Chennai Metro Rail gets 24 new Train Sets from Alstom, begins testing.
Chennai Metro Rail’s plans to open new routes between Saidapet and Airport, and Thirumangalam and Shenoy Nagar by year-end are on schedule with CMRL having begun tests on 24 new trains that have arrived from Alstom factory in Sri City, Andhra Pradesh.
Last year, metro rail received nine trains imported from Alstom factory in Brazil. They were issued completion certificates and seven were accepted by CMRL in June 2015 when the Alandur-Koyambedu elevated line was thrown open to the public.
Apart from the trains currently in operation, all other trains delivered are under various stages of testing and commissioning at the CMRL depot in Koyambedu.
The stainless steel trains – composed of four cars each – will feature air-conditioned interiors and electrically operated automatic sliding doors.
They will be equipped with a regenerative braking system ensuring significant energy savings and capable of speeds of up to 80 km/hr, said Alstom in a release.
Alstom totally will supply 168 cars for the Chennai Metro, and the contract includes an option for 16 additional metro cars. The first delivery from the company’s facility in Sao Paulo, Brazil, started in 2012.
The total number of trains ordered from Alstom Transport in the first phase is 42 trains. Following the initial import of nine trains, Alstom set up a factory in Sri City, around 55km north of Chennai, as a measure to promote indigenization and technology transfer of metro train manufacture.
In addition to supplying the rolling stock, Alstom equips the trains with a signalling system for Automatic Train Protection and Automatic Train Operation.
The trains have first class seats and have an emergency system through which passengers can communicate to the train operator.
The seven trains that are now operational periodically undergo checks by a team from CMRL rolling stock maintenance department. The regular procedure, as per the monthly schedule, includes a 72-hour check and routine external train cleaning using automatic wash plant at the maintenance depot.
A routine static test has been completed on one train at the factory in Sri City and officials are conducting the final inspection before it is dispatched. Five other trains are under various stages of production.
Earlier in March, metro rail successfully conducted a trial run between Alandur and airport. The line is part of the Saidapet-Alandur-Airport elevated stretch of the 23.1-km Washermenpet-Airport corridor. Trial runs with rolling stock like locomotives and coaches is expected to commence soon.
The trial run on the stretch comes eight months after the inauguration of the line between Koyembedu and Alandur.
A trial run was also conducted from Little Mount to OTA successfully in October 2015. Electrification of the CMRL line between Thirumangalam and Shenoy Nagar is in progress and the trial run is expected to begin in a few months, an official said.
The metro project, which is coming up at a cost of around ₹15,000 crore, consists of two interconnected lines linking North Chennai to the airport in the South and Chennai Central to St Thomas Mount. It will include 32 stations –19 equipped with full size platform screen doors – over 45 km (24 km underground and 21 km elevated).
