Twentieth Street Shops

        This is the Twentieth Street Shops just before the onslaught of diesels. One diesel does appear in the photo spotted in Yard A. (Locomotives are not parked, they are spotted.) There is a J1 on the turntable and about twenty steam locomotives around the servicing facilities and just east of the roundhouse. That does not count the many locomotives stored in the Chase Avenue Yard. Steam still ruled on the Pennsy when this photo was taken.
