One of the first Polish-made locomotives after Ist World War was Ok22-class, which design was based on German P8 (in PKP named Ok1). The design occured to be great success and many Ok22s were in service till final withdrawal of the steam locomotives in mid-eighties. Picture shows Ok22-31, working as shunter in Wolsztyn.
