With the holidays over, Metro has announced weekend maintenance plans that will affect rail service on all five lines this weekend. The work requires trains to share tracks or alter schedules, but all stations will be open.

Here’s the plan for service adjustments, starting at 10 p.m. Friday and continuing through the trains system’s midnight closing on Sunday. Wizards fans, note that this could affect your return from the Friday night game at Verizon Center and train travel to and from the Sunday afternoon game.

Red Line: Trains will share tracks between Dupont Circle and Friendship Heights and between Takoma and Forest Glen. They will leave the ends of the line at Shady Grove and Glenmont every half hour throughout the weekend. But between 9 a.m. and 9 p.m. Saturday and Sunday, extra trains will operate between Fort Totten and Farragut North.

Blue/Orange lines: Trains will share a track between Smithsonian and Eastern Market. They will leave the ends of the lines about every 26 minutes. Through the inner part of the train system, where these two lines join, trains should arrive at platforms about every 13 minutes.

Green Line: Trains will share tracks between Georgia Avenue and Fort Totten and between Naylor Road and Branch Avenue. They will leave the ends of the line about every 15 minutes.

Yellow Line: Trains will operate every 15 minutes to align schedules with Green Line trains, which share a tunnel through the District.
