UPPER DARBY, Pa. — An out-of-service SEPTA Market Frankford Line subway train crashed into two other trains at the 69th Street Terminal just outside Philadelphia Tuesday morning, injuring four people and knocking seven cars off the track during the busy rush-hour commute, NBC Philadelphia reports.
The collision left the operator of the No. 57 train critically injured, while another operator and two passengers were also injured in the crash, but the injuries did not appear life-threatening.
