Metro’s service on all subway lines serving Capitol Hill will be disrupted in the months ahead as the transit system launches a “military operation” to make the commuter lines safer and more reliable.

The longest shutdown will come on the Red Line, when trains will not travel from NoMa-Gallaudet U to Fort Totten stations from Oct. 9 to Nov. 2; buses will be available to move commuters from one stop to another.

In addition, train traffic will slow down when Metro puts in place single tracking on the Blue, Orange, Yellow and Silver Lines from Aug. 20 to Sept. 6, affecting stations from Eastern Market to Minnesota Avenue and Benning Road.

Across the system, late-night weekend service on the Metro will stop at midnight beginning June 3 and stations region wide could be shut down for as long as a month, under a safety upgrade plan unveiled by General Manager Paul Wiedefeld last week.

Passengers can also expect 16 different stations served by five of Metro’s six rail lines to be either closed or offer limited service at various times. Passengers could wait for trains for up to 20 minutes, and track work during rush hour can also be expected.
