UPDATE 5:23 P.M.

Trains are no longer single-tracking, according to a tweet from WMATA, but commuters should expect residual delays in both directions.

A WMATA spokesman said repairs on a small crack on the rail were completed, and a test train would be run through the area before two-track service was restored.

UPDATE 4:39 P.M.

A WMATA spokesman said the agency was investigating the report of a cracked rail, but crews were not yet on the scene.

On the Silver Line, trains were operating between Wiehle-Reston East and Clarendon only to reduce congestion, according to a tweet from WMATA, and commuters should use Blue and Orange Line trains to continue their trips.



The Blue and Orange lines were single-tracking in part of downtown Washington during Wednesday’s rush because of a track problem, authorities said.

At around 4:10 p.m., Metro tweeted that the Blue and Orange lines were single-tracking between Smithsonian and McPherson Square, and that there were delays in both directions.

Silver Line trains are operating only between the Clarendon and Wiehle-Reston East stations.
