An Amtrak passenger train crashed into a backhoe on the track near Philadelphia, killing two construction workers for the railroad service, a source close to the investigation said.
The crash which occurred on Sunday morning also left 35 people injured, the Chester Fire Department said.
It’s unclear why the backhoe was on the track near Chester, just south of Philadelphia.
The two fatalities were found on or near the backhoe, Pennsylvania Emergency Management spokeswoman Ruth Miller said.
The train was carrying about 341 passengers and seven crew members when it crashed, Amtrak said.
The impact caused the lead engine of the train to derail.
Amtrak said it was providing limited service between Philadelphia and Wilmington, Delaware, as the Federal Railroad Administration and National Transportation Safety Board investigate.
The crash came less than a month after an Amtrak train headed from Chicago to Los Angeles derailed in Kansas, injuring 32 people.
It also came almost a year after another Amtrak derailment near Philadelphia which left eight people dead and more than 200 injured.
