The Delhi Metro Rail Corporation (DMRC) might change operational procedures to avoid derailment of trains in future.
On Wednesday, a Metro train with 34 passengers on board got derailed seconds after leaving the Dwarka Metro station in southwest Delhi. DMRC suspended the driver blaming human error behind the incident.
DMRC has constituted a three-member committee to investigate the incident. The committee will also come out with suggestions to avoid any such eventuality in the future, spokesman Anuj Dayal said.
“There could be new procedures and the operational system may have to be changed to avoid such an incident,” he said.
The derailment happened at 3.19 pm when the train, destined to Yamuna Bank station, just left Dwarka Main station. The driver of the train, DMRC said, overshot a signal when he should have stopped at the station.
The train was being driven in manual mode and was supposed to switch tracks after the signal. As the driver went ahead without getting a green signal, the tracks were not yet switched and the front four wheels got derailed.
While train operation on the underground section of Delhi Metro (Jahangirpuri-Central Secretariat) is completely automated—with the driver only closing and opening the doors —the elevated lines are not completely automated.
“The elevated sections too could be upgraded from Automatic Train Protection (ATP) to Automatic Train Operation (ATP) system. The ATO system, however, is much more expensive than ATP,” Dayal said.
While blaming the mishap on the driver, DMRC claimed its selection procedure for recruiting drivers is very stringent.
The recruitment process comprise four stages—written exam with negative marking, psychological test to check candidate’s mental make up and ability to respond in crisis situations, interview and medical examination in a government approved hospital with toughest medical standards of A1 category.
“Before taking charge of a train, all train operators undergo breath analyzer test at crew control and only then they are allowed to operate a train,” Dayal said.
