The steam locomotives of the class G 3/4 H of the Bavarian State Railways were built between 1919 and 1923. What was striking about it compared to the G 3/4 N were the superheated steam engine , the feed water preheater , the larger and higher boiler and the reintroduced Adams axis instead of the smoother Krauss-Helmholtz frame . Thanks to the new boiler and the larger grate surface, it was more powerful and more economical than its predecessors. All 225 copies built were put into operation by the Bavarian Group Administration of the Deutsche Reichsbahn with Bavarian numbers.
In the last phase of steam locomotive development in Bavaria, the locomotive fleet was modernized in terms of performance and economy. Even after the establishment of the Unification Committee (narrow committee for locomotives for the unification of locomotives) in 1921, particularly well-proven locomotive types were still built, including the G 3/4 H series For a long time, freight train service had no more suitable locomotives available.
The first locomotives had the dome and the sand container under a common angular panel on the top of the boiler. From road no. 7166 (DR 54 1656) the dome and sand container were separated and arranged under round cladding. At the same time, the boiler mass was also increased, which helped to reduce the risk of skidding. According to the final second numbering plan of the Reichsbahn , the vehicles were later given the operating numbers 54 1501–1725. After electrification, some of the locomotives were used in northern German depots. The majority of the locomotives survived the Second World War and, with a few exceptions, came to the Deutsche Bundesbahn. The last locomotive (with the road number 54 1632) was not taken out of service until 1966 in Nuremberg.
The 54 1534, 1548, 1550, 1559, 1607, 1625, 1637, 1663 and 1691 remained in Austria after the Second World War. The ÖBB added them to their vehicle fleet as ÖBB series 654 , retaining the serial number . By 1957, all machines in the 654 series had been taken out of service. The 654.1663 came to the main workshop in Simmering as a service locomotive in 1956 , where it was given the number 913.502.
The vehicles were traveling with a Tender equipped to type bay 3 T 18.2.
Preserved locomotives and parts
During civil engineering work in the course of the construction of a new platform between tracks 7 and 8 in Treuchtlingen station , locomotive parts were found on July 13, 2004, which turned out to be remnants of 54 1695.
The 54 1695 (bay.G3 / 4H 7195) was built with the serial number 5395 in 1922 in the JA Maffei locomotive and machine factory in Munich and delivered to the Bavarian group administration of the Deutsche Reichsbahn with the number Bavaria 7195.
The locomotive from the inventory of the Munich railway depot was destroyed during the bombing on February 23, 1945 and buried in a bomb crater during the clean-up work.
The remains of the locomotive - part of the tender, the surface preheater with compressed air boiler and the 1st and 2nd axles - are exhibited in the Bavarian Railway Museum on loan from the Nuremberg Transport Museum and the DB Museum.
