Times of India reported that as the construction of the 9km metro rail corridor in North Chennai is progressing in full swing, Chennai Metro Rail Limited (CMRL) has started preliminary work to lay ballastless tracks required for the operation of metro trains. The 9km Phase 1 extension line between Washermenpet and Wimco Nagar is expected to be ready by March 2020. A metro rail official said that “We have floated tenders for both MEP (mechanical, electrical and plumbing) and for track work. We are expecting to start track work before the end of this year.”
The extension line in North Chennai includes a 2km underground section connected by two stations and a 7km elevated stretch linked through six stations. Once the line is ready, commuters from north Chennai can travel to several localities in the city that are connected by metro rail network.
Work for the extension line in north Chennai was launched in 2016. Towards the end of 2017, construction of two tunnels along a 2km stretch from Washermenpet to Korukkupet was completed. Soon after, work began for construction of the elevated corridor and is still under way.
