The first trial run between Little Mount and AG-DMS underground on Anna Salai began on Thursday , as Chennai Metro Rail Limited(CMRL) is gearing up to run metro trains along the city’s arterial road.
The work on the stretch between AG-DMS and Saidapet is nearing completion. It is part of the airportCentral-Washermenpet line of which Little Mount-Washermenpet stretch is yet to be opened.
While officials earlier planned to open the entire Anna Salai stretch at one go by mid-2018, the beginning of trial runs indicates that it may be opened much before the deadline.Officials said a locomotive was operated on the 4km line from Little Mount and AG-DMS.Round the clock work is underway on the up-line. While the line between AGDMS and Saidapet is underground, Saidapet connects to Little Mount elevated station through a ramp built across the Adyar river.
“Subsequent trial runs with metro trains on the stretch will start after the completion of system works,” a release from CMRL said.
Installation of various critical systems like tunnel ventilation, heating ventilation and air-conditioning system (HVAC), signaling, platform screen doors, automatic fare collection (AFC) gates are complete. Last leg of work is underway at the AG-DMS, Tey nampet, Nandanam and Saidapet stations.
Now, while the line between AGDMS and Saidapet is ready , tunneling is still underway between May Day Park and AG-DMS. Tunnel boring machines are excavating soil and building tunnels near the Anna flyover close to AGDMS station. Officials are expecting to complete tunneling in the next couple of months.
