A packed metro rake covered the entire north to south stretch of Kolkata with one of its doors open during rush hours on Wednesday and three railway staffers guarding it.
The incident occurred at 10.24 am when the metro rake from Dum Dum metro station in north Kolkata to Kavi Subhash in the southern suburbs of the city crossed 22 stations with a door in one of its coaches open.
"There was a technical glitch in one of the doors of a coach. It was ensured that the door was guarded by an RPF constable, a loco inspector and another official. The train successfully completed its run.
"We could have immediately sent the metro rake to a car shed but doing so would have hampered the services during the peak office hours. So, we ran the train and ensured the safety of the passengers. The door has been fixed now," the spokesperson said.
Several incidents of technical problems have been reported in Kolkata Metro in the past few months.
A middle-aged person was killed in July when he was dragged by a metro rake after his hand got stuck in one of its doors.
