Federal officials are investigating a commuter rail crash outside of Philadelphia that left dozens injured early Tuesday morning.
A Southeastern Pennsylvania Transportation Authority (SEPTA) train slammed into an unoccupied train that was parked at a terminal in Upper Darby, Pa., injuring 42 people, according to multiple reports.
Four people were critically injured, according to SEPTA, with some passengers describing a “bloody scene” to local news outlets. The conductor of the train was among those injured but was treated and released from the hospital.

A National Transportation Safety Board (NTSB) team is now on the scene investigating, along with local authorities.
It’s unclear what caused the crash. The NTSB is expected to provide updates at a briefing later in the day Tuesday.
Trains have resumed normal operation, but passengers can still expect some delays in the area.
Earlier this year, four people were injured at the same terminal when multiple SEPTA cars collided.
