This will be a relatively light weekend for schedule disruptions on Metrorail. All stations will be open. But on the Red and Orange lines, the schedules are adjusted because trains will share single tracks around work zones from 10 p.m. Friday through the rail system’s midnight closing on Sunday.

Red Line. Crews will work on the tunnel leaks and repair catwalks between Dupont Circle and Van Ness. Between Forest Glen and Takoma, they will work on track insulators and the railroad ties and fasteners, in addition to fixing leaks.

Trains will leave the ends of the line at Shady Grove and Glenmont every 24 minutes throughout the weekend, the transit authority said. Between Dupont Circle and Fort Totten, additional trains will be in service from 9 a.m. to 9 p.m. Saturday and Sunday. Trains should reach those platforms in the middle of the line about every 12 minutes.

Orange Line. Crews will continue rebuilding the platforms at Deanwood and Minnesota Avenue. They also will work on track maintenance between Stadium-Armory and Cheverly. Between Ballston and East Falls Church, they will work on the rail joints, a project that Metro says should smooth the ride.

All along the line, trains are scheduled to reach platforms about every 24 minutes throughout the weekend.
