CMRS Approves Chennai Metro’s Koyambedu – Nehru Park Section

The Commissioner for Metro Rail Safety (CMRS) last week gave its final approval to the Chennai Metro Rail Ltd (CMRL) for starting commercial services on the 8 km Koyambedu – Nehru Park underground section of the 22 km Green Line between St. Thomas Mount and Central Stations. This comes after the CMRS and its team conducted a 2-day visual inspection of the line on April 12 and 13. At this point, it isn’t known whether they gave a blanket approval or a conditional one which would require the CMRL to make technical modifications or complete a part of its infrastructure before beginning services.

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.

This is the 3rd stretch of the line 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. Some nice images and videos from the underground section can be seen here: [Pics] Chennai Metro’s First Underground Section Nearing Completion and [Pics] Chennai Metro’s Nehru Park Station – March 2017.

This section includes 7 stations at Thirumangalam, Anna Nagar Tower, Anna Nagar East, Shenoy Nagar, Pachaiyappa’s College (erst. Aminjikarai), Kilpauk Medical College and Nehru Park:

The 2 day safety inspection was carried out by K A Manoharan from the India Railways’ South Circle based out of Bangalore. His team visually inspected the tracks, tunnels, air-conditioning systems, fire-fighting mechanism and passenger amenities, and was the last step before the Chennai Metro Rail Ltd. can commence commercial operations.

There’s currently some minor finishing works pending on the entry/exit structures leading to/from the underground stations.  The line’s opening now depends on when that work is completed as well as the availability of local & union government officials to attend its opening ceremony, so it could open anytime in the next 5 – 40 days.

Whenever it opens, Chennai will become the 5th city 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.

    I was going along the Poonammalle high road and find that all station entrances have still some good work to be done before they open up the stretch. Looks like a good 1 month before they throw it open for commerical operations.

        So the inauguration of this extension is still tentative , as the stations are still left with final touch up .
        However it really seems to be the work is dragged for long time. And I am surprise to hear this will take
        Another 5-40 days .

    With this line operating at only 15 min intervals from Nehru Park, is there any chance they will trains at higher frequency upto Shenoy Nagar? As per the timetable, the current interval during peak hours is 10 mins and with this extension, I hope they don’t reduce it to 15min.
