The PKP series PT31 was a fast train - Train Locomotive of the Polish State Railways (PKP).

history

After its founding in 1918, PKP had over 160 different types of locomotives from Germany, Austria, Russia, Hungary and the USA. Similar to the development of standard locomotives in Germany, specifications for standard locomotives were also drawn up in Poland. They only provided for superheated steam locomotives in two-cylinder design with simple steam expansion. The Pt31 was developed based on these standards for heavy express train service.

Between 1932 and 1939 Fablok in Chrzanów built a total of 98 locomotives under the direction of Kazimierz Zembrzuski, one of the leading Polish locomotive designers at the time. In 1939, 92 Pt31 specimens were listed in the PKP's inventory. The remaining six may have been exported or scrapped.

After the occupation of Poland, 54 Pt31s were in German and 36 Pt31 in Soviet ownership. Two Pt31s appeared in Romania. Another twelve Pt31s were built in Chrzanów in 1940 for the Deutsche Reichsbahn . These twelve machines were initially operated by the Deutsche Reichsbahn as the 39.10p class, but were redesigned as 19 155 to 166 in October 1941. In the redesignation plan of 1942, the 19.1 series was specified for the Pt31 and the older locomotives were consequently classified as 19 101 to 154. In addition, after the start of the Russian campaign, 14 more Pt31s than 19 167 to 180 were added to the holdings of the Deutsche Reichsbahn.

Most of the machines incorporated into the German Reichsbahn were used in Austria during the Second World War, where they demonstrated their high performance, which is why they were more popular with Austrian locomotive staff than the German 03.10 series, which can also be found in Austria.

After the Second World War , the Pt31s were scattered all over Central Europe. Seven locomotives remained in West Germany that belonged to the Treuchtlingen and Hof depots until 1950 . In 1955 13 machines returned to Poland from the GDR. Another 16 locomotives came back from Hungary and Czechoslovakia. Most of the locomotives used in Austria were confiscated by the Soviets as foreign locomotives after the war and ultimately returned to Poland. Only three units from the year of construction 1940 remained with the ÖBB as the 919 series , namely the 919.158, 919.165 and 919.166. The 1D1 locomotives were used on the Western Railway and later on the Southern Railway between Vienna and Gloggnitz. After they were electrified, the machines were collected and scrapped by a decision of July 5, 1961 .

Four locomotives were classified as class 488.05 by the Czechoslovak State Railways (ČSD).

Today, on the one hand, the Chabówka Pt31-64 railway depot (owned by the Warsaw Railway Museum) can be seen as the penultimate locomotive retired in February 1978; on the other hand, the Pt31-49 exists as the last decommissioned copy of its series (z-position Feb. 1980) in unfortunately very deplorable condition in the Jaworzyna Śląska Railway and Technology Museum (formerly Königszelt ).

In 1989 the Pt 47-138 was imported from Poland to Austria by the Brenner & Brenner steam locomotive operating company . It was overhauled, adapted to the external appearance of the Pt31 series and now runs special trains under the designation 919.138.
