Prussian G 8.2
The G 8.2 class consisted of two different types of locomotive: On the one hand, the Prussian / Oldenburg G 8.2 , which was also ordered by the Deutsche Reichsbahn, and on the other hand, the G 8.2 of the Lübeck-Büchener Railway .

The Prussian G 8.2 is a version of the Prussian G 8.3 with two cylinders . It had been found that the maintenance-intensive, internal third engine of the G 8.3 was not absolutely necessary and that simply shortening the G12 did not result in an optimal locomotive design and therefore did not continue to build the G 8.3. Like this, the G 8.2 was developed from the G 12 and represented a shortened version of it. The locomotives were used in heavy freight train service on main lines. Later, the maximum speed was partially increased to 75 km / h so that these locomotives could also be used in passenger train service. A total of 846 examples of this locomotive were built between 1919 and 1928 for the Prussian State Railways and the Deutsche Reichsbahn . Five vehicles, which were delivered to the Reichsbahndirektion Oldenburg in 1921 , received a Lentz valve control , as is usual with Oldenburg machines . The locomotives delivered in 1922 were given numbers from the Cassel division, and in 1923 some were delivered as the 31 series before they were delivered with their final numbers from the end of 1923. The Deutsche Reichsbahn gave the series the road numbers 56 2001–2485 and 2551–2916. In 1930, the AEG company converted four vehicles to use coal-dust firing.
Other largely identical locomotives were delivered to the Turkish and Romanian railways . The Romanian CFR initially received 104 units from German locomotive factories in 1921 and 1922, and the CFR took over another 40 units in 1926 from stocks of the Reichsbahn. The 62 Turkish copies came from Nydqvist och Holm and Tubize . They had somewhat larger boiler lengths and wheelbases, but were otherwise largely identical. The TCDD classified them as TCDD 45 001-062 . The last specimens did not go out of service until 1990, and several were preserved as monument locomotives.
After the Second World War , 650 units of the series were still available in Germany. At the Deutsche Bundesbahn , this series was withdrawn very quickly; the last one was 56 2637 in 1963 and withdrawn in 1965. The main reason for this was that the top speed is now too low for main lines and the axle load is often too high for secondary lines. Locomotives of the series were still used as heating locomotives .
The Deutsche Reichsbahn used these locomotives until the early 1970s. The 1970 renaming plan contained 17 locomotives, some of which had their EDP numbers written down. Due to the thousand digit 2 and the grate firing, only the self-checking number had to be added. The stronghold was the Vacha depot in Thuringia, which, with the 56 2001 and 56 2916, used both the first and the last locomotive built. In Germany, none of the class 56 20-29 locomotives have survived. 56 2795 is in the Warsaw Railway Museum as Tr6-39 .
After the Second World War, 52 machines remained in Poland , which were run by the PKP as the Tr6 series. On December 21, 1972, the last of them, the Tr6-3, was retired.

The G 8.2 of the Lübeck-Büchener Eisenbahn was based on the Prussian G 8.2, but was an independent construction with numerous changes. So it was much longer and therefore didn't seem so squat. They were primarily intended for heavy goods traffic between Hamburg and Lübeck. Since these locomotives were also to be used in passenger train traffic, the running gear and brakes were designed so that the maximum speed could be increased to 75 km / h. A total of eight locomotives were supplied by Linke-Hofmann between 1923 and 1930 . They were never part of the Prussian State Railways, only came to the Deutsche Reichsbahn in 1938, were given the series designation 56 30 and the numbers 56 3001-3008.
The Deutsche Bundesbahn took over the locomotives 56 3001 and 56 3003-3008 and decommissioned them by 1951. 56 3002 remained with the Deutsche Reichsbahn and was retired in 1956.
The locomotive 56 3007 has been preserved and is in the Darmstadt-Kranichstein Railway Museum . After being taken out of service by the DB from 1950 to 1975, it was used as a locomotive at the Carl Alexander mine in Baesweiler .
The locomotives were with a Tender respondents coupled types of pr 3 T16,5, pr 3 T20 or pr 2'2 'T21,5.
