It was the first day of high speed service for the area. It appears that the train came off the rails at a curve. Outlets reporting last known speed of ~81mph. The scene has been declared a mass casualty incident. Let’s hope everyone is okay, no formal count of injuries of fatalities yet...
If you are in Seattle, probably should avoid I5.
