01History
Introduction
The first five engines were built in Germany by Hanomag in 1923. Polish production started in 1928 and lasted until 1934 after which 185 locomotives had been manufactured by Fablok in Chrzanów. The first Polish-built locomotive (Ok22-6) was ready on December 31, 1928. Polish versions of the locomotive bore some improvements and changes compared with German ones, and were similar to PKP class Ty23. Ok22 locomotives were the first on the PKP to be equipped with electric lights.
Wartime
After the German invasion of Poland in World War II, most Ok22 locomotives were taken into the Deutsche Reichsbahn fleet as 38 4501 to 38 4630.
Present day
Only two examples have survived. Ok22-23 in Jaworzyna Śląska and Ok22-31 in Wolsztyn. Ok22-31 was an operational engine. It ran until 1997, and after retirement became a stationary exhibit. In 2004 the machine was restored to working order again, and it ran until 2009. It is currently static.
