Out of the great curve between Merion and Narberth stations on Pennsy's electrified Main Line west of Philadelphia, symbol freight P-9, a Camden, NJ to Enola, PA run, is led by E-44 electrics 4442 and 4459 with 126 cars, including a new X-58 PRR box first out. There were still plenty of forty foot refrigerator and box cars in the freight car fleet at this time.
