Update: Metro has restored normal service on the Blue and Orange lines following the derailment. A news release issued at 4:06 a.m. said crews re-railed the wheels that went off track, made repairs and tested the track and switch equipment near the derailment's location.
A full Metro train carrying about 1,000 riders derailed about 7 p.m. Tuesday on the Blue Line outside of Rosslyn, according to Metro.
No one was reported injured when one set of wheels on a 3000 series rail car came off the tracks.
Officials were able to evacuate all riders from the train in less than 10 minutes because four of the six cars were along the station platform, Metro said in a written statement.
But the derailment delayed trains along the Orange and Blue lines as trains had to share a single track around the site. It was not clear as of 9:30 p.m. whether the track or rail cars were damaged, Metro spokesman Dan Stessel said.
Metro notified both the Tri-State Oversight Committee and the National Transportation Safety Board, Stessel said.
It was the first derailment involving passengers since February 2010, when a fully loaded train derailed in a side track just north of Farragut North. The NTSB’s investigation into that derailment is still pending.
