PKP classification system is a system of assigning letters and numbers to series and individual locomotives used by the PKP - Polish national railroad operator.
The Deutsche Reichsbahn's Class 52 is a German steam locomotive built in large numbers during the Second World War. It was the most produced type of the so-called Kriegslokomotiven or Kriegsloks. The Class 52 was a wartime development of the pre-war DRG Class 50, using fewer parts and less expensive materials to speed production. They were designed by Richard Wagner who was Chief Engineer of the Central Design Office at the Locomotive Standards Bureau of the DRG. About a dozen classes of locomotive were referred to as Kriegslokomotiven; however, the three main classes were the Class 52, 50 and 42. They were numbered 52 1-52 7794. A total of 20 are preserved in Germany.
The history of rail transport in Poland dates back to the first half of the 19th century when railways were built under Prussian, Russian, and Austrian rule. Of course, "divided Poland" in the 19th century was the territory of the former Polish–Lithuanian Commonwealth and not that one of today's Republic of Poland. After Polish independence was declared on 11 November 1918, the independent Polish state administered its own railways until control was surrendered to German and Soviet occupiers during World War II.
PKP class Ok22 is a class of ordinary passenger (O) 4-6-0 (k) steam locomotive designed in 1922 for Polskie Koleje Państwowe. It was the first locomotive designed in Poland after World War I, so the design work was done jointly with Hanomag, based on the Prussian P 8
The Prussian Class S 3s were saturated steam locomotives developed by Hanomag for the Prussian state railways and were built from 1893.
The Prussian Class P 8 of the Prussian state railways was a 4-6-0 steam locomotive built from 1906 to 1923 by the Berliner Maschinenbau and twelve other German factories. The design was created by Robert Garbe. It was intended as a successor to the Prussian P 6, which was regarded as unsatisfactory.
Between 1934 and 1941 the Deutsche Reichsbahn (DRG) converted a total of 691 former Prussian-built Class 55.25–56 steam locomotives; the result was the DRG Class 56.2–8. The carrying axle enabled higher speeds and the engine could even be used as a passenger train locomotive. In addition the average axle load was lower, so that these locomotives could also be used on branch lines. The conversion entailed moving the boiler forward and raising it somewhat. The vehicles were given operating numbers between 56 201 and 56 891, although the numbering was not continuous.
The Prussian G 12 is a 1'E 2-10-0 goods train locomotive built for the Prussian state railways.
The Prussian Class P 6s were passenger locomotives operated by the Prussian state railways with a leading axle and three coupled axles.
The Prussian Class T 11 were passenger tank locomotives produced between 1903 and 1910 in the service of the Prussian state railways for duties on the Berlin Stadtbahn.
The kkStB 229 was a class of passenger 2-6-2 tank engines with the Imperial Royal Austrian State Railways, kkStB.
The Prussian state railways grouped a variety of different types of passenger tank locomotive into its Prussian Class T 5. Several examples of the sub-classes T 5.1 and T 5.2 transferred into the Deutsche Reichsbahn as DRG Classes 71.0 and 72.0.
The Prussian S 4's were German superheated express steam locomotives with the Prussian state railways, later grouped as DRG Class 13.5 in the Deutsche Reichsbahn. They were an evolutionary development of the Prussian S 3. The first locomotive was built in 1898 by Vulcan, Stettin as a modified S 3. She was the first superheated locomotive in the world. She was initially designated as Hannover 74 and towards the end as the S 4 Cassel 401. Two further trials locomotives appeared in 1899 and 1900 as Hannover 86 and Berlin 74 also classed as S 3's. They were later reclassified as S 4's Hannover 401 and Posen 401.
The Prussian Class G 5.1 steam engines were the first 2-6-0 goods locomotives in Europe. They were developed for the Prussian state railways from the Class G 4 and a total of no less than 264 units of this class were placed in service in Prussia between 1892 and 1902. The twin-cylinder G 5.1 had been designed to raise the speed of goods trains on main lines. In addition, more powerful engines were needed for the increasingly heavy train loads. The locomotives, which were equipped with a compressed air brake, were used in charge of fast goods trains (Eilgüterzugdienst) and also passenger trains due to their impressive top speed of 65 km/h. The G 5.1 was fitted with inside Allan valve gear and the carrying wheels were of the Adams axle design. The engines were coupled with tenders of Class pr 3 T 12. In Prussian service they were renumbered in 1905 into the 4001–4150 range.
PKP class Ol49 is a class of ordinary passenger (O) 2-6-2 (l) steam engine designed in 1949 and used in Poland by the Polskie Koleje Państwowe (PKP). A total of 116 were built between 1951 and 1954, 112 for the PKP and four for export to North Korea, by Fablok in Chrzanów.
The Fablok T3A also known as TKh49 or Ferrum 47 / 724 is a class of Polish steam industrial tank locomotive. It was built by Fablok in 1948-1961 years.
Px38-805, named Leon, is a preserved Polish 600 mm narrow gauge steam locomotive built by Fablok in Chrzanów, Poland. It was the only locomotive of PKP class Px38, and one of three built locomotives of Fablok W5A type.
The Prussian G 9 was the last saturated locomotive class developed for the Prussian state railways. A total of 200 were put into service between 1908 and 1911, first by Schichau, and later by other locomotive manufacturers. Since problems arose with the G 8, the superheated steam technology was not really trusted. The chassis was taken from the G 7, whereas the larger boiler was a new design. The G 9 remained inferior to the G 8 in terms of performance. At first a number of locomotives were referred to as G 7, but they were later reclassified G 9. They mainly operated in ore traffic between the Ruhr area and the North Sea.
PKP Class Pt31 is a Polish steam locomotive of Polskie Koleje Państwowe, designed for hauling heavy long-distance passenger trains, built in 1932-1940. The designation stood for fast passenger (P) 2-8-2 (t) steam locomotive designed in 1931.
