Ok, closeProduction of new express steam locomotives of Pt47 series undertaken in 1948 at the first locomotive factory in Poland in Chrzanów and at Hipolit Cegielski Manufacturing Company in Poznań was based on a modified pre-war documentation of Pt31 locomotive, designed by the Fablok Design Office under engineer Kazimierz Zembrzuski. Introduced constructional changes resulted from technical progress and unification with the series of Ty45 freight locomotives which was built at the same time. Between 1948-1951 the Polish State Railways received 180 new locomotives of Pt47 Series (120 manufactured by Fablok and 60 by Hipolit Cegielski Manufacturing Company), which were delivered to the locomotive shed. Like its prototype, the Pt47 series turned out to be perfect for its assigned tasks. As part of the modernization process, the majority of locomotives equipped with a mechanical coal feeders which eliminated the physical effort in handling the furnace. Steam locomotives were still intensively exploited to the end of the 80's. The Pt47-104 locomotive exhibited at Stacja Muzeum was deleted from the Polish State Railways inventory at Rozwadów locomotive shed on 4 May 1989.
