CCTV footage revealed that Kumar was stepping out of the Metro at the Janakpuri West station around 11.15 pm on Tuesday when his ankle got stuck between the doors. When Kumar tried to free himself with his hands, the train started moving out of the station. Even as the train dragged him all the way to the next station, Janakpuri East, a fellow commuter held on to him from the other side. As the Metro corridor was elevated, Kumar escaped with minor injuries in his hand and ankle.

When the train reached the next station, the train operator freed Kumar’s hand by forcing the door open.

Delhi Metro officials said the Bombardier train was pulled out of service soon after the incident, and several tests were performed on it. However, the technicians were unable to identify why the automatic door had not detected the obstruction and reopened.

H S Anand, Director (Rolling Stock), DMRC, told Newsline, “During the tests, we tried recreating the incident by obstructing the same door, but this time it functioned as it was supposed to. All Metro train doors can detect obstructions that are more than 20 mm, and re-open on their own. The CCTV footage clearly shows that the passenger’s ankle — which was definitely more than 20 mm — was stuck in the door. We are still checking for the cause.”

“Even the train operator is being questioned over how he failed to notice that somebody was stuck between the doors. We should be able to get a final report on the incident by Thursday,” Anand said.
