Washington state highway reopens after deadly Amtrak derailment

The affected southbound stretch of Interstate 5, which runs from the Canadian border to Mexico, opened on Wednesday afternoon, the Washington State Department of Transportation said. Federal investigators from the National Transportation Safety Board (NTSB) are seeking answers about the crash's cause in interviews with the train's engineer and a trainee conductor who were in the locomotive's cab. NTSB members say they are focused on whether the engineer was distracted, but are timing their interviews with the crew this week around their recuperation from injuries.
