Orange, Blue, Green and Yellow Line riders: your numbers are up for single-tracking this weekend. Here’s your weekend maintenance schedule:

Orange Line:
>> Between the Vienna/Fairfax-GMU and West Falls Church-VT/UVA Metrorail stations, trains will single-track from 10 p.m. Friday through closing on Sunday. Riders should add at least 30 minutes to their travel time.
>> On Saturday and Sunday, every other Orange Line train in the direction of Vienna/Fairfax-GMU will terminate at West Falls Church-VT/UVA — so if you need to go beyond West Falls Church, you might need to wait for the next train.
>> On a related note, Metro will single-track between the two Falls Church stations for four hours every weekday — between 10 a.m. and 2 p.m., starting on September 27 and ending on October 8. Delays should be minimal, though.

Blue and Yellow Line:
>> Between the Pentagon City and Braddock Road Metrorail stations, trains will single-track from 7 a.m. to 6 p.m. on both Saturday, September 25 and Sunday, September 26. Riders should add at least 30 minutes to their travel time. During this single-tracking on Saturday and Sunday, Blue Line trains between Franconia-Springfield and Largo Town Center will operate approximately every 30 minutes. Same deal for Yellow Line trains between Huntington and Mt. Vernon Sq/7th St-Convention Center Metrorail station.

Green Line:
>> Metro needs to trim the weeds between the Branch Avenue and Naylor Road Metrorail stations. Trains will single-track between those stations from 7 a.m. to 6 p.m. on Saturday, September 25, and 7 a.m. to 2 p.m. on Sunday, September 26. Riders should add at least 20 minutes to their travel time between said stations during those periods.
