The Deutsche Reichsbahn-Gesellschaft's BR 01 steam locomotives were the first standardised (Einheitsdampflokomotive) steam express passenger locomotives built by the unified German railway system. They were of 4-6-2 "Pacific" wheel arrangement in the Whyte notation, or 2′C1′ h2 in the UIC classification. The idea of standardisation was that it would reduce maintenance costs; i.e. if a BR 01 whose engine shop was in, say, Berlin broke down in Dresden, instead of having to ship the necessary part from Berlin and take the locomotive out of service, a part from the Dresden shop could be used as all of the engines, parts, and workings were exactly the same and produced nationwide. Thus it was a "standard" product for engine shops.
The DB Class 66 was a class of two Deutsche Bundesbahn (DB) locomotives designed for fast goods train and passenger train services on the main and branch lines of Deutsche Bundesbahn (DB), the national railway of the former West Germany.
The Bavarian Class D XII steam locomotives were manufactured by the firm of Krauss from 1897 for the Royal Bavarian State Railways. Ninety six of them were procured for service on the stub lines running from Munich into the mountains, but in reality they were stationed in many large Bavarian locomotive depots. Two engines were transferred to the Palatinate Railway (Pfalzbahn) in 1916, the remaining 94 later joined the Deutsche Reichsbahn fleet and were incorporated as DRG Class 73.0-1 with operating numbers 73 031–124.
The six-coupled P 5 of the Palatinate Railway (Pfalzbahn) was to replace the four-coupled locomotives in the Palatinate. They were given a leading Krauss-Helmholtz bogie and a trailing bogie in order to achieve satisfactory weight distribution.
The Class 62 engines were standard passenger train tank locomotives of Germany's Deutsche Reichsbahn-Gesellschaft (DRG).
The DRG Class 89.0 was a goods train tank engine of standard design built for the Deutsche Reichsbahn (DRG).
The two German DRG Class 61 steam engines were express train locomotives specifically built by Henschel for the Henschel-Wegmann train in service with the Deutsche Reichsbahn. The Henschel-Wegmann train was an initiative of the German locomotive construction industry, intended to be able to demonstrate a powerful steam locomotive-hauled train alongside the emerging express diesel multiple units, such as the Hamburg Flyer.
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.
The German DRG Class 95 are ten-coupled tank locomotives with a 2-10-2 wheel arrangement, which were procured by the Deutsche Reichsbahn in 1922 for hauling heavy goods trains on steep main lines. Because the development of this class was started by the Prussian state railways, it was designated as the Prussian Class T 20.
The DR Class 65.10 was a class of 2-8-4 passenger train tank engine operated by the East German Deutsche Reichsbahn (DR) for heavy suburban and commuter services.
The engines of DR Class 99.23 are metre gauge tank locomotives, that were procured by the Deutsche Reichsbahn (DR) in East Germany from 1954 to 1956. When they entered service they had operating numbers 99 231–99 247. Today they are numbered 99 7231–99 7247.
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 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 Saxon Class XIV T locomotives were six-coupled tank engines operated by the Royal Saxon State Railways for mixed duties on main and branch lines. In 1925, the Deutsche Reichsbahn grouped them into their DRG Class 75.5.
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 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 kkStB 30 were a class of 2-6-2T locomotives designed by Karl Gölsdorf for use of the Vienna Stadtbahn of the Imperial Royal Austrian State Railways. They were specifically designed for use on the inner-city routes of the Vienna Stadtbahn, where they hauled trains of up to ten of the Stadtbahn's 4-wheeled carriages. They were built by Lokomotivfabrik Floridsdorf, Wiener Neustädter Lokomotivfabrik and Lokomotivfabrik der StEG between 1895 and 1901.
The Saxon Class VII T were twin-coupled tank engines of the Royal Saxon State Railways designed for branch line (Sekundärbahn) operations. In 1925, the Deutsche Reichsbahn grouped these locomotives 1925 into their Class 98.70.
The class IV h (four-h) locomotives of the Grand Duchy of Baden State Railway (German: Großherzoglich Badische Staatseisenbahnen, G.Bad.St.E.) were express locomotives with a 4-6-2 (Pacific) wheel arrangement. They later passed to the Deutsche Reichsbahn, who classified them as class 183.
