Volkswagen and the Deutsche Bundesbahn developed an extremely creative idea when they signed a contract in 1959 for the rail transport of engines and transmissions between the individual Volkswagen production sites. The solution consisted of standardized containers that could be transported on short-coupled double units of converted stake cars of the RM(r)31 design. They now had only flat structures with wooden floor on which the sub-frames for the containers were mounted. Six containers filled with either 36 engines or 96 transmissions fit on each double unit. In 1966, the container carrying wagons for motor and transmission transport ran out between Hanover and Wolfsburg, Emden and Ingolstadt, as well as with the same destinations and later also to Brussels from Kassel-Baunatal. From 1970 onwards, Salzgitter, Neckarsulm, Stuttgart and Osnabrueck (Karman) were added as further destinations.
