The German Railway Company (Deutsche Bundesbahn) ordered the first group of smaller switcher locomotives in 1932. These switcher locomotives were divided into two different performance groups. The first performance group was a group of smaller switcher locomotives with an engine power of 39 hp. The second performance group was a group of the switcher locomotives with an engine power of 40 hp. The small switcher locomotives of performance group II, also known as the Köf II, were mainly designed for the shunting of small freighter trains at the small-scale train stations in Germany. Their low weight and their low power made them ideal for this type of work. Up until 1974, these small switcher locomotives were delivered to Germany. This Lego locomotive is built after the Baureihe 323 model, owned by the German Railway Company.
