On January 4, 2017, at 12:47 p.m., eastern standard time, SEPTA trolley car 9101, with 41 passengers, was traveling north on trolley route number 10 when it stopped at the southeast corner of Lancaster Avenue and 38th Street, Philadelphia, Pennsylvania, to offload passengers. SEPTA trolley car 9085, with five passengers, traveling in the same direction, collided with the rear of the stopped SEPTA trolley car at an estimated speed of 11 miles per hour (mph). Emergency responders transported both operators and 46 passengers to local hospitals for nonlife-threatening injuries. Follow-up brake testing identified the failure of the emergency brake push-button electrical switch to activate the track brake. Although the trolley operator in this accident activated the track brake by using the foot pedal instead of the push-button electrical switch, the circumstances of this switch failure could contribute to accidents or incidents on other trolley or rail transit vehicles across the United States with similar emergency brake electrical switch designs.
TO THE FEDERAL TRANSIT ADMINISTRATION: Utilize your authority under Title 49 Code of Federal Regulations 670.25, and issue a general directive that would require all state safety oversight agencies to direct rail transit agencies to periodically test the performance of all of their rail transit vehicle braking systems to detect potential latent system failures.
