Metro’s nine-month maintenance surge will soon affect riders on the heavily traveled red line for the first time.

Starting on August 1, trains will be sharing a single track in both directions between the Silver Spring and Takoma stations, disrupting the commute for thousands of Maryland residents. The single-tracking will last for one week.

On July 27, Metro general manager Paul Wiedefeld will join officials from Montgomery County, the District of Columbia and Takoma Park at a news conference to discuss what riders should expect. Commuters are being strongly encouraged to find other ways to get to work.

So far, Virginia commuters have been more broadly affected by the shutdowns and single-tracking involved in Metro’s maintenance surge, which started in June.

Because of the maintenances surges, Metro has been closing earlier on the weekends.

Metro’s general manager is proposing that the Washington-area subway system should close at midnight on a permanent basis to allow for ongoing maintenance.

Metro suspended late-night service in May before it launched its ongoing nine-month maintenance surge. The system had been open until 3 a.m. on Saturday and Sunday mornings. It’s now closing at midnight every night.

General manager Paul Wiedefeld is also proposing that Metro close even earlier on Sunday nights — at 10 p.m. Metro said in a statement July 26 that Wiedefeld consulted with other transit agencies and rail engineering consultants before proposing the new schedule.

Metro’s board of directors will have to approve the proposal, which Wiedefeld will present at a board meeting on July 28.
