A 1955 census found 154,907 shipping containers in use in non-Communist Europe. The number is large, but the containers were not: fully 52 percent of them were smaller than 106 cubic feet, less than the volume of a box 5 feet on a side. Almost all European containers were made of wood, and many had no tops; the user piled the goods inside and covered the load with canvas—hardly an efficient system for moving freight. The containers promoted by the Belgian national railway were meant to be slid up a ramp to fit inside truck bodies, requiring an extra stage of handling.
