Maintenance work will cause delays on several Metro lines this weekend.
Starting at 10 p.m. Friday, Red Line trains will be sharing a single track between the Van Ness and Friendship Heights stations and between Takoma and Forest Glen. Metro officials say that will add about 20 minutes to the normal travel time.
Meanwhile, Orange and Blue Line trains will be single-tracking between Eastern Market and Stadium Armory while crews replace rail fasteners to make for a smoother ride. There will also be 20-minute delays there through the weekend.
And from 7 a.m. to 4 p.m. Saturday, surveying work on the Green Line will have trains sharing a single track between the Greenbelt and College Park stations. Delays there are expected to be about 10 minutes.
