It's beginning to feel like a weekend routine on the Red Line -- crews are working on the station platform at station and that has trains sharing a single track between Shady Grove and Twinbrook. Metro says it will take up to 20 minutes longer than usual to get through that area. Similar delays are expected between Rhode Island Avenue and New York Avenue due to maintenance.
On the Green Line, rail work between Georgia Avenue/Petworth and Fort Totten is causing delays.
And people taking the Blue and Orange Lines between Stadium/Armory and Eastern Market should add 20 minutes to their travel time for installation of communications cables.
Meanwhile on the Blue Line between Arlington Cemetery and Pentagon City passengers should expect delays as crews work on the electric third rail.
Service is expected to be back to normal Monday morning.
