The Prussian Class S 3s were saturated steam locomotives developed by Hanomag for the Prussian state railways and were built from 1893.
The Class B XI engines of the Royal Bavarian State Railways were built between 1895 and 1900 by the firm of Maffei for deployment in Bavaria. The first delivery comprised 39 vehicles with two-cylinder, saturated steam operation, a further 100 two-cylinder compound locomotives followed in the period up to 1900.
The 36 locomotives of Class P 3/5 N of the Royal Bavarian State Railways were built between 1905 and 1907 by Maffei. The P 3/5 N evolved from the S 3/5 express train locomotive and had likewise a four-cylinder compound configuration. Compared with the S 3/5 the P 3/5 N had a smaller boiler but the same size cylinders. The P 3/5 N could haul a 350-ton train at 80 km/h on the level.
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 Württemberg Class K steam locomotives of the Royal Württemberg State Railways were the only twelve-coupled locomotives built for a German railway company.
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.
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 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.
After the Second World War, the Deutsche Reichsbahn in East Germany had a requirement for powerful goods train locomotives with a 15-18 tonne axle load for routes in the Mittelgebirge, the mountainous areas in the south of the country. As a result, the DR Class 58.30 emerged, as part of the so-called 'reconstruction programme', based on rebuilds of the former Prussian G 12 locomotives. Between 1958 and 1962, 56 locomotives, originally from various state railways were converted at the former repair shop, RAW Zwickau.
The Saxon Class XVIII was a German six-coupled tender locomotive built for the Royal Saxon State Railways in 1917/18 for express train services. The Deutsche Reichsbahn grouped them in 1925 into DRG Class 18.0.
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 Saxon Class VIb were four-coupled, tender locomotives in express train service with the Royal Saxon State Railways. In 1925, the Deutsche Reichsbahn grouped these engines into DRG Class 34.8.
The Prussian Class S 10 included all express train locomotives in the Prussian state railways that had a 4-6-0 wheel arrangement. There were four sub-classes: the S 10, S 10.1 and S 10.2.
The Prussian Class P 6s were passenger locomotives operated by the Prussian state railways with a leading axle and three coupled axles.
The Royal Saxon State Railways designated four-coupled, Atlantic (4-4-2) express locomotives as Class X and the Deutsche Reichsbahn subsequently grouped these locomotives into DRG Class 14.2 in 1925.
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 Mecklenburg Class P 4.2, formerly Class VII, were early German steam locomotives operated by the Grand Duchy of Mecklenburg Friedrich-Franz Railway and were used specifically for hauling express trains on the line from Warnemünde to Berlin. They were mechanically identical with the Prussian P 4.2. All 31 units were taken over by the Deutsche Reichsbahn who incorporated them as Class 36.6 with numbers 36 602–620 and 651–662. The first series of numbers were engines with a 14 t axle load, the second those with a 15 t axle load. In 1931 the last locomotive of this class was retired.
The Saxon Class IIIb was a twin-coupled tender locomotive built for passenger services with the Royal Saxon State Railways.
The Saxon Class VIII 2 was a twin-coupled tender locomotive procured for passenger services by the Royal Saxon State Railways. In 1925, the Deutsche Reichsbahn grouped these engines into their Class 36.9-10.
