CHENNAI: Six years for now commuters may get on the operator’s view as the travel by driverless trains long phase-2 metro corridors but may not be enjoy the same experiences on phase-1 lines as the new rolling stock cannot be run on the existing 45km line.
CRML has plans to operator driverless train in three corridors of the 118.9km in phase-2 where was entire operation of the train will be automatic. However, trains on phase-1 will continue to be operated by drivers.
A metro rail official said the signal systems required for the driverless train are different from those being used for train on phase-1. Hence trains on the both phases cannot be interchanged.
“The signal software controls the entire operation of the train as well as its associated systems. The rolling stock may look the same, but the software will vary in both corridors. So we cannot operate a train designed for phase-2 on phase-1,” an official said.
An estimated 138 three-car trains would be run at 4-10minute frequency to carry a projected 19.2lakh riders daily, when the first leg of phase-2 begins operation in 2025. CMRL plans to increase the fleet to 254 trains in three decades to cater to an estimated daily ridership of 43.5lakh. Signal software controls operation of the train, automatic train announcements on train and in stations, platform screen doors automatic fare collection gates and information display boards on the platforms.
Due to the technologically incompatible rolling stock commuters will have to exit phase-2 stations and reach phase-1 lines through exclusive subways and walkways planned. There will be interchanges linking stations of both phases in at least six locations, including KMC, CMBT, Anna Nagar, Vadapalani, Nandanam and St Thomas Mount. “It is not because of the trains, but the stations planned in phase-2 would not be built on the same road as phase-1. For instance, KMC station will come up on Barnaby Road while the present Kilpauk station is on Poonamallee Highway road. Commuters will have to use a walkway we will build to link the stations for switching corridors, an official said.
In phase-1, train operators manually stop and start the train at stations and open/close the train doors.
However, in phase-2, officials said the console will be less than one-fourth the size of those in the present fleet and will stay locked. In case of emergencies, the operations control centre (OCC) staff will take control of the operation until a controller of the nearest station, trained to operate a train reaches the spot.
