The cleanup continues in Washington state where a commuter train derailed while hurtling over a highway overpass, spilling some of its cars onto an Interstate below. The deadly crash saw an Amtrak train jump the tracks in the town of Dupont, 80 kilometres south of Seattle, while on its maiden run on a new, faster route and on upgraded track. Three people were killed and more than 70 others were sent to hospitals. Federal investigators say the train was travelling at just under 130 kilometres an hour — more than double the speed limit. An ad hoc army of assistants sprang into action to aid passengers aboard the crumpled train, including a neurosurgeon, and dozens of volunteers from a nearby military facility.
