The Prussian Class S 3s were saturated steam locomotives developed by Hanomag for the Prussian state railways and were built from 1893.
The first steam locomotives of the Baden Class VI c were delivered in 1914 by the Maschinenbau-Gesellschaft Karlsruhe for service in southwestern Germany with the Grand Duchy of Baden State Railway.
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 Class G1s were German steam locomotives procured by the Grand Duchy of Oldenburg State Railways from 1867 to 1877. They were intended to work both as tank engines as well as with a tender.
The Oldenburg T 2 steam locomotives were German 0-4-0 tank engines built between 1896 and 1913 for the Grand Duchy of Oldenburg State Railways. They were designed for use on branch lines. A total of 38 units were produced, based on a Prussian T 2 prototype and differing only in the boiler fittings. Unlike their Prussian cousins, they had no steam dome and the regulator was located in the smokebox. Its permitted top speed of 50 km/h was also higher than the Prussian version.
The steam locomotives of Oldenburg Class P 4.1 were German locomotives built for the Grand Duchy of Oldenburg State Railways between 1896 and 1902. They were based on a Prussian P 4.1 prototype and a total of 19 engines were procured up to 1902. Overall the Oldenburg engine was less powerful than its Prussian counterpart, because the grate area was smaller and the steam dome was omitted. The regulators was housed in the smokebox. The Deutsche Reichsbahn took them over in 1920 and allocated them numbers 36 1201 to 36 1219. They were retired in the 1930s.
The Oldenburg Class S 5 steam engine was a German locomotive built for the Grand Duchy of Oldenburg State Railways between 1909 and 1913. It was based on the Prussian S 5.2 and, like its predecessor, the Class S 3, it was procured for the route between Wilhelmshaven, Oldenburg and Bremen.
The Oldenburg Class P 4.2 steam locomotives were German engines built for the Grand Duchy of Oldenburg State Railways between 1907 and 1909. They were based on the standard variant of the Prussian P 4.2, but there were a number of small differences such as a Ranafier steam dryer and, on three examples, a Lentz valve gear, a system widely used in Oldenburg. Production began in 1907 and eight engines were procured up to 1909.
The Oldenburg Class S 3 steam locomotive was a German engine built for the Grand Duchy of Oldenburg State Railways in 1903 and 1904. It was based on a Prussian prototype, the Prussian S 3, and procured for the route between Wilhelmshaven, Oldenburg and Bremen. It was the first express train engine built for the Oldenburg state railways and also the first one fitted with a steam dome. It replaced the old P 4 passenger train locomotives.
The Oldenburg G 7 steam locomotive was a German 0-8-0 locomotive produced for the Grand Duchy of Oldenburg State Railways. It was an eight-coupled engine, intended for heavy goods train duties, and was based on the Prussian G 7. It had a 1,660 mm diameter boiler located 2,820 mm above the top of the rails in the plate frame, and was equipped with a single Walschaerts valve gear as well as a Lentz valve gear. Thirteen were taken over by the Deutsche Reichsbahn, grouped into DRG Class 55.62 and given numbers 55 6201–55 6213.
The Prussian T 13 was a series of tank locomotives built in large numbers for the various German state railways, notably the Prussian state railways, and the Deutsche Reichsbahn during the early part of the 20th century.
The Oldenburg Class T 5.1 was a German steam locomotive built for the Grand Duchy of Oldenburg State Railways as a tank engine for passenger train duties. Its design was based on that of the Prussian T 5.1.
The express train locomotives of Oldenburg Class S 10 were built for the Grand Duchy of Oldenburg State Railways for duties on the Bremen–Oldenburg–Wilhelmshaven line, which was the most important express route in Oldenburg. They were amongst the few locomotives of this railway company that were not based on those of the Prussian state railways, because the light railway track dictated that they had to have an average axle load of no more than 15 t which was lower than that on comparable Prussian vehicles.
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 steam locomotives of Oldenburg Class B of the Grand Duchy of Oldenburg State Railways were built in the early 1900s for working the metre gauge network on the German island of Wangerooge.
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 Oldenburg Class T 1 was an early German locomotive operated by the Grand Duchy of Oldenburg State Railways. It was a four-coupled tank locomotive for shunting duties. There were two types, of which the later one entered the Deutsche Reichsbahn fleet and became Class 98.74.
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 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.
