// Strategic Significance
The Amtrak Cascades corridor between Seattle and Portland runs along Puget Sound through Pierce County and was the site of the December 2017 DuPont Washington derailment when a new route section opened and a train traveling at 80 mph on a 30 mph curve derailed killing 3 passengers and injuring 57. The corridor is in the Cascadia Subduction Zone earthquake area. Mudslides from the Cascades foothills are a recurring hazard along this route. The corridor passes over Puget Sound on bridges vulnerable to earthquake damage.
