PHILADELPHIA — Emergency workers here on Wednesday searched through the wreckage of a New York-bound Amtrak train that derailed and overturned late Tuesday, killing six people, injuring dozens more, and disrupting train service for thousands of riders in the Northeast region.
Investigators from the National Transportation Safety Board were expected to arrive in the morning and join officials from multiple other agencies trying to determine what caused the crash.
The train carrying 243 people was headed to New York from Washington when it derailed around 9:30 p.m., officials said late on Tuesday. Sixty-five people, including six who were in critical condition, were taken to hospitals, the mayor of Philadelphia, Michael A. Nutter, said.
“It is an absolute disastrous mess,” Mr. Nutter said. “I have never seen anything like this in my life.”
After the crash, emergency workers carrying flashlights and ladders moved frantically from car to car helping passengers off the train, some bloodied, others dazed.
