Two construction workers were killed when an Amtrak train traveling from New York to Savannah, Ga., Sunday struck a backhoe that was on the tracks about 15 miles south of Philadelphia.
The crash derailed the lead engine of Palmetto Train 89, according to a statement by Amtrak.
Amtrak said initial reports were that some passengers were being treated for injuries, but could not immediately confirm fatalities.
A passenger on the train described a fireball and windows on the train being blown out upon impact.
The derailed Amtrak train, which was carrying 341 passengers and 7 crew members, forced Amtrak to suspend service on the Northeast Corridor and SEPTA to suspend its Wilmington/Newark regional rail service.
Local emergency responders were on the scene and the crash is being investigated.
