51020 SP Sacramento 1974 Repaints, B-70-10, PCF 50' RBL Plt B 10-0 Offset Door, LD Bulkheads
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-foot 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-inch 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 SP was one of the few railroads that bothered to lower their brake wheels as well as all their ladders. We have created this faithfully.
Even though this series were rebuilt in some way with the lowering of the retaining valves to the car side and changing the manual slack adjustor to auto, they did not receive the more typical B-70-10-R class designation. Perhaps this classification was introduced after 1974?
