CHENNAI: If you thought the 42 trains running along metro phase-1 were impressive, wait for phase-2. The second phase, officials said, is likely to have more than 85 trains across three corridors adding up to 107.55km. Metro rail will build two additional depots, one each at Madhavaram and Siruseri, to maintain the fleet.
“Going by the train frequency of two-and-a-half minutes planned for phase-1, we needed 42 trains. If you go by the same calculation, phase-2 will need more than double that number of trains to cover the three corridors,” said a metro rail official.
The official said several factors like headway, length of a corridor and the number of stations along the route will be considered before deciding the exact number of trains required to operate. Phase-1 has 32 stations along 45km, while phase-2 will have 116 stations covering 107.55km. It means the average distance between two stations could be less than a kilometre. Metro rail is procuring 10 more trains to operate the 9.051km phase-1 extension connecting north Chennai through eight stations.
