While trains on the other Metrorail lines operate on their normal weekend schedules, the Red Line’s east side is going to be split on Saturday and Sunday, with free shuttle buses taking travelers around the closed portion.

Meanwhile, crews will be working on communications cables and the replacement of light poles between the NoMa-Gallaudet and Fort Totten stations. The Rhode Island Avenue and Brookland stations will be closed.

The trains are scheduled to operate every 10 minutes on the open portion of the rail line. The buses between NoMa-Gallaudet and Fort Totten will stop at Rhode Island Avenue and Brookland. Metro estimates it will take the buses 10 minutes to get between each stop.

The line split will take effect at 12:01 a.m. Saturday and continue through the rail system’s midnight closing Sunday. This timing reflects a recent change in Metro’s policy on the major track work projects, which used to begin at 10 o’clock on Friday nights. The new schedule makes it a bit easier if, say, you’re going to a Friday night game at Nationals Park. Before the change, the train lines would be operating normally when you arrived at the stadium, but on the way home, you might have to get off a train, onto a bus, and then back onto a train again.

Splitting the Red Line this weekend also will change the times for the last trains of each night, so the trains can meet the last rounds of shuttle buses. On Friday and Saturday nights, the last trains from Glenmont to Fort Totten are scheduled to leave at 2:02 a.m. On Sunday, the last train will leave Glenmont at 11:02 p.m., Metro says.

Some Red Line riders will find it more convenient to switch to the Green or Yellow lines at Fort Totten for a trip downtown. Both lines will be operating on their normal schedules, Metro said. The only adjustment is on the Green Line at College Park station, where all trains will arrive and depart on the Greenbelt side of the platform.
