In 1959 Pacific Car & Foundry (PC&F) worked with Southern Pacific to design and develop a new series of cars, Insulated Boxcars or RBLs. They started with centered 9' doored cars in a Plate B clearance for the canned and food stuffs trade that was needed on a majority of SP and it's subsidiary SSW's service areas. As the design developed over 3 years, in late 1962 a 10-foot offset doored design was designed. Which is the subject of this model.
The entire upper body of the boxcar was riveted together from the bottom sill up, in the 6+5 R pattern. Whereas the underframe was fully welded. These were insulated, had proven 20" cushioned underframes, usually Hydra-Cushion cushioning devices. Many types and configurations and combinations of loaders were used as per customer specifications, but these specifically had LD Bulkheads loaders. Also note that SSW was one of the few railroads that bothered to lower their brake wheels as well as all their ladders.
