PKP classification system

PKP classification system (Polish locomotive designation) is a system of assigning letters and numbers to series and individual locomotives used by the PKP - Polish national railroad operator. The system was introduced for steam stock by the Ministry of Railways on 3 November 1922, shortly after Poland regained her independence (1918), when the Polish railroads inherited a variety of German, Austrian and Russian steam locomotives, each with its own type convention. It was put into use in 1923–1926 years. The adopted solution allows telling the locomotive type (passenger/freight/mixed), wheel arrangement, origin and some other information from the type designation. After World War II a similar system was also adapted for diesel and electric locomotives.
