Abstract
A stack supporting container car includes a plurality of car units interconnected by articulating connector with the end units provided with conventional railroad couplers. Each car unit includes side sills and body bolsters supported on trucks. The side sills and body bolsters are spaced apart sufficiently to allow the bottom portion of a short lower container to pass therethrough with the weight of the stack of containers being supported only by four corner feet connected to and projecting below the side sills. Bulkheads with fixed side and end container restraining walls and with movable corner engaging mechanisms are provided on the car unit to selectively restrain either a short or a long container supported upon the lower container in transport position on the car unit. The upper and lower surfaces of containers provide ample clearance to safely move over the rails and under bridges or the like.
