The Prussian G 8.1 was a heavier, stronger development of the G 8 and was initially referred to as a 'strengthened standard class'.
The Prussian T 18 was the last class of tank locomotives developed for the Prussian state railways. They were originally intended for services on the island of Rügen as replacements for Class T 12 and T 10 engines. They emerged when a class of locomotive was conceived in 1912 that was to handle express and passenger trains in border areas or in shuttle services on short routes. A tank engine design with symmetrical running gear was envisaged because, unlike a tender locomotive, it could run equally fast forwards and backwards and could be operated on return journeys without having to be turned on a turntable. Its power and top speed were to be the same as those of the P 8. Robert Garbe designed this 4-6-4 (2′C2′) tank locomotive for 100 km/h with a 17-ton axle load and contracted the Vulkan Werke in Stettin to build it. It was given the designation T 18.
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 Mecklenburg T 3 was a German, goods train, tank locomotive built for the Grand Duchy of Mecklenburg Friedrich-Franz Railway from 1884. Originally designated as the Class XVII it had an 0-6-0T wheel arrangement and was based on the Prussian T 3.
The Oldenburg G 4.2 steam locomotives were goods train engines built for the Grand Duchy of Oldenburg State Railways between 1895 and 1909 in several series.
The Prussian G 12.1 was a German steam locomotive built for the Prussian state railways during the First World War and was the largest Prussian freight locomotive with a 2-10-0 wheel arrangement. It had three cylinders, the two outer ones driving the third axle and the inner one the second axle.
The Saxon Class III b were German steam locomotives built for the Royal Saxon State Railways in the late 19th century as tender locomotives for express train duties. In 1925, the Deutsche Reichsbahn incorporated the engines into DRG Class 34.77-78.
The Prussian G 5.4 was a German goods train locomotive with a compound engine. Due to its top speed of 65 km/h it was also used on passenger services. The G 5.4, like the G 5.3, differed from the G 5.1 and G 5.2 in having a shorter wheelbase and higher boiler pitch. In addition, the Krauss-Helmholtz bogies enabled its riding qualities to be improved, especially at higher speeds. Between 1901 and 1910 a total of about 760 vehicles of the Class G 5.4 were built for the Prussian state railways. The last 25 locomotives were fitted once again with an Adams axle.
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 steam locomotives of DRG Class 34.73, formerly the Mecklenburg Class P 3.1 were passenger train locomotives operated by the Grand Duchy of Mecklenburg Friedrich-Franz Railway and were based on the Prussian P 3.1. They were sometimes used in express train services to begin with. Of the 41 examples belonging to this administration, which were built between 1888 and 1908, two originally came from the Lloyd Railway (Neustrelitz-Warnemünde). One improvement over the Mecklenburg P 2 was the braked coupled axle.
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 T 9 was a class of German steam locomotive which included several types of tank engine, all with six coupled wheels and two carrying wheels operated by the Prussian state railways.
The Prussian Class T 3 steam locomotives procured for the Prussian state railways were 0-6-0 tank locomotives. Together with the Prussian T 2 they were the first locomotives that were built to railway norms. The first units were delivered by Henschel in 1882.
The Mecklenburg Class G 3 was an early German steam locomotive operated by the Grand Duchy of Mecklenburg Friedrich-Franz Railway. Formerly the Class IX it was a copy of the Prussian G 3.
The Prussian G 5.5's were early German freight locomotives with a compound engine. Unlike the otherwise identical G 5.4 they had a leading Adams axle instead of a Krauss-Helmholtz bogie. The delivery of the G 5.5 in 1910 followed directly on from that of the G 5.4. A total of either 20 or 25 G 5.5 were built.
The Mecklenburg Class G 4.2 operated by the Grand Duchy of Mecklenburg Friedrich-Franz Railway was a goods train, steam locomotive with a compound engine. It was procured between 1901 and 1905 from Henschel and Linke based on the Prussian G 4.2 prototype. A total of five machines were built for Mecklenburg. It was planned that they would be taken over by the Deutsche Reichsbahn and were to have been given numbers 53 401 to 53 405 according to the 1923 provisional DRG renumbering plan. But they were retired by 1924 before the final plan was issued.
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 4.2 was a class of compound 0-6-0 goods locomotive of the Prussian State Railways. It was a compound version of the G 3 and G 4.1 types by Henschel.
