Metro announced that 464 rail cars will be inspected after a friction ring fell off a train on the Orange Line on Friday, leaving passengers stuck on the train.
It's the same thing that happened just two weeks ago and ends a week of train troubles.
Metro says the problem on the Orange Line train at the Stadium Armory stop was with a friction ring that fell off one of the cars. The friction ring is used to help slow down and stop the train.
Passengers were evacuated.
The incident today is identical to the problem that occurred just over two weeks ago on a Blue Line train just outside the L'Enfant Plaza stop.
The ring fell off that train and touched the live third rail. No one was hurt then. And luckily no one was injured today. But it did back up service.
Metro released the following statement at 4:18 p.m. Thursday:
Metro to inspect 464 rail cars following mechanical incidentMetro will inspect 464 rail cars following an incident earlier today in which a brake part became detached from an Orange Line train.
The New Carrollton-bound train became mechanically disabled near Stadium-Armory station shortly before noon today. The train was brought to a safe stop, and passengers were transferred to other trains at Stadium-Armory.
Upon responding to the incident and conducting an onsite inspection, Metro discovered that one of its rail cars, car #2072, lost a friction ring, which is part of the brake assembly.
There were no injuries, and normal service was restored at approximately 2:30 p.m.
Metro has 464 rail cars with similar brake assemblies: the 2000, 3000 and 4000 series cars.
The inspections will continue through the weekend and into the early part of next week.
Metro currently has a fleet of 1,142 rail cars.
