WASHINGTON - Multiple people were injured Tuesday after an Amtrak train derailed near Philadelphia, with up to 10 cars rolling over, US media reported.
At least one of the metal trains was bent in an L-shape. Dozens of emergency personnel used flashlights to comb the area for survivors after dark. They used ladders to climb over the flipped trains.
The Philadelphia Fire Department said the Washington to New York northbound train derailed. NBC television reported that many were injured.
It was a regional train, according to an NBC television producer who was a passenger. Train 188 was scheduled to leave Washington at 7:10 pm (2310 GMT) and arrive in New York at 10:34 pm.
There are no seatbelts on Amtrak trains.
The National Transportation Safety Board said it was gathering information about the derailment.
Former US Congressman Patrick Murphy of Pennsylvania was on the train.
" Im ok. Helping others. Pray for those injured," he tweeted.
Murphy, who was on board the cafe car, said the train seemed to be going 60-70 miles (97-113 kilometers) per hour when it suddenly derailed and rolled.
Some of the injured -- many with bloodied hands and faces -- were unable to move, Murphy said.
