The German Class 23 (Baureihe 23 or BR 23) engines of the Deutsche Reichsbahn (DRG) were standard ( Einheitslokomotiven ) steam engines that were conceived as a replacement for the Prussian P 8 by the Schichau Works. They were given the same boiler as the Class 50s which were developed in parallel and, like them, the newly developed 2'2' T 26 tender with its front wall that protected train crews during reverse running.

In 1941 the two prototypes were built and delivered. The procurement of 800 locomotives had been planned, however the constraints of the Second World War meant that they never entered full production.

After the war the two locomotives, with operating numbers 23 001 and 23 002, went to the DR in East Germany and were variously stabled in Berlin, Brandenburg an der Havel, Jüterbog and Halle. In 1961, number 23 001 was given a Reko boiler with combustion chamber, developed for the Class 50. In 1970 the locomotive was given EDP number 35 2001–2. Number 23 002 was to be reconstructed, but was retired however in 1967 due to damage to the frame and scrapped. Number 23 001 was scrapped in 1975 in Cottbus, as it could no longer serve any useful purpose.

After the war, the design of these Class 23 locomotives formed the basis for the new DB Class 23 and DR Class 23.10 locomotives which received the same class designation.

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 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.

<span class="mw-page-title-main">DRG Class 56.2–8</span>

Between 1934 and 1941 the Deutsche Reichsbahn (DRG) converted a total of 691 former Prussian-built Class 55.25–56 steam locomotives; the result was the DRG Class 56.2–8. The carrying axle enabled higher speeds and the engine could even be used as a passenger train locomotive. In addition the average axle load was lower, so that these locomotives could also be used on branch lines. The conversion entailed moving the boiler forward and raising it somewhat. The vehicles were given operating numbers between 56 201 and 56 891, although the numbering was not continuous.

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 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.

<span class="mw-page-title-main">Henschel-Wegmann Train</span>

The Henschel-Wegmann Train was an advanced passenger express train operated by the Deutsche Reichsbahn in Germany, which ran non-stop express services between Berlin and Dresden from June 1936 to August 1939. Both the DRG Class 61 steam locomotive at its head as well as the coaches were streamlined.

<span class="mw-page-title-main">LBE Nos. 1 to 3</span>

Locomotive numbers 1 to 3 on the Lübeck-Büchen railway in Germany were streamlined tank locomotives. The locomotives had a 2-4-2T wheel arrangement, a two-cylinder, superheated engine and were capable of push-pull operations. In order to ensure a symmetrical running gear, both carrying axles were built as Bissel bogies, which were fitted with return devices for improved running.

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 S 9 was an express steam locomotive with the Prussian state railways, first built in 1908. It had a 4-4-2 (Atlantic) wheel arrangement and a four-cylinder compound engine. It was developed by the firm of Hanomag in Hanover who delivered a total of 99 engines of this class.
