Red Line trains will single track this weekend through two work zones, Metro reported on its website:

• Between the Shady Grove and Twinbrook Metro stations.
• Between the Rhode Island Avenue and Takoma Metro stations.

The work will begin at 10 p.m. on Friday, Feb. 8, and continue through closing on Sunday. The single tracking will enable work crews to perform platform reconstruction, track maintenance and third-rail upgrades, Metro reported.

Throughout the weekend, Red Line trains traveling between Shady Grove and Glenmont will operate every 24 minutes. Between 9 a.m. and 9 p.m. on Saturday and Sunday, additional Red Line trains will operate between Grosvenor and NoMa-Gallaudet to provide service about every 10 minutes between those Metro stations, Metro added.

Metro advised passengers traveling through either of the work zones to add on about 15 minutes to the anticipated travel time.
