Failure to provide effective mitigation of a hazardous curve and the inadequate training of the locomotive engineer led to the deadly derailment of an Amtrak train near Dupont, Washington, in late 2017, the National Transportation Safety Board (NTSB) announced yesterday.
Three of 77 passengers were killed and 65 others were injured on Dec. 18, 2017, when Amtrak Cascades train 501, on its inaugural run on the Point Defiance Bypass between Seattle and Portland, Oregon, derailed on an overpass as the train entered a 30-mph curve at about 78 mph.
