No passenger train north of Seattle until Thursday
Spokesman Gus Melonas said the largest early Tuesday at Everett covered 50 feet of track up to 15 feet deep with mud, rocks and trees.
Freight trains have been running sporadically. Passenger trains are on hold as a safety precaution. No Amtrak or commuter rail trains will run between Seattle and Everett until 12:30 a.m. Thursday, at the earliest.
Melonas said sensors monitor steep slopes for slides and inspectors are checking the stretch of track that runs along Puget Sound under steep bluffs.
Mudslides have hit track between Seattle and Everett dozens of times in recent winters.
Melonas said the railroad has been working to improve ditches and culverts to protect the tracks.
