I’m not sure what happened here. Angry Metro rider? Angry Redskins fan? Angry that the escalator wasn’t working? Rush hour jostling accident? General horseplay incident? Repair work flub? In any case, this escalator from the lower level of Metro Center to the Glenmont-bound Red Line platform has been closed for two weeks, and is now likely to stay closed for a bit longer while they replace the broken glass.
