A train derailment on the Blue and Orange Lines Tuesday caused major delays during the evening commute.
There were big delays on Metro's Blue and Orange Lines during Tuesday's evening commute, after a train derailed near the Rosslyn Metro station.
The Blue Line train involved in Tuesday's mishap, which Metro characterized as a minor derailment, is undergoing inspections at the New Carrolton station. Two Metro employees involved in the incident have been tested for drugs and alcohol, and have been placed on paid administrative leave, a step Metro calls routine in these types of situations.
However, the Washington Post is citing two unnamed Metro sources close to the investigation as saying human error may have played a factor in Tuesday's derailment incident.
The investigation revolves around a switch at that station that blocked the train from moving, and efforts made by the train operator, maintenance crews and staff at Metro's operations center to manually switch the train prior to its derailment failed.
No one was hurt in the incident, and crews had to work from 7p.m. Tuesday into early Wednesday morning to remove the train from the track and restore service to both the Blue and Orange Lines.
