The 33’ twin bay rib side open hoppers are painted Freight Car Red with white Circle Keystone logos and white lettering. They were built in March 1942 and run on Bettendorf trucks. Part of class H-31, these hoppers were members of series 220300-220841 built by the Pennsylvania Railroad at the Altoona Shops. Class H-31 hoppers had a capacity of 1859 cuft, with a load limit of 129,700. PRR kept the circle keystone logo until the mid-1950s when it decided in favor of the shadow keystone without the circle.
