It happened at 7:11 a.m. Tuesday as a northbound train approached the Ellsworth-Federal station. Police say a 17-year-old girl fell on the tracks, and the train rolled over her foot.
She was rushed to the hospital in critical condition with leg and foot injuries.
Investigators believe her fall was accidental, and foul play is not suspected. Police say the engineer saw her fall, but couldn't stop the train in time.
Power was cut immediately, and trains by-passed the station.
Commuter Al Williams arrived at the station, planning to take the Broad Street Line to an appointment.
But when he arrived, buses were running instead of the train, and police and the fire department were on the scene.
"The police basically had everything in lockdown," said commuter Al Williams.
Police cleared the scene around 8:45 a.m.
SEPTA does have video of the incident, which they are reviewing as part of this investigation.
