An Amtrak train on it's way from Washington D.C. to New York has derailed in Philadelphia, reportedly injuring more than four dozen people.

Emergency rescue crews were called to the chaotic scene in the Port Richmond section of the city approximately 9:35 p.m. Tuesday night where 8 to 10 cars of train #188 went off the tracks, reports. There were an estimated 238 passengers and 5 crew members on board at the time of the accident.

Sources say nearly 60 people are being treated for injuries at this hour at Temple University Hospital, Jefferson University Hospital, Hahnemann University Hospital, and Einstein Medical Center.

Fire Commissioner Derrick Sawyer tells he considers the derailment a 'mass casualty incident'.

All Amtrak service has been suspended between Philly and New York for the remainder of the evening.

The cause of the crash is unknown, but one passenger told Action News 'the train tilted over and rolled'. Amtrak said it plans to provide updates as more information becomes available and the scene is stabilized. The National Transportation Safety Board is currently investigating.
