NEW DELHI: Delhi Metro's experiment with its new driverless trains hit a roadblock on Friday with two trains colliding at the Kalindi Kunj depot at 3.45pm on Friday.
Delhi Metro Rail Corporation (DMRC) officials blamed Hyundai Rotem - the company manufacturing and delivering the trains - for the incident, which occurred while the new trains were being commissioned for trials.
Testing of trains on the Janakpuri (west) to Botanical Garden section - between Okhla and Botanical Garden - had started some months ago. The trains collided sideways, resulting in substantial damage on the
bodies of the coaches. Moreover, the incident cast doubt over the safety of driverless trains, which the Delhi Metro would be deploying for the first time in two new corridors of phase III - line 7 and 8.
Anuj Dayal, DMRC spokesman, however, tried to allay fears and said that the trains had not been fitted with all systems yet. "This was not an incident of direct head-on collision. Instead, it was a case of one train being hit from the side when another train (which wasn't commissioned) was reversed from the rear coach by Hyundai Rotem's staff, who had no direct view of the front. The speed of the train was 2-3 kmh minimising the impact," he said.
According to Dayal, the trains were being delivered to the depot by Hyundai Rotem, for trials that would be conducted after all systems were fitted into them. "This train was neither run by DMRC's train operator nor functioning on the signalling UTO system during this pre-commissioning stage," added Dayal.
According to him, once all the systems were in place, including safety and sensors, the trains were tested rigorously . "Friday's incident happened before the systems were fitted into the train," explained Dayal.
Meanwhile, the Delhi Metro has ordered an inquiry into the incident as contrary to norms the second train was allowed to be reversed from the rear coach. Normally trains go to the end of the line and were driven around.
"The visibility to the front is limited in the rear coach, so these trains were not allowed to be reversed. The inquiry would focus on how this was allowed," added a Delhi Metro official.
Reiterating the safety aspects of the new trains, Dayal said, "Mainline train operations are fully safe and there is no scope of any such collision due to provision of ATP (Automatic Train Protection) and ATO (Automatic Train Operation) during passenger services." In these two systems, the trains are run with automatic supervision and operation and brakes are immediately applied if there is any breach of authorised speed or movement of the train by the operator, he added.
