The German DRB Class 06 engines were standard steam locomotives ( Einheitsdampflokomotiven ) with the Deutsche Reichsbahn (DRB) designed to haul express train services. They were the only German locomotives with a 4-8-4 (Northern) wheel arrangement.
The two Class 06 locomotives built by the firm of Krupp in 1939 were the largest, heaviest and most powerful locomotives in the Deutsche Reichsbahn. They were built for heavy express train duties in hilly terrain. The performance requirement was for the transportation of 650 tons at 120 km/h (75 mph). On ramps of 1:100 it was to still be capable of maintaining 60 km/h (37 mph).
The Class 06 was given the same boiler as the Class 45 and many of the same components as the Class 41. The running gear, with four coupled axles, had a wheelbase of 6.75 m (22.1 ft)
In trials, the vehicles confirmed their remarkable capability and running qualities. However the locomotives tended to derail in tight turnout curves. And, like the Class 45s, the boilers developed cracks, leaky tubes and popped stay bolts, so that the locomotives were unconvincing when hauling measurement vehicles or scheduled trains.
As a result of the war no more were produced. After World War II a locomotive of this size was no longer needed, thus neither the necessary structural modification of the engines was carried out, nor did any follow-on orders result. Both engines were seen as having a faulty design and were retired by the Deutsche Bundesbahn in 1951 in Frankfurt am Main and scrapped, because the DB refused to replace their boilers.
The two locomotives, which had operating numbers 06 001 and 06 002, were equipped with 2'3 T 38 St tenders.
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 Deutsche Reichsbahn's Class 52 is a German steam locomotive built in large numbers during the Second World War. It was the most produced type of the so-called Kriegslokomotiven or Kriegsloks. The Class 52 was a wartime development of the pre-war DRG Class 50, using fewer parts and less expensive materials to speed production. They were designed by Richard Wagner who was Chief Engineer of the Central Design Office at the Locomotive Standards Bureau of the DRG. About a dozen classes of locomotive were referred to as Kriegslokomotiven; however, the three main classes were the Class 52, 50 and 42. They were numbered 52 1-52 7794. A total of 20 are preserved in Germany.
The Deutsche Reichsbahn's Class 05 was a German class of three express passenger steam locomotives of 4-6-4 wheel arrangement in the Whyte notation, or 2′C2′ h3 in the UIC notation used in continental Europe. They were part of the DRG's standard locomotive (Einheitslokomotive) series.
The DRB Class 50 is a German class of 2-10-0 locomotive, built from 1939 as a standard locomotive (Einheitsdampflokomotive) for hauling goods trains. It had one leading axle and five coupled axles and was one of the most successful designs produced for the Deutsche Reichsbahn.
The Class S 3/6 steam locomotives of the Royal Bavarian State Railways were express train locomotives with a 4-6-2 Pacific or 2'C1' wheel arrangement.
The Prussian Class P 8 of the Prussian state railways was a 4-6-0 steam locomotive built from 1906 to 1923 by the Berliner Maschinenbau and twelve other German factories. The design was created by Robert Garbe. It was intended as a successor to the Prussian P 6, which was regarded as unsatisfactory.
German Class 45 steam locomotives were standard locomotives (Einheitslokomotiven) designed by the Deutsche Reichsbahn for hauling goods trains.
The German Class 41 steam locomotives were standard goods train engines (Einheitslokomotiven) operated by the Deutsche Reichsbahn (DRB) and built from 1937 to 1941.
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 German Class 03.10 engines were standard steam locomotives (Einheitsdampflokomotiven) belonging to the Deutsche Reichsbahn and designed for hauling express trains.
The Einheitsdampflokomotiven, sometimes shortened to Einheitslokomotiven or Einheitsloks, were the standardized steam locomotives built in Germany after 1925 under the direction of the Deutsche Reichsbahn-Gesellschaft. Their manufacture made extensive use of standard design features and components.
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 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 kkStB 112 was a class of express train 2-2-2 tank engine operated by the Imperial Royal Austrian State Railways.
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 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 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 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.
