The Polish State Railways (PKP) used several classes of Prussian and other German locomotives. The most significant of these was the Prussian P 8, classified in Poland as the PKP class Ok1. After the First World War, Poland received as reparations and also bought altogether 257 of these locomotives. After the Second World War, their number rose to 429 locomotives, which made it the most numerous passenger locomotive in Poland. A few were preserved and kept in working condition, including Class Ok1 No. 359. (Also see Germany - Prussia)
