The MBTA said it removed a Red Line subway car from service Wednesday and inspected the doors of similar cars after a rider posted an online video showing a train traveling through tunnels with a door ajar.
“One of the door’s components malfunctioned, causing the door to stay open,” T spokesman Joe Pesaturo said in an e-mail. “Upon learning of the malfunction, Red Line personnel removed the subway car from service and took it to the maintenance facility for a repair.”
The cause of the malfunction is under investigation,he said. The car was an older model.
“With safety being a top priority, the Red Line has developed a new inspection procedure for the older Red Line cars that have this type of mechanism in the door,” Pesaturo wrote. “All of the older Red Line cars are being checked.”
Pesaturo said the incident happened Monday. Half of the door was stuck open; arider alerted T staff about it, and no one was injured, he said.
The YouTube video was posted Monday by Erika Myllmaki, who said she was traveling with her boyfriend.
“I got on at Quincy Center, and one side of the door next to me wouldn’t shut even when the train was moving,” she wrote in comments accompanying the video. “This is inside the tunnel pulling up to Andrew [Station].”
