Metro has adjusted its SafeTrack rebuilding schedule to accommodate additional work on interlockings, the points where trains change tracks, after a derailment in July raised questions about the safety of its track infrastructure.
The seventh SafeTrack surge, which is currently being conducted between Shady Grove and Twinbrook, will be extended through Sunday to accommodate a new weekend shutdown. The work was originally scheduled to conclude Thursday.
Beginning Saturday, free shuttle buses will replace Red Line trains between Grosvenor and Shady Grove as Metro closes four stations: White Flint, Twinbrook, Rockville and Shady Grove.
Red Line trains will continue single-tracking between Shady Grove and Twinbrook through Friday.
Surge #8, originally scheduled to begin Saturday, will be pushed back to Saturday, Aug. 27, and continue through Sept. 11. In addition to weekday single-tracking from Franconia-Springfield to Van Dorn Street, the surge now encompasses three consecutive weekend shutdowns as crews work to rehabilitate a switch in the area.
Aug. 27-28, Franconia-Springfield station will close and shuttle buses will provide service to Van Dorn Street. Then from Sept. 3 through 5, including Labor Day, shuttle buses will replace trains from Franconia-Springfield to King Street. Franconia-Springfield and Van Dorn Street stations will be closed.
Franconia-Springfield station will again close from Sept. 10-11, with shuttle buses to Van Dorn street, as the work concludes.
The ninth SafeTrack surge, which includes daily single-tracking between Vienna and West Falls Church, will be pushed back to Sept. 15 and continue through Oct. 26. It will also include four new weekend shutdowns — from Sept. 24-25, Oct. 1-2, Oct. 8-9 and Oct 15-16. Vienna and Dunn Loring stations will be closed for all four shutdowns. West Falls Church will be closed for the first two.
