DUPONT, Wash. (AP) — An Amtrak train that derailed south of Seattle and killed multiple people was making its first run as part of a higher speed service that local authorities had warned could be dangerous.

Transitdocs.com, a website that maps Amtrak train locations and speeds using data from the railroad’s train tracker app, says Train 501 was going 81.1 mph moments before the derailment Monday.
