Railroad tracks between Seattle and Bellingham seem to suffer from frequent landslides leading to track closures. So why were the tracks built in slide-prone areas? How often do slides shut down rail traffic (commercial and passenger) and how much time does it add to freight deliveries? (And does it mean we use rail less than other metro areas? Do we put more on trucks?) Has a slide ever hit a train? And are hazardous materials transported along that stretch of track? How does unreliability of Amtrak service along the route impact ridership between Seattle and Everett?
