Metrorail Back to Normal Service Wednesday
Here's what's happening with transit a day after several inches of snow fell on the region:
Metrorail: Regular weekday service has resumed. However, remember that the current SafeTrack surge remains in effect on the Blue and Yellow lines. SafeTrack shuttle buses are running again between Franconia-Springfield and the Pentagon.
Metrobus: Metrobus was scheduled to begin the day on a moderate snow service plan, but WMATA said early Wednesday that Metrobus had actually resumed regular weekday service. However, adjustments and delays may be possible on isolated routes due to road conditions.
MetroAccess: Service for customers with disabilities has been restored. The MetroAccess reservations call center reopened at noon Tuesday so customers could schedule rides. However, Metro warned that some trips may still be delayed due to snow and ice.
Amtrak, meanwhile, is operating on a modified schedule Wednesday:
- Acela Express and Northeast Regional trains are running on a modified schedule between New York City and Boston, with some trains truncated or cancelled.
