Normal Red Line service has resumed after a track problem left trains single-tracking for a short time Tuesday morning.
Tuesday marked the second day in a row that problems plagued the line.
Trains started single-tracking between the Van Ness and Dupont Circle stations about 5:30 a.m., and riders were told to expect delays.
Metro said a track problem at the Woodley Park station was to blame.
Normal service resumed at 6:45 a.m.
Unscheduled track work left trains single-tracking between the same stations Monday morning.
