CHESTER, Pa. - An Amtrak train struck a piece of construction equipment just south of Philadelphia on Sunday causing a derailment, killing two people and sending more than 30 others to hospitals, authorities said.

Train 89 was heading from New York to Savannah, Georgia, at about 8 a.m. when it hit a backhoe that was on the track in Chester, about 15 miles outside of Philadelphia, officials said. The impact derailed the lead engine of the train, which was carrying more than 300 passengers and seven crew members.

Chester fire commissioner Travis Thomas said two people were killed, but neither was a passenger on the train. Authorities provided no additional information on the fatalities. Thomas and Amtrak officials said more than 30 people were taken to hospitals with injuries that weren't considered life-threatening.

The National Transportation Safety Board was investigating. Officials with the Federal Railroad Administration were also sent to the scene, said Matthew Lehner, a spokesman for the agency.

Service on the Northeast Corridor between New York and Philadelphia is operating after an earlier suspension. Service between Wilmington, Delaware, and Philadelphia remains suspended.

Ari Ne'eman, a disability rights activist heading to Washington after speaking at an event in New York, said he was in the second car at the time of the crash.

"The car started shaking wildly, there was a smell of smoke, it looked like there was a small fire and then the window across from us blew out," said Ne'eman, 28, of Silver Spring, Maryland.

Some of the passengers started to get off after the train stopped, but the conductor quickly stopped them. Officials started evacuateing people to the rear of the train and then off and to a local church.

"It was a very frightening experience. I'm frankly very glad that I was not on the first car," where there were injuries, he said. "The moment that the car stopped, I said Shema, a Jewish prayer ... I was just so thankful that the train had come to a stop and we were OK."

This derailment comes almost a year after an Amtrak train originating from Washington D.C. bound for New York City derailed in Philadelphia. Eight people were killed and more than 200 were injured in the May 12 crash. The exact cause of that crash is still under investigation, but authorities have said the train had been travelling twice the speed limit.
