A door problem on a Red Line train caused minor delays during the Tuesday morning rush hour, Metro officials said.
Metro spokeswoman Caroline Lukas said that at about 8:30 a.m., a train from Medical Center was stopped after the train’s all-doors closed indicator signaled an issue with a door.
The indicator is a light that alerts the conductor that not all of the doors are closed, and automatically triggers the train to stop, Ms. Lukas said.
This light can be triggered any a number of things, Ms. Lukas said, including something as simple as a passenger “leaning against a door, causing it to open a fraction of an inch.”
Once the train stopped, the operator performed a visual inspection, but “found nothing amiss, and no customers reported anything to the operator,” she said.
The train was restarted and offloaded at the Bethesda station and taken out of service.
Ms. Lukas said as of Tuesday afternoon, Metro had not determined the cause of the indicator signaling a problem.
