From June 1947, when Pull-


man-Standard produced its first PS-1 boxcar for Lehigh Valley, through 1963, the PS-1’s design was predicated on several things. The inside post cars had Pull- man’s proprietary ends and roof. That all changed in 1960 when the Southern came calling, re- questing a huge change in the par- adigm. That year, Pullman-Stan- dard built 200 cars with flat ends, 24 external posts per side, and a flat-pan- eled roof (lot 8573). It would seem that Southern’s


engineer-


ing department engi- neered and supplied the design to Pullman- Standard. (At the time, Pullman-Standard was heavily into mass-pro- duced


standardized


cars, so the South- ern’s influence must have been consider- able.) In addition, the cars were Southern’s first class with the Hy- droframe-60 cushion

underframe (an invention de- rived from the collaboration of Southern Railway and the Frank- lin Institute of the University of Pennsylvania). Apparently, the Southern was


pleased with the car’s design be- cause the railroad procured a follow-up order in 1963 that in- corporated many elements of the prior order. This leads us to the focus of this three-part series on

these follow-up orders for “non- standard” PS-1 boxcars. Pullman accommodated its (very) impor- tant on-line customer with lot 8694, which was built in June and July 1963. Pullman also fabricated a separate order (lot 8776) in March and April of that year to be equipped with 10-foot Camel plug doors. Later that year, Southern subsidiary Central of Georgia received 200 similar cars
