During the Blizzard of 1996, on January 6, a Metro operator was killed when a train failed to stop at the station. The four-car train overran the station platform and struck an unoccupied train that was awaiting assignment. The National Transportation Safety Board (NTSB) investigation found that the crash was a result of a failure in the train's computer-controlled braking system. The NTSB recommended that Metro grant train operators the ability to manually control the braking system, even in inclement weather, and recommended that Metro prohibit parked rail cars on tracks used by incoming outbound trains.
