A cracked Yellow Line rail, caused by the recent dramatic downward swing in temperatures, is forcing trains to use a single track near the Pentagon.
The track problem is causing 20-30 minutes delays on the Yellow Line and slight delays on the Blue Line, according to WMATA. As a result, Metro is advising customers to use the Blue Line instead of the Yellow.
Crews will not be able to fix the cracked rail until after the morning rush hour, according to Metro spokesman Dan Stessel.
