A woman was struck by a Metro Red Line train at 9:25 a.m. at the Gallery Place/Chinatown station, says Angela Gates, a Metro spokeswoman. The woman apparently survived the accident, but there are no details on her name or her exact condition, Gates says.

The accident has limited service on the Red Line, Gates says. Passengers must now exit the Red Line at either the Farragut North or Judiciary Square exits. Gates did not know when full service may resume.

As far as the accident, the spokeswoman said it was still under investigation, and Metro does not yet know the cause.

Given the volume of passengers today, it’s somewhat surprising that more accidents haven’t occured. By 9 a.m. today, more than 409,000 people had already taken the Metro.
