Taking the Metro to get around this weekend? Here’s what to expect Dec. 22-23.

According to a Metro news release:

The only planned work will take place on the Green Line, and will only affect customers traveling to or from Greenbelt Station.

Green Line trains will single track between Greenbelt and College Park to allow for construction associated with a new track to test 7000-series railcars. As a result:

• From 7 a.m. until 6 p.m. on Saturday and Sunday, every other train will originate/terminate at College Park, rather than Greenbelt.
• Green Line trains will operate normally, at regular weekend intervals, between College Park and Branch Avenue.
• Customers traveling to or from Greenbelt Station should allow about 10 minutes of additional travel time.
