On Monday, a T rider posted a video on YouTube that shows an unsettling sight - a Red Line train operating with an open door.
YouTube subscriber Erika Myllmaki wrote, "I got on at Quincy Center and one side of the door door next to me wouldn't shut even when the train was moving. This is inside the tunnel pulling up to Andrew (Station)."
Pesaturo said one of the door’s components malfunctioned, causing it to stay open.
“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 said.
“All of the older Red Line cars are being checked.”
