NTSB: Braking system anomaly caused 2017 Upper Darby SEPTA crash

UPPER DARBY, Pennsylvania (WPVI) -- The National Transportation Safety Board has finished its years-long investigation into a 2017 SEPTA crash in Upper Darby, Pennsylvania.

The agency is blaming a "intermittent anomaly" in the braking system of the main car involved.

That train rear-ended another unoccupied car that was parked at 69th Street Terminal in Upper Darby back on August 22, 2017.

The operator and dozens of passengers were hospitalized at the time.
