The German locomotives of DRG Class 43 were standard (see Einheitsdampflokomotive ) goods train engines with the Deutsche Reichsbahn.

History

This was the second class that was built on the Einheitslok principle. According to the first classification scheme of the DR's Standardisation Bureau, 2-10-0 goods train locomotives were to be procured with a 20-ton axle load. To achieve this a two-cylinder class (the Class 43) and a three-cylinder class (the Class 44) were envisaged, because it was not yet known which configuration would be more economical. Ten examples of each class were procured in parallel. The Class 43 was supplied by Henschel and by Schwartzkopff.

In trials it was discovered that the Class 43 was more economical to operate at powers under 1500 PSi. As a result, a further 25 examples of the 43 were ordered up to 1928. However, due to the increase in goods train speeds in the 1930s, the Class 44 was given priority thereafter because, in addition to its economy when running at higher speeds and the better running qualities of its three-cylinder driving gear, it was also cleared for running at up to 80 km/h. [1] As a result, no more Class 43s were ordered.

In the literature statements are often found that the locomotive was not sufficiently powerful overall. In response to that, number 43 013 was loaded for testing purposes with a train of 5000 tons - that is more than twice that given in the haulage tables - and headed it without complaint. In doing so, 43 013 is a record holder. Never before or since has any German locomotive hauled such a load. [2]

The Class 43s, which had operating numbers 43 001 - 43 035, all remained with the DR in East Germany after the Second World War. In 1960, the remaining engines were once again modernised, the powerful boiler even enabled goods trains greater than the maximum allowable load to be hauled. This led, however, to frame damage, that the Reichsbahn could not repair. So the machines were rapidly retired, the last one being taken out of service in 1968 at Cottbus locomotive depot. Locomotive 43 001 became a museum locomotive and belongs to the Dresden Transport Museum, but is in the Saxon Railway Museum, a former home depot of the Class 43.

The engines of this class were equipped with a 2'2' T 32 tender.

DRG Class 01

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.

Prussian P 10

The Prussian state railways' Class P 10 were 2-8-2 "Mikado" type passenger-hauling steam locomotives built for hauling heavy express trains in the hilly terrain of the Mittelgebirge. They were the last Prussian passenger train steam locomotives to be developed in Prussia before the state railways were merged into the Deutsche Reichsbahn, who eventually designated them as DRG Class 39.

DRG Class 86

The DRG Class 86 was a standard goods train tank locomotive with the Deutsche Reichsbahn-Gesellschaft. It was intended for duties on branch lines and was delivered by almost all the locomotive building firms working for the Reichsbahn. From 1942 it was built in a simplified version as a 'transitional war locomotive'. The most obvious changes were the omission of the second side windows in the cab and the solid disc carrying wheels.

Bavarian Gt 2×4/4

The Bavarian Class Gt 2×4/4 engine of the Royal Bavarian State Railways, was a heavy goods train tank locomotive of the Mallet type. It was later designated the DRG Class 96 by the DRG, DB and DR.

DRB Class 42

The DRB Class 42 was a type of steam locomotive produced for the Deutsche Reichsbahn. It is one of the three main classes of the so-called war locomotives (Kriegslokomotiven), the other two being class 50 and 52.

DRG Class 44

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.

DRB Class 41

The German Class 41 steam locomotives were standard goods train engines (Einheitslokomotiven) operated by the Deutsche Reichsbahn (DRB) and built from 1937 to 1941.

DRG Class 02

The German DRG Class 02 engines were standard (Einheitslokomotiven) express train locomotives with the Deutsche Reichsbahn-Gesellschaft. Number 02 001 was the first Einheitsdampflokomotive in the DRG to be completed.

DRB Class 06

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.

DRG Class 62

The Class 62 engines were standard passenger train tank locomotives of Germany's Deutsche Reichsbahn-Gesellschaft (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.

DRB Class 03.10

The German Class 03.10 engines were standard steam locomotives (Einheitsdampflokomotiven) belonging to the Deutsche Reichsbahn and designed for hauling express trains.

Einheitsdampflokomotive

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.

Prussian T 18

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.

Prussian T 20

The German DRG Class 95 was a ten-coupled tank locomotive with a 2-10-2 wheel arrangement, which was procured by the Deutsche Reichsbahn in 1922 for hauling heavy goods trains on steep main lines. Because the development of this class was begun by the Prussian state railways, it was designated as the Prussian Class T 20.

DR Class 58.30

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.

Prussian S 6

The Prussian S 6 was a class of German steam locomotive with a 4-4-0 wheel arrangement operated by the Prussian state railways for express train services.

Prussian T 14.1

The Prussian Class T 14.1 was a German 2-8-2T, goods train, tank locomotive operated by the Prussian state railways and the Royal Württemberg State Railways. They were later incorporated by the Deutsche Reichsbahn into the DRG renumbering plan for steam locomotives as DRG Class 93.5–12.
