Here’s a heads up if your holiday weekend travel plans include riding the rails. Metro plans to shut off rail service to stations on the northern end of the Green Line this weekend, including the West Hyattsville, Prince George’s Plaza,College Park and Greenbelt stations. Trains will stop running to those stations starting at ten Friday night and continuing through Monday, Memorial Day. Free shuttle bus service will be provided between Fort Totten and Greenbelt. Yellow Line trains will only be running between Huntington and Mount Vernon Square. In addition, trains will share a single track along the Red Line between Forest Glen and Takoma.
