Thirumayilai metro station is a Metro railway station on the Orange Line of the Chennai Metro. The station is among the underground stations along corridor I of the Chennai Metro, Lighthouse–Poonamallee Bypass stretch. The station serves the neighbourhoods of Mylapore.

The station is a key interchange linking Corridor 3 and Corridor 4 of the Chennai Metro network and, at 115 ft below the ground, will be the deepest metro station in Chennai.

History

Construction began in 2023 and the station remained an engineering challenge during its construction owing to its depth cut through rocky soil. Owing to these difficulties, the station is expected to be completed by 2028.[1]

Construction

The T-shaped station will be built on four levels with four tunnels stacked one above the other, below the Luz Junction (junction connecting Luz and the Canal Bank Road) in the neighbourhood of Mylapore.[1] Upon construction, the station will be the deepest metro station in Chennai, at 35 meters below street level, surpassing the Chennai Central metro station, which is 30 meters below street level.[1] This is because the rails in corridor 3 run as stacked tunnels, with one track located 17 metres below the ground (first level, or platform 1) and another 35 metres below (third level, or platform 3). The tracks in corridor 4 will be in parallel tunnels (second level, or platform 2) built between platforms 1 and 3.[2]

The station

The station will be located at a depth of 35 metres (115 ft) below the ground with four levels, namely, a concourse level and three platform levels.[3] The first (uppermost) level will be at a depth of 17 metres (56 ft) consisting of the Madhavaram–SIPCOT upper track. The middle level will be at a depth of 24 metres (79 ft) and will consist of the Lighthouse–Poonamallee dual lines. The third (lowermost) level will be at a depth of 35 metres (115 ft) consisting of the Madhavaram–SIPCOT lower track.[3] The station will be spread over an area of 4854.4 square meters. While most other stations in phase II has only two entry/exit points, the Thirumayilai station alone will have five entry/exit points.[2]
