The most powerful freight locomotive designed and built for Königlich Preußische Eisenbahnverwaltung (Prussian state railways, KPEV), was three-cylinder Decapod G12. This type remained in production between 1917 and 1921, 1509 examples being delivered by eight manufacturers. After the war a ‘scaled-down’ variant was proposed by Henschel, with shortened boiler and 1-4-0 axle arrangement. The idea was to develop a modern replacement for older medium freighters, many of which had to be handed over to foreign railway managements as a part of war reparations. Such locomotive finally emerged as class G83, with prototype (s/n 16443) being outshopped in 1919.

Although the design was basically successful, the very idea of producing a three-cylinder medium freighter was not particularly favored by KPEV, who tended to value simplicity of manufacturing and maintenance. It was soon found that cheaper and less complex two-cylinder locomotives could do the same job. Such engine, classed G82, was also developed from G12 and remained in production until 1930, with almost 1,000 examples built. Production run of class G83 was much shorter, only 85 engines being built between 1919 and 1920, all by Henschel. Later they were classed 561. After WWII most of them (62) went to Eastern Germany, remaining there in use until late 1960s. Four remained with DB, but between 1946 and 1948 were sold to Osthannoversche Eisenbahnen and immediately rebuilt into a two-cylinder variant; the last one was withdrawn in 1964. One example became Soviet war booty and the fate of two is unknown. PKP took over sixteen examples, classed Tr3. These complex locomotives found little favor with Polish railwaymen and their service was comparatively short: the last one, Tr3-16 (ex 56 181, Henschel 17183/1920) was written off in June 1955. Five were handed over to industry. Not a single example of this locomotive has been preserved.
