Chennai Metro - Stations

Stations

A total of 32 stations have been planned along the two lines. As many as 19 stations are underground and 12 are elevated. Of these, the Chennai Central (underground) and Alandur (elevated) are common for both the corridors and serve as interchange stations.

All metro stations are being constructed as disabled friendly and elderly friendly, with automatic fare collection system, automatic announcement system, electronic information display boards, escalators, lifts, and toilets. Elevated stations will have shopping malls and parking space, with additional space for future growth. Wi-Fi facility is also being planned at some of the stations. Underground stations will be air-conditioned and will have boosters to amp up cellphone signals within the premises.

Underground stations will have two levels, namely, a platform level and a concourse level. A mezzazine (additional level) in between the two has been planned where the depth of the station is greater. Platform level of the stations will have space for the commuters to assemble during normal operations, delays and emergency situation. The concourse level will be divided into paid and unpaid area and will also house an automatic fare collection system. The unpaid area provides the commuters with facilities such as access to the station, travel information and tickets counters. Automatic ticket gates with scanners provide access to the platforms, which is a common feature at underground and elevated stations.

The elevated stations will have three levels, namely, street, concourse and platform. Street level of the stations will have entry and exit, service rooms for diesel generators and transformers. Concourse level of the stations will be over 5.65 metres above the street level and will have station control room, ticketing counters, ticket gates. The platform for boarding trains will be around 12.6 meters above the street level.

Of the stations, Chennai Central, spread over 70,000 sq m, will be the largest, followed by St. Thomas Mount, Shenoy Nagar, Gemini and Washermenpet. SIDCO station in Guindy will be the smallest. The Chennai Central metro station is being constructed at a depth of 25 metres and will serve as a nerve centre since the both the corridors of the Metro Rail project converge in the station. St. Thomas Mount station, where MRTS and suburban lines meet, will be the second largest metro station in the city, where metro line and MRTS line will meet at two levels. A separate pathway is being provided for commuters from suburban railway station to walk into the Metro-MRTS station complex.

Parking facilities will be available only in some of the stations, including Chennai Central, Chennai Airport, Alandur, and Washermenpet, while others may not have parking provision due to lack of space.
