On November 3, 2004, an out-of-service Red Line train rolled backwards into the station, hitting an in-service train stopped at the platform. The rear car (1077) was telescoped by the first car of the standing train (4018). No one died, 20 people were injured. A 14-month investigation concluded that the train operator was most likely not alert as the train rolled backwards into the station. Safety officials estimated that had the train been full, at least 79 people would have died. The train operator was dismissed and Metro officials agreed to add rollback protection to more than 300 rail cars.
