A cracked rail on Metro's Red Line near Tenleytown disrupted service all morning until crews replaced a 40-foot stretch of rail. Service was restored shortly before 12:30 p.m.
For more than five hours, the problem forced single tracking between Van Ness and Friendship Heights, with every other Red Line train turned back to the Silver Spring station at Farragut North.
Thousands of commuters were delayed by the latest in a long list of problems for Metro. Many were scrambling for buses or taxis.
Some complained that Metro said that shuttle buses would be provided, but they then found out the buses were for disabled people only.
Metro tried to ease the confusion and apologized for the delays, saying they're trying to fix a lot of things quickly.
The Red Line is Metro's oldest and most heavily used segment. And many commuters are coming to expect the worst, from cracked rails to broken escalators to brake parts falling off trains.
