WASHINGTON — Single-tracking will change service on all but the Orange Line on Saturday and Sunday.
Here’s what Metro service looks like for each line on Saturday and Sunday:
Red Line
On the Red Line, continued work to keep water out of a stretch of tunnel near Medical Center means trains are scheduled only every 15 minutes this weekend. Additional trains are scheduled during the day downtown.
Next weekend, on Nov. 18-19, there will be no trains between Medical Center and Grosvenor-Strathmore due to the work.
Green & Yellow lines
Green Line trains are scheduled every 15 minutes on Saturday and Sunday with single-tracking between Fort Totten and Prince George’s Plaza.
With the work, Metro is only running Yellow Line trains every 15 minutes, and only between Huntington and Mt. Vernon Square. Combined, that significantly increases scheduled wait times for riders between Fort Totten and Gallery Place-Chinatown.
Orange, Blue & Silver lines
Blue Line trains will single-track between Addison Road and Morgan Boulevard on Saturday and Sunday, but Metro said it should not cause delays.
Silver Line trains will run between Wiehle-Reston East and New Carrollton on Saturday and Sunday, instead of to and from Largo Town Center. While that reduces service between Largo and Stadium-Armory, it increases service between New Carrollton and Stadium-Armory.
Orange Line service is scheduled to operate normally.
