"Our community of faith is praying for the victims and families of the train derailment as well as the first responders and emergency personnel on the scene," said Greg Magnoni, spokesperson for the Seattle Archdiocese.

At about 7:40 a.m. local time, Amtrak Cascades Train 501, with 78 passengers and five crew members aboard, derailed off of an overpass in DuPont. A number of the train cars fell onto Interstate 5 below, crashing onto vehicles on the highway.

At least three people died. More than 70 people were taken to local hospitals. Ten were reported to have serious injuries.

"My prayers are offered for all the victims of the terrible train derailment south of Seattle. These things are always a tragedy, but this one hits very close to home," Portland Archbishop Alexander K. Sample said in a tweet.

The night of the tragic accident the National Transportation Safety Board announced that the Amtrak train was going 80 mph in a 30-mph zone for that portion of the track. It derailed along a curve and a total of 13 train cars jumped the tracks. The derailed cars were removed the morning of Dec. 19, news reports said.

One of the dead was identified as Zack Willhoite, who was an employee of Pierce Transit. The transit authority provides public transportation in Pierce County, which includes Tacoma and DuPont. The other two people who died had not yet been identified as of mid-day Dec. 19. Another of those who died was identified as Jim Hamre, a retired civil engineer with Washington state's Transportation Department.

NTSB officials continued to investigate the cause of the accident, which took place on the first day of a new route for Amtrak. News reports said the tracks had been upgraded to allow higher-speed trains, but the curve where the train derailed was a 30-mph zone.

AP reported that investigators would be interviewing the engineer and other members of the crew, as well as review devices from the lead locomotive and rear engine that record data on every train trip. The derailed train also had two cameras on board, which were damaged but officials still hoped to get images to study.
