Metro plans to suspend much of its track work for the weekends before Christmas and New Year’s – during what is typically the lowest ridership month of the year.

The transit agency plans to force Green Line trains to share a single track between Greenbelt and College Park during both this coming weekend and the next, Dec. 29-30. But all other lines will have normal weekend service, a change from recent weeks when the agency has been undertaking major work including shutdowns.
