Red Line riders were encountering delays Thursday afternoon due to a cracked rail near Bethesda, according to Metro. Trains are single-tracking between Friendship Heights and Medical Center as a result of the cracked rail. 

Metro expects that the situation will be resolved before the evening commute, said Caroline Lukas, a spokeswoman for the transit agency.

The single-tracking and ensuing delays have been impacting riders for several hours. The cracked rail began slowing riders since shortly before 11 a.m., Lukas said.
