations in April 2016, extended them to Shenoy Nagar in July 2016 and then to Nehru Park in October 2016. The line was approved by the CMRS in mid-April after a 2-day inspection on April 12-13.
For commercial operations, the CMRL plans to utilize both tunnels between Koyambedu – Shenoy Nagar and only the down-line tunnel between Shenoy Nagar – Nehru Park, as the Nehru Park station lacks a train reversal facility. Due to this, it will maintain a 15 minute frequency in the underground stretch until the Nehru Park – Central Station section opens up in 2018.
Although the Airport – Little Mount section of the Blue Line consists of a small 600m underground section near the airport’s secondary runway, the Koyambedu – Nehru Park stretch will be the city’s first true underground metro line to open up connecting 7 underground stations at Thirumangalam, Anna Nagar Tower, Anna Nagar East, Shenoy Nagar, Pachaiyappa’s College (erst. Aminjikarai), Kilpauk Medical College and Nehru Park – each featuring platform screen doors:
This section was built by two contractors:
• UAA-05: Thirumangalam Ramp – Shenoy Nagar by Afcons-Transtonnelstroy JV
• UAA-04: Shenoy Nagar – Egmore by L&T-SUCG JV

Once inaugurated, Chennai will become the 5th city in India to operate an underground metro line after Kolkata, Delhi, Jaipur and Bangalore. Its network’s length will become 27.9 km long – just shy of Kolkata Metro’s 28.14 km Line-1.
Stay tuned for a post on its inauguration!
