The two German Class 04 steam locomotives were experimental engines with the Deutsche Reichsbahn, that were derived from the Class 03 standard locomotives ( Einheitsloks ).
In 1932, the Deutsche Reichsbahn tried to raise boiler overpressures from 156.9 to 245.1 N/cm2 (227.6 to 355.5 psi) by using high-tensile steel. These engines, built by the firm of Krupp, were initially tested at the Grunewald Locomotive Testing Office. With a specific steam consumption value of 5.2 kg/PSh with respect to their indicated output, the locomotives clearly undercut the very low steam consumption value of the Class 03 by over 1 kg/PSh. The coal consumption based on the effective power at the coupling hook, was 0.96 kg/PSh compared with 1.13 kg/PSh on the 03. [1]
The medium-pressure boilers did not prove to be stable, and after a short time damage occurred to the firebox. Since the locomotives did not meet expectations even after modifications and repairs, the permissible boiler overpressure was finally reduced to 20 atmospheres in 1935 and they were added to the operating portfolio with the company numbers 02 101 and 02 102. They were then intended to be used in regular train service from the Hamburg-Altona depot, but since they had no experience with four-cylinder compound locomotives there, they were handed over to the Hof depot in 1936. Due to a lack of water, the boiler of 02 101 exploded on 3 April 1939, [2] whereupon both engines were decommissioned and were scrapped in 1940.
The engines were equipped with a 2′2′ T 32 standard tender.
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 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 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.
The Deutsche Reichsbahn had a standard passenger train tank engine with a wheel arrangement of 1'C1' or 2-6-2 and a low axle load, which was designated in their classification system as the DRG Class 64. The Class 64 was developed from 1926 onwards and it was built between 1928 and 1940. Many German manufacturers contributed to the series.
German Class 45 steam locomotives were standard locomotives (Einheitslokomotiven) designed by the Deutsche Reichsbahn for hauling goods trains.
The Class 44 was a ten-coupled, heavy goods train steam locomotive built for the Deutsche Reichsbahn as a standard steam engine class (Einheitsdampflokomotive). Its sub-class was G 56.20 and it had triple cylinders. It was intended for hauling goods trains of up to 1,200 tonnes on the routes through Germany's hilly regions (Mittelgebirge) and up to 600 tonnes on steep inclines. They were numbered 44 001-44 1989.
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 DRG Class 71.0 was a 2-4-2T locomotive with the Deutsche Reichsbahn, which was intended as a replacement for railbuses. Originally it had been planned for these standard engines (Einheitsloks) to haul fast passenger trains.
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 G 12 is a 1'E 2-10-0 goods train locomotive built for the Prussian state railways.
The Württemberg AD was a German steam locomotive built for the Royal Württemberg State Railways. It was an express train engine with a 4-4-0 wheel arrangement and was built from 1899 by the Maschinenfabrik Esslingen. Up to that point the railway only had increasingly elderly locomotives with a 2-4-0 configuration.
The Rekolokomotives of DR Class 52.80 first appeared in 1960 in service with the Deutsche Reichsbahn in East Germany as extensive rebuilds of the wartime locomotives or Kriegslokomotiven of the DRB Class 52 built by Nazi Germany. This modernisation, described as 'reconstruction', extended to almost all of the components and systems on the engine.
The steam locomotives of DR Class 22 were reconstructed passenger train locomotives in service with the Deutsche Reichsbahn in East Germany after the Second World War.
The Saxon Class XX were German eight-coupled express train, tender locomotives built for the Royal Saxon State Railways just after the First World War. The locomotives, which became known as the 'Pride of Saxony' (Sachsenstolz) were the first and only German express locomotives with a 2-8-2 wheel arrangement and, at the time of their appearance, were the largest express engines in the whole of Europe. In 1925, the Deutsche Reichsbahn grouped these locomotive into their DRG Class 19.0.
A Bahnbetriebswerk is a German railway depot where the maintenance of locomotives and other rolling stock is carried out. It is roughly equivalent to a locomotive shed, running shed or motive power depot. These were of great importance during the steam locomotive era to ensure the smooth running of locomotive-hauled services. Bahnbetriebswerke had a large number of facilities in order to be able to carry out their various maintenance tasks. As a result, they needed a lot of staff and were often the largest employers in the area.
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 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.
