mg, it looks to me like you should forget the train and just take the bus between Everett and Seattle. It's obvious that that stretch of track is through very unstable terrain. (or should I say terrane?)
==========
"A mudslide onto railroad tracks between Seattle and Everett this afternoon has shut down Amtrak and Sounder service for 48 hours, according to BNSF Railway spokesman Gus Melonas.

The slide, which occurred at 2:05 p.m., was south of Mukilteo on the BNSF double mainline and was 25 feet long by 10 feet deep, Melonas said. It's the third slide on BNSF tracks between Seattle and Everett this winter, Melonas said.

Last year, mudslides interrupted service on the line multiple times, and BNSF Railway made significant engineering enhancements to the area where most of those slides occurred. There have been no further slides in that area this winter, Melonas said.

Today's slide was about a mile north of the stabilization work, he said, and within two miles of another slide this winter. The third slide this winter was in the Everett area.

Melonas said BNSF is looking at engineering plans for other slope areas along the tracks."

One year ago, the DH and I took a Trailways bus from Galesburg IL to Peoria and back. The bus was immaculate and the passengers were nice. I'm ready to try more bus travel.

And if there's a slide on its usual road, a bus can always take a different road.
