Update, 8:01 a.m.:

Red Line trains are no longer single-tracking, but delays continue as crowds fill stations for the morning rush hour.

The delays were the result of a cracked third rail between NoMa-Gallaudet and Rhode Island Avenue stations. Crews successfully completed repairs around 7:50 a.m., more than an hour after delays began.

Riders should expect residual delays and crowded delays for the next 30 minutes or so, Metro said.


Update, 7:17 a.m.:

Metro is directing impacted Red Line riders to take alternate train and bus routes:

Alternates from Fort Totten include the Green Line, Metrobus 80 to Union Station/Gallery Place and Metrobus P6 to Gallery Place.

Alternates from Silver Spring include Metrobus 70, 79 to Georgia Avenue or Gallery Place, and S-Line to Columbia Heights or McPherson Square.

An alternate from Rhode Island Avenue is Metrobus P6 to Gallery Place.

Update, 6:42 a.m.:

Metro is warning Red Line riders of “possibly significant” delays during the Wednesday morning rush hour.

A crack in the electrified third rail between NoMa-Gallaudet and Rhode Island Avenue stations has forced the transit agency to take one of the two Red Line tracks out of service. Trains will be single-tracking between NoMa-Gallaudet and Fort Totten until repairs can be completed.

No timeline for repairs is currently available, but Metro officials anticipate that the delays will impact much of the morning commute.

Riders are advised to use an alternate travel option, such as the Green Line or Metrobus, Metro said.

Original post, 6:26 a.m.:

Red Line trains are experiencing delays this morning due to a track problem near the Rhode Island Avenue station in Northeast Washington, Metro reports.

Trains are single-tracking between the NoMa-Gallaudet and Fort Totten stations. Riders can expect delays in both directions.

An earlier report from Metro indicated that there were also delays due to a disabled train at the Red Line’s Brookland station.
