CMRL to begin trial run of northern Chennai line

Chennai Metro Rail Limited (CMRL) will start the trial runs of 9 km-long northern Chennai line between December 24 and 26. The CMRL is gearing up to open the stretch in January 2021.

The line from Washermenpet to Wimco Nagar is an extension of phase-1 corridor from Washermenpet to Airport via Anna Salai and has two underground and six elevated stations.

The CMRL will begin by operating a trolley carrying a frame of a metro train to check the schedule of dimensions – the distance between centre of the track and the nearest structure – along the route to ensure no structural obstructions during operation of trains for the trial.

This will be followed by operation of a diesel locomotive to check the alignment after which a metro train will be operated on manual mode.
Finally, the officials will test the signalling system by operating trains on the route every day.

Any issues identified will be rectified before the commissioner of railway safety is invited for inspection and approval for the likely commissioning of the line by January-end, a CMRL official said.

This northern line will link localities like Korukkupet, Tondiarpet, Thiruvottiyur and Wimco Nagar with southern parts of the city via arterial Anna Salai.
