At 1:09 p.m., the transit agency said in an alert to its riders that trains were running between Huntington and Largo Town Center stops and between Franconia and Van Dorn Street stops. Buses are replacing train service between the Van Dorn Street and King Street stations.

At 1:27 p.m., Metro sent another alert. It advised riders that some rail service along the Blue Line had been restored. Trains are sharing a track between Braddock Road and Van Dorn Street stations.

But it warned that riders should expect delays in both directions.
