Major Red Line Delays This Morning

We're hearing from a lot of people who had lengthy Red Line delays on their way in to work this morning, with anecdotal reports of sitting still for up to 35 minutes underground before getting going again. Metro says the delays are due to a track circuit malfunction outside the Dupont Circle station, which forced trains to single-track between Dupont Circle and Van Ness. The malfunction was, according to Metro, already resolved by about 8:30 a.m., but delays have been ongoing since then.
