The Prussian Class T 3 steam locomotives procured for the Prussian state railways were 0-6-0 tank locomotives. Together with the Prussian T 2 they were the first locomotives that were built to railway norms. The first units were delivered by Henschel in 1882.
The T 3s had a wet steam engine with two cylinders that drove the centre coupled axle. The slide valves were worked by an outside Allan valve gear. The water supply was stored in a well tank between the frame under the boiler; the coal bunkers were on the left and right hand side of the firebox. In front of each one was a filler pipe for the water tank.
The springs on both front axles were linked with equalising beams located above the running plate.
The early T 3s did not have a steam dome, but were equipped with a regulator housing on top, from which the admission pipes led directly to the cylinders outside the boiler. The axle load of this locomotive was about 10 t (see first photo).
Later batches (from 1887) had a steam dome, and the admission pipes were located in the smokebox. Due to the addition of the steam dome, the location of the sand box and sanders were changed. In addition the quantities of water and coal that could be carried were increased. The back wall of the cab was now straight and the lower section no longer sloped. The length over buffers increased from 8,300 mm to 8,591 mm, the axle load rose to 11 t (see second photo).
From 1903 the supplies were increased again and the T 3 could now carry 5 m3 of water and 1.9 t of coal. The axle load of this "strengthened standard class" or "Standard class (6t)" (Normalbauart (6t)) was 12 t.
A total of more than 1,300 T 3s were built for the Prussian state railways. But many other railways in Germany and abroad, from industrial railways to national railways, also bought locomotives based on the T 3 pattern, including the:
In 1925 the Deutsche Reichsbahn (DRG) took over 511 Prussian T 3s as their Class 89.70–75. The 473 locomotives of the older version were given numbers 89 7001–7456, 7473–7476 and 7499–7511. The 38 locomotives of the stronger design were given numbers 89 7457–7472 and 89 7477–7498.
In incorporating locomotives later on from private railways that they had taken over, the DRG were not very logical. As a result, Class 89.75 ended up with a mixture of various locomotives types, in some cases with numbers that followed directly on from one another.
By the start of 1931 the DRG fleet of T 3s had been reduced to 254 units however, after the Second World War numerous T 3s entered the Deutsche Bundesbahn and Deutsche Reichsbahn in East Germany, where the last examples were retired in the mid-1960s.
After 1945 the Deutsche Reichsbahn in the GDR inherited large numbers of T 3s from industrial and private railways as numbers 89 953, 5901–5903, 6001–6016, 6018, 6101–6132, 6134–6159, 6161, 6163, 6164, 6204–6211, 6215, 6216, 6218, 6220, 6221, 6228–6232, 6235, 6306, 7566–7568, 7571–7573 und 7578. These included several 'genuine' Prussian T 3s.
The former 89 7535 of the Gardelegen-Neuhaldensleben-Weferlingen railway was incorporated in 1949 into the DR fleet and was given number 89 6220. This locomotive was not retired until 1967, the last T 3 in service with the DRG. The last T 3 engine on active duty, however, was the industrial engine at the Warburg Sugar Factory which retired in 1979 .
Four more examples, which came from the Oderbruchbahn , were converted by the DR in 1960 and equipped with tenders. These engines were numbered 89 6222–6225 One example, 89 6222, was initially given a four-wheeled tender, the others a Class 3 T 12 tender. One of these later replaced the four-wheeled tender as well. The locos finished their service with the Kreisbahn Beeskow–Fürstenwalde which took them on in 1950 and withdrew them in 1968.
Around 70 T 3s ended up in the DB, the last one, 89 7538, being retired in 1963. However T 3s appeared briefly in the DB fleet later on. These were the industrial locomotives, nos. 2 and 3 from the Ausbesserungswerk at Schwerte, which were officially added to the DB fleet in 1968 as 089 002 and 089 003. The former locomotive 89 7531 hid behind number 089 003. It was finally retired on 21 June 1968 as the last T 3 in DB service.
Several T 3s have been preserved today by museums, some being still operational. To these belong one of the locomotives with a tender, number 89 6009 (89 7403 before its conversion), which is a DB AG museum locomotive stabled at the Dresden Transport Museum.
The Prussian Class S 3s were saturated steam locomotives developed by Hanomag for the Prussian state railways and were built from 1893.
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.
The Prussian G 8.1 was a heavier, stronger development of the G 8 and was initially referred to as a 'strengthened standard class'.
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.
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 Prussian G 12 is a 1'E 2-10-0 goods train locomotive built for the Prussian state railways.
The Württemberg Class K steam locomotives of the Royal Württemberg State Railways were the only twelve-coupled locomotives built for a German railway company.
The Alsace-Lorraine Class G 8.1 was a superheated, goods train, steam locomotive with four driving axles, and was based on the Prussian G 8.1. There were no design differences between the two. The Imperial Railways in Alsace-Lorraine received a total of 137 G 8.1 engines between 1913 and 1919, of which eleven were built by Henschel and the rest by the Grafenstaden. They were numbered 5151 to 5278.
The Prussian G 10 was a German goods train, steam locomotive, whose design was based on a combination of the running and valve gear from the Prussian T 16 and the boiler from the Prussian P 8. In developing the G 10, however, the T 16 running gear with side play on the first and fifth axles was modified. The T 16 was also subsequently built with this modified configuration and called the Prussian T 16.1. The G 10 was intended for heavy goods train duties on main lines, but as a result of its low axle load it could be employed more flexibly than its equally powerful cousin, the Prussian G 8.1. The G 10 was occasionally even used in passenger train service.
The Oldenburg G 7 steam locomotive was a German 0-8-0 locomotive produced for the Grand Duchy of Oldenburg State Railways. It was an eight-coupled engine, intended for heavy goods train duties, and was based on the Prussian G 7. It had a 1,660 mm diameter boiler located 2,820 mm above the top of the rails in the plate frame, and was equipped with a single Walschaerts valve gear as well as a Lentz valve gear. Thirteen were taken over by the Deutsche Reichsbahn, grouped into DRG Class 55.62 and given numbers 55 6201–55 6213.
The Mecklenburg T 4 was a German steam locomotive built for the Grand Duchy of Mecklenburg Friedrich-Franz Railway as a goods train 2-6-0T with a leading axle and three coupled axles. In 1925 it was incorporated in the renumbering plan of the Deutsche Reichsbahn as DRG Class 91.19.
The Saxon Class III b were German steam locomotives built for the Royal Saxon State Railways in the late 19th century as tender locomotives for express train duties. In 1925, the Deutsche Reichsbahn incorporated the engines into DRG Class 34.77-78.
The Prussian Class P 6s were passenger locomotives operated by the Prussian state railways with a leading axle and three coupled axles.
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 Class G 8 locomotives were eight-coupled, superheated, freight locomotives operated by the Prussian state railways. There were two variants: the G 8 built from 1902 with a 14 tonne axle load and the "reinforced G 8" built from 1913 with a 17-tonne axle load. The latter was the most numerous German state railway (Länderbahn) locomotive, over 5,000 examples being built.
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 Prussian G 7.2 was a class of 0-8-0 tender compound locomotives of the Prussian state railways. In the 1925 renumbering plan of Deutsche Reichsbahn, the former Prussian locomotives produced from 1895 to 1911 were given the class designation 55.7–13; while the locomotives of former Mecklenburgische Friedrich-Franz-Eisenbahn (MFFE) locomotives were classified as 55.57.
The Prussian G 4.2 was a class of compound 0-6-0 goods locomotive of the Prussian State Railways. It was a compound version of the G 3 and G 4.1 types by Henschel.
