These 40’ box cars with plug doors are painted brown with black and white Keystone logos and white lettering. They were built in March 1960 and run on Bettendorf trucks. One hundred of these cars were equipped with the Pullman-Standard “Compartmentizer” loading device and marked “PC” in yellow on their doors. Also equipped for application of heaters, the weight of the insulation and the loaders were such that the nominal capacity of these cars was reduced to 95,000lbs
