 Investigations identified human operational error as the primary cause.
This occurred on the Blue/Orange Line, and resulted in the both lines being shut down. At that time, the Blue Line ran from National Airport Station in Arlington to Addison Road Station in Maryland, and the Orange Line ran from Ballston Station in Arlington to New Carrolton Station in Maryland. The derailment occurred on the section where the two lines share the same cross-town subway route, and the wrecked subway car blocked both tracks. The other (then) open line, the Red Line, was not affected.
