5:17 P.M. Update:
The single-tracking cleared up at around 5:15 p.m., according to Metro, but delays remain in both directions.
The Orange and Blue lines are single-tracking between Foggy Bottom and McPherson Square due to a disabled train at Farragut West. Travelers should expect delays in both directions.
This follows earlier single-tracking on the Red Line between Silver Spring and Forest Glen. That single-tracking was cleared up a short time ago, but delays remain in both directions.
