SEATTLE — Amtrak service north of Seattle and Sounder commuter rail trains between Seattle and Everett are scheduled to resume operation today after being shut down for 48 hours because of a mudslide.

A 20-foot-wide slide blocked the tracks near Mukilteo, Wash., about 6 a.m. Monday. While freight service resumed later that day, local rules require a 48-hour pause in service while ensuring there are no further slides.

Barring additional slides overnight, Sounder service was to resume this morning with a 7 a.m. train from Everett. The two daily Amtrak Cascades round trips between Seattle and Vancouver, British Columbia, should operate on normal schedules.
