Man, what a day. Just to update those of you still reading at this late hour: Metro is now reporting “emergency track work” at Mt Vernon Sq 7th St-Convention Center. Trains are sharing the same track between Mt.Vernon Sq and U Street-Cardozo stations, causing delays in both directions, and as of 7:10 p.m., they don’t expect it to be fixed for at least 2 more hours. Add this Green/Yellow line delay to the existing problems on the Orange line between East Falls Church and West Falls Church, and you’ve got a really long late evening commute for all the workaholics still at their desks (or, preferably, those of you heading out to bars). Good luck out there.
