Blue and Orange Line trains are single tracking between D.C. and Arlington due to a derailment at Rosslyn station.

The incident was first reported by WMATA as a “track problem” around 7:15 p.m. Minutes later the agency announced that Blue and Orange Line service was temporarily suspended in between D.C. and Arlington due to a “minor” derailment. No injuries have been reported and WMATA says passengers on the train were “safely moved to platform.”

Trains started single tracking around 7:30 p.m. and are now running with a 20 minute headway, according to Metro. The agency is advising Blue Line passengers to use the Yellow Line between D.C. and Virginia, if possible.
