A cracked third rail between the Arlington Cemetery and Rosslyn Metro stations caused at least four Blue Line trains to stop on the tracks, causing major delays and overcrowding on Blue, Orange and Silver Line platforms this morning.
The problems started before 8:00 a.m. as Blue Line trains traveling into D.C. from Arlington were becoming disabled when they were going over the cracked rail. On Twitter, one rider reported “Just past [Arlington National Cemetery] there was a loud pop and train went dark and shut off. We broke down after [Foggy Bottom].”
