Update (Saturday, Dec. 7, 11:30 a.m.): According to an email statement from Metro, "Metro has cancelled all scheduled rebuilding work on Sunday, Dec. 8, to allow crews to prepare for—and respond to—expected winter weather conditions. The move also allows Metro to allocate additional resources to preparing the system for Monday morning's commute."
Original post (Friday, Dec. 6, 2 p.m.): Expect Red Line trains to run every 10 to 20 minutes this weekend, from 10 p.m. Friday to closing on Sunday, Metro advised on its website.
Red Line trains will run every 10 minutes between the Grosvenor and Silver Spring stations from 9 a.m. to 9 p.m. on Saturday and Sunday.All other trains (i.e., between Grosvenor and Silver Spring before 9 a.m. and after 9 p.m., and beyond Grosvenor and Silver Spring at all times) will run every 20 minutes, Metro reported.
The delays will accommodate scheduled improvements to third-rail infrastructure and track conditions between the Twinbrook and Grosvenor stations, as well as leak mitigation and track improvements between the Forest Glen and Glenmont stations.
