You may need to set aside some extra time if you use Metro's Green or Yellow line.
Train service was suspended on parts of the Green and Yellow line for a short time Monday morning due to late-clearing track work, Metro said on Twitter.
Trains on the Yellow Line shared a track from Pentagon City to Mt. Vernon Square for about an hour, but they are no longer single-tracking, according to Metro. On the Green Line, trains are no longer single-tracking from Navy Yard to Mt. Vernon Square.
Trains were also single-tracking on the Red Line, but normal service has resumed.
Riders should expect delays in both directions on all three lines.
