what is it?
Ok1 is the Polish designation of a Prussian steam locomotive, the Prussian P 8, used on Polish State Railways. Production of the P 8 lasted from 1908 until 1928 and this locomotive was used on practically all European railway lines. After the end of World War I, 192 Class P 8 engines were handed over as a reparation to Poland, including two machines for Free City of Danzig, where they were re-designated as Class Ok1 locomotives (numbers: Ok1-1 to Ok1-190 and Ok1-1Dz and 2Dz for Danzig machines).
