A train operator has been placed on paid leave while Metro investigates why the doors of a Green Line train opened on the wrong side Friday evening, exposing riders to the open track at L'Enfant Plaza.
The train heading to Greenbelt pulled into the station around 7:16 p.m., according to Metro spokesman Philip Stewart. Officials believe the doors were opened on the left side of the train - the non-platform side -- for about three seconds along the entire length of the train.
"The train operator has been removed from service and the investigation is ongoing," Stewart said. "Discipline will be assessed based on the investigation findings."
The incident is the latest case of train doors opening either on the wrong side or while trains are moving. A Green Line train operator was disclipined after opening the doors over open track in July. And in May, train doors opened twice while a train was moving due to what Metro said was a mechanical problem.
