An Amtrak train operating from Seattle to Portland derailed on a bridge near Tacoma, Wash. on Monday morning, killing at least three people and injuring as many as 100. The Amtrak Cascades Train 501 was carrying approximately 78 passengers and five crew members, when it careened off an overpass onto Interstate 5 below, leaving one rail car dangling and one upside down.

Local officials said that several vehicles on the roadway were involved in an ensuing pileup, but no motorists were reported killed.
