Prussian G 9
The Prussian G 9 represents the final class of saturated steam locomotives (without superheating) designed for the Prussian state railways. Between 1908 and 1911, a total of 200 units were produced, initially by Schichau and subsequently by several other locomotive manufacturers. Due to reliability concerns with the G 8 and its use of superheated steam, this technology was approached with caution. The locomotive's frame was derived from the G 7 model, while it featured a newly designed, larger boiler. Despite this, the G 9 did not surpass the G 8 in operational performance. Early on, some of these locomotives were classified as G 7 but were later redesignated as G 9. Their primary role involved hauling ore traffic between the Ruhr region and the North Sea.
Following World War I, 58 units were transferred to Belgium where they were designated as type 79, eight were allocated to Poland under the Polish State Railways (PKP) and classified as Tp5, and one was assigned to the Saarland.Template:Sfnb
A total of 133 locomotives were incorporated into the fleet of the Deutsche Reichsbahn, receiving numbers from 55 2301 to 55 2433. During the 1920s, thirty-six of these were retrofitted with superheaters, enhancing both their power output and maximum speed. Those units that remained after World War II were gradually phased out—retirement occurred by 1949 in western zones and continued in East Germany until the last unit, number 55 2361, was withdrawn in 1961—or sold off to private railway companies.
Post-1945, two locomotives entered service with the ČSD, classified as series 427.05. These originally belonged to Poland's PKP Tp5 series but were returned to PKP in 1947.
Each locomotive was paired with a Prussian three-axle tender, type pr 3 T 12, according to diagram sheet III-5b.
