In April 1951, at Zürich Tiefenbrunnen railway station, the Swiss Museum of Transport and "Bureau International des Containers" (BIC) held demonstrations of container systems, with the aim of selecting the best solution for Western Europe. Present were representatives from France, Belgium, the Netherlands, Germany, Switzerland, Sweden, Great Britain, Italy and the United States. The system chosen for Western Europe was based on the Netherlands' system for consumer goods and waste transportation called "Laadkisten" (literally, "loading bins"), in use since 1934. This system used roller containers that were moved by rail, truck and ship, in various configurations up to a capacity of , and up to size. This became the first post World War II European railway standard UIC 590, known as "pa-Behälter." It was implemented in the Netherlands, Belgium, Luxembourg, West Germany, Switzerland, Sweden and Denmark.
