If you're taking Metro around Reagan National Airport on Sunday, plan extra time because of a station closure.
The Crystal City Metro station, which serves yellow and blue lines, is closed for an emergency response drill. Shuttles will replace trains between the National Airport and Pentagon City stations.
Regular service is scheduled to return at 2 p.m.
Other Metro lines are also moving slowly on Sunday.
Red Line trains run every 28 minutes. Trains are single tracking between Dupont Circle and Judiciary Square stations.
The Orange Line is also single tracking between Cheverly and New Carrollton. Trains run every 20 minutes.
