Two people were killed and 35 others injured when an Amtrak train derailed early Sunday in Pennsylvania, prompting officials to shut down service along a busy stretch of the northeast corridor.
Chester Fire Commissioner Travis Thomas said the two killed were not passengers aboard the train.
Amtrak officials says none of the 35 passengers being treated have life threatening injuries.
News reports say the train was travelling from New York to Savannah, Georgia, when it struck a backhoe on the tracks, just outside of Philadelphia at 8 a.m., killing two construction workers.
The accident caused the lead engine to derail. The train was carrying some 350 passengers and crew at the time.
Amtrak said it was temporarily suspending train service on the Northeast Corridor between Wilmington, Delaware and Philadelphia, Pennsylvania.
Officials from the National Transportation Safety Board and the Federal Railroad Administration are investigating the incident.
