Four of Metrorail’s six lines had issues this morning causing crowded trains and lengthy delays for thousands of riders.

A switch problem near Stadium Armory station caused Blue, Orange, and Silver Lines trains to single track around 6:30 a.m. Then a power issue on the Red Line caused trains to share the track between Van Ness and Friendship Heights stations around 7:30 a.m. And Blue, Orange, and Silver Line service saw additional delays due to broken down train at Foggy Bottom station just before 8 a.m.

While some riders waited over an hour for trains, others found alternative transit options. And many people grumbled on social media about the inconvenience.

All of the issues were resolved by 9 a.m., but there were residual delays thereafter.

Metro now says service is normal on the Blue, Silver, and Orange Lines outside of Stadium Armory station. And additional Red Line trains are running between Silver Spring and Van Ness stations providing service every 8 to 10 minutes between those stations.
