The Prussian G 9 was the last saturated (i.e non-superheated) 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.
After World War I, 58 locomotives were ceded to Belgium (type 79), eight to Poland for the Polish State Railways (PKP), who classified them as Tp5, and one locomotive to the Saarland. [1]
133 locomotives passed to Deutsche Reichsbahn and were given the fleet numbers 55 2301 to 55 2433. Thirty-six of them were fitted with superheaters in the 1920s, which led to an increase in performance and speed. The locomotives that survived World War II were either retired (in the western zones by 1949, in East Germany as the last in 1961, 55 2361) or sold to private railways.
After 1945, the ČSD had two locomotives. They were designated as series 427.05. They originally came from Poland, part of PKP's Tp5 series. In 1947 they were returned to the PKP.
The locomotives were equipped with a Prussian 3-axle tender, type pr 3 T 12, to diagram sheet III-5b.
The Prussian G 8.1 was steam locomotive operated by the Prussian state railways. It was a heavier, stronger development of the G 8 and was initially referred to as a 'strengthened standard class'.
The Alsace-Lorraine Class G 8.1 was a superheated, goods train, steam locomotive with four driving axles, and was based on the Prussian G 8.1. There were no design differences between the two. The Imperial Railways in Alsace-Lorraine received a total of 137 G 8.1 engines between 1913 and 1919, of which eleven were built by Henschel and the rest by the Grafenstaden. They were numbered 5151 to 5278.
The Prussian G 10 was a German goods train, steam locomotive, whose design was based on a combination of the running and valve gear from the Prussian T 16 and the boiler from the Prussian P 8. In developing the G 10, however, the T 16 running gear with side play on the first and fifth axles was modified. The T 16 was also subsequently built with this modified configuration and called the Prussian T 16.1. The G 10 was intended for heavy goods train duties on main lines, but as a result of its low axle load it could be employed more flexibly than its equally powerful cousin, the Prussian G 8.1. The G 10 was occasionally even used in passenger train service.
In 1905 the Prussian state railways grouped six-coupled, medium-powered, goods train, tank locomotives into its Class G 3. In addition to standard locomotives, there were also 285 G 3s that were not built to German state railway norms, because they had been built, in most cases, before the foundation of the Prussian state railways.
The Prussian Class G 4 were German, six-coupled, goods train, steam locomotives with a boiler pressure of 12 bar, built primarily for the Prussian state railways. Classified by the state railway in 1905, they included 16 locomotives from the railway division of Mainz, that originally came from the Hessian Ludwigsbahn. These earlier locomotives were delivered between 1872 and 1896 and did not meet the Prussian norms.
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 G 7.1 engines of the Prussian state railways were German eight-coupled, goods train, steam locomotives.
The Prussian T 14s were German, 2-8-2T, goods train, tank locomotives operated by the Prussian state railways and the Imperial Railways in Alsace-Lorraine. They were later incorporated by the Deutsche Reichsbahn into their renumbering plan as Class 93.0–4.
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 G 8.3 was a 2-8-0, superheated, freight locomotive with three cylinders. It was developed to redress the lack of goods locomotives after the First World War. The inspiration to design a 2-8-0 locomotive based on the 2-10-0 Prussian G 12 came from Württemberg. The first vehicle was delivered in 1918. Compared with the G 12, the G 8.3 had one boiler shell and coupled axle fewer. After it had proved itself, a total of 85 examples of the G 8.3 were placed in service, all of which were taken over by the Reichsbahn, where they were numbered 56 101 to 56 185. No more were built thereafter because the G 8.2, with only two cylinders, was less costly to procure and maintain.
The Prussian Class G 8 locomotives were eight-coupled, superheated, freight locomotives operated by the Prussian state railways. There were two variants: the G 8 built from 1902 with a 14 tonne axle load and the "reinforced G 8" built from 1913 with a 17-tonne axle load. The latter was the most numerous German state railway (Länderbahn) locomotive, over 5,000 examples being built.
The Prussian G 8.2 class of locomotives actually incorporated two different locomotive types: one was the Prussian/Oldenburg G 8.2, for which the Deutsche Reichsbahn subsequently issued follow-on orders; the other was the G 8.2 of the Lübeck-Büchen Railway.
The Prussian Class T 12 were early German passenger tank locomotives built for the Prussian state railways in large numbers. These locomotives were superheated variants of the T 11.
The Prussian T 8 were six-coupled superheated goods tank locomotives of the Prussian state railways. They were originally intended for suburban passenger service in Berlin, and for use on branch lines. Due to their poor running qualities, they were demoted to shunting and short-distance goods train service.
The Prussian T 7 was a group of goods tank locomotives of the Prussian State Railways with an 0-6-0T wheel arrangement. It was not a class in the modern sense of identical locomotives.
The Prussian G 7.3 was a class of 2-8-0 locomotives of the Prussian state railways. The third class of the G 7 series, they were intended to power heavy goods trains on steep inclines, on which the permissible axle load was not yet that high. This affected for example, the Paderborn–Holzminden and Betzdorf–Siegen routes.
The Prussian G 7.2 was a class of 0-8-0 tender compound locomotives of the Prussian state railways. In the 1925 renumbering plan of Deutsche Reichsbahn, the former Prussian locomotives produced from 1895 to 1911 were given the class designation 55.7–13; while the locomotives of former Mecklenburgische Friedrich-Franz-Eisenbahn (MFFE) locomotives were classified as 55.57.
The Prussian G 5.3 was a class of 2-6-0 goods locomotives. They were the two-cylinder-simple version of the compound G 5.4. As with many Prussian locomotive design, simple and compound versions of the same type built. The G 5.3, like the G 5.4, differed from the G 5.1 and G 5.2 as it had a shorter wheelbase and a higher-pitched boiler. The Krauss-Helmholtz bogie was intended to improve the driving characteristics, especially at higher speeds. Production of the G 5.3 was from 1903 until 1906, and 206 units were built.
The Prussian G 5.2 was a class of two-cylinder compound goods locomotive introduced in 1895. As with many Prussian locomotive design, simple and compound versions of the same type were built – in this case the G 5.2 was the two-cylinder compound version of the simple G 5.1. The compound locomotives were more economical and more powerful than the simple locomotives; they were more suitable for long stretches with few stops. The newly introduced air brakes made it possible to use the G 5.2 on passenger trains, which the Prussian State Railways often did.
The Prussian G 4.3 was a class of 0-6-0 goods locomotive of the Prussian State Railways; they were manufactured between 1903 and 1907 by Union Giesserei in Königsberg. The type was developed with the aim of improving the running characteristics of 6-coupled locomotives. They proved a more capable design than the normal-type, and so had a higher maximum speed of 60 km/h (37 mph). However, they were quickly outclassed by increasing weight of freight trains.
