Commuters can expect the city’s first underground metro rail line to be up and running by the first quarter of 2017, as Chennai Metro Rail Limited is gearing up to conduct trial runs in the stretch in January next year with all electrical and electronic systems in place. At present, trains are being tested on the 9km line in manual mode as signal systems are not entirely functional.
Metro rail engineers are racing against time to meet deadlines, as they are now installing signal systems between Shenoy Nagar and Nehru Park, which is part of corridor 2 of phase-1 comprising seven stations. Signal systems will make the entire operation on the railway track automatic. When trial runs begin after the signal systems are installed, several aspects including the train’s response to the signals, its link to the control room and automatic platform screen doors will be tested.
“The installation of signal systems has begun and we are looking at getting it in place before the end of this year,“ an official said. Metro rail has been conducting trial runs between Thirumangalam and Nehru Park since the beginning of October. But tra ins were run in manual mode at a speed of 25kmhr as against the maximum speed of 80kmhr, as the signal system was partially operating. This stretch from Thirumangalam to Shenoy Nagar was ready before construction of the airport line was completed.However, the 9km elevated line from Saidapet ramp to the airport was opened in September 2016 before the underground line, as officials were aware of the issues that may arise during underground in spections. But now that track work is complete and four-car trains are being run up to Nehru Park, officials have decided to open the line stretching to 9km.
