The move comes a day after Metro pulled the 3000-series cars from service after a set of doors opened on an Orange Line train as it left the Dunn Loring station Sunday. A rider caught the incident on video.
Metro General Manager Paul J. Wiedefeld said Wednesday at a news conference about the upcoming closure of six Blue and Yellow stations, that an initial review showed there was an electrical component in the 3000-series car that “didn’t perform the way it was supposed to” and the doors opened.
He said 26 cars in the agency’s fleet of roughly 1,200 rail cars have a similar type of component and they have been removed from service. Wiedefeld said the parts on those 26 rail cars will be replaced.
Wiedefeld said the train involved in Sunday’s incident kept moving because the component didn’t work and the train operator didn’t know the door was open because “the electronics didn’t work the way they were supposed to.”
The Washington Metrorail Safety Commission, which is responsible for safety oversight of the transit agency, has launched an investigation into the incident.
This isn’t the first time Metro has had problems with doors opening while a train is moving.
In 2015, the agency’s 4000-series cars had to be pulled from service for a door problem. A year later, the 4000 series was again pulled from service after engineers discovered a glitch that posed a collision risk. The series has since been retired.
Wiedefeld said there have been no previous issues with doors opening on the 3000-series trains.
The 3000-series went into service in the late 1980s.
