LANHAM, Md. (CBSDC) — Green Line train service has been restored between Navy Yard and Southern Avenue stations, but Metro officials say to expect residual delays in both directions.

Green Line service was temporarily suspended for about an hour and a half as Metro personnel worked to fix a track problem near the Anacostia station. Shuttle buses were provided for commuters stuck at the suspended stations.

The track issue was described as an “arcing insulator,” a part of the third rail that was generating smoke due to wayward electrical current.

Green Line trains between Navy Yard and Southern Avenue stations originally were single-tracking but delays had extended to more than 40 minutes in both directions before service was suspended.
