The Ok22 series is a passenger train - Train Locomotive of the Polish State Railways PKP.
The construction of the Ok22 series was based on the Prussian P 8 . However, the locomotives received a more powerful boiler. This was installed much higher, which gave the construction a more modern, and for some railway enthusiasts, a strange look. The chassis was adopted unchanged from the original type.
The locomotives were developed by Polish engineers in cooperation with Hanomag in Hanover , which also delivered the first five locomotives to PKP in 1923. The other 185 locomotives were built by the Polish locomotive manufacturer Fablok in Chrzanów .
In 1939 the Ok22-132 with the Wilna area came to Lithuania and was classified by the Lithuanian State Railroad (LG) as K9 with the number 41.
During the Second World War , the Deutsche Reichsbahn classified the locomotives under the numbers 38 4501 to 38 4630. The former Polish Ok22-132, which was part of the armed forces, was not redrawn.
Ok22-23 in Jaworzyna Śląska and Ok22-31 were preserved as a museum locomotive in the Wolsztyn steam depot . The latter machine is owned by the Warsaw Railway Museum.
