Significant quantities of dry beans are shipped using bulk rail hopper cars enabling 200,000‐pound net weight cargo to be efficiently transported with minimal handling from the point of origin at the elevator site to the end‐use processor. Beans are typically filled and discharged using conveyors and/or pneumatic air handling systems. Hopper cars must be thoroughly inspected prior to filling and are effectively sampled using standard probe procedures, subsequently assuring that hatch covers are secured and sealed prior to dispatching the load. The use of commercial 50‐foot box cars is suitable for direct loading of bagged beans for domestic and North American continental shipments. Large quantities of packaged beans are shipped within the domestic market using trucks of various capacities, e.g., vans, semitrailers (Roberston and Frazier 1978). It is a common practice to adjust the positioning of bags, totes, or tote boxes within the load to enable a uniform and stable cargo of appropriate weight distribution.
