These 60'-0" insulated box cars were built by PC&F in 1968. They featured 5583 ft3 capacity, Hydra Cushion underframes, two-piece bulkheads, adjustable side fillers, and a 10"-0" plug door.
Note that the truck spacing is wider on this class compared to the very similar B-100-12 class cars.
Many of these cars were rebuilt as B-100-18R class cars.
