Single-tracking on Red Line
8:12 a.m. Update: Metro says the disruption has been cleared at Rockviille. However, that means a return to single-tracking as the platform work at Rockville continues throughout the weekend.
Original post: Metro has discontinued train service between Shady Grove and Twinbrook stations due to emergency track maintenance. The transit authority is establishing shuttle buses to bridge the gap.
Metro planned to work on the deteriorated platform at Rockville this weekend as part of its Red Line rehabilitation, so trains were already single-tracking around the work zone.
