Here’s a look at the track work planned for this week through Thursday.
Red Line: Late in the evenings, trains will share a track between Dupont Circle and Friendship Heights for work on the track circuits. Trains also will share a track between Takoma and Forest Glen, where workers are installing fiber optic cable. Riders should allow 20 extra minutes.
Tonight and Wednesday, it will begin at 10 p.m. (The Capitals play Tuesday and the Wizards play Wednesday at Verizon Center. The games start at 7 p.m. ). On Thursday, the work will begin at 8 p.m.
Orange Line: At 10 tonight and continuing each night through Thursday, trains will share a track between Ballston and Foggy Bottom. This work will prepare for a switch replacement project.
Trains also will share a track between Eastern Market and Stadium-Armory, clearing areas for station rehabilitation and track work. Riders should add an extra 20 to 25 minutes to their normal travel times, Metro said.
Riders traveling between D.C. and Arlington also could take Metrobus Route 38B (Farragut Square-Ballston). Those buses stop at Rosslyn, Court House, Clarendon and Ballston Metrorail stations.
Blue Line: From 10 p.m. each night through Thursday, trains will share a track between Arlington Cemetery and Foggy Bottom. The work in this zone also prepares for a switch replacement project.
Trains will share a track between Eastern Market and Stadium-Armory for station rehabilitation and track work. Add 20 to 25 minutes to normal travel times, Metro said.
Green Line: From 10 a.m. to 2 p.m. Wednesday through Thursday, trains will share a track between Fort Totten and Prince George’s Plaza while crews work on the rails and fasteners. Add about 10 minutes to normal travel times.
Yellow Line: Because of the Green Line work, Yellow Line trains will turn back at Mount Vernon Square during midday hours, rather than continuing north to Fort Totten, as they normally do at off-peak times. Riders who want to go beyond Mount Vernon Square should switch to Green Line trains on the same platform.
