The steam locomotives of type G 5.5 of the Prussian State Railways were freight train locomotives in composite design . These locomotives, however, had an Adam's axle instead of a Krauss-Helmholtz steering rack compared to the largely identical locomotives of the G 5.4 class . At the Grand Ducal Mecklenburg Friedrich-Franz-Eisenbahn , locomotives of this type were classified in class XX , from 1910 G 5.4 . After the establishment of the Deutsche Reichsbahn , they were assigned to the 54.10 and 54.12 series. The locomotives were still in use until after the Second World War.
history
Prussian State Railways
At the beginning of the 20th century there was no consensus on the cheap design of leading axles. A wide variety of designs (Adams axle, Bissel frame , Krauss-Helmholtz steering frame, bogie) were discussed. Above all, the locomotive procurement department of the Prussian railways Robert Garbe preferred Bissel frames and bogies over Krauss-Helmholtz steering frames. As a result of this debate, following the locomotives of type G 5.4 1909/1910 with steering racks, a smaller series of locomotives with an improved design of the Adam's axle were created. The pattern sheet for the construction was given the designation III3n. The locomotives were used in the administrative districts of Halle and Hanover.
The exact number of locomotives of the genus fluctuates in the literature between 23 and 28. In particular, the allocation of the locomotives hall 4340 to 4344 is disputed. After the First World War , seven locomotives were given as reparations to Poland (Ti-4) and five to Belgium. The Deutsche Reichsbahn redrawn 16 machines in 1925. They were given the numbers 54 1067–1069 (Hall 4340, 4342, 4344) and 54 1080–1092. In 1941 four of the locomotives delivered to Poland were given the Reichsbahn numbers 54 1121, 1141, 1157, 1185.
Mecklenburg Friedrich-Franz Railway
At the Friedrich-Franz-Eisenbahn in Mecklenburg, traffic on the feeder route to the Warnemünde ferry port increased sharply from 1900 onwards . For freight traffic on the route, nine locomotives based on the Prussian type G 5.4 were procured between 1906 and 1913. For the front running axle, however, an Adam's axle was chosen instead of the Krauss-Helmholtz steering frame. It was hoped that this would reduce the wear and tear on the wheel tires and put less strain on the superstructure . The locomotives could move a 790 t train at 50 km / h on the plain and 375 t on a 10 ‰ gradient at 25 km / h.
The locomotives with the track numbers 451 to 459 were classified in class XXI. From 1910 they were given the generic designation G 5.4. After the First World War, five locomotives had to be handed over to Belgium as reparations. There they were given the designation B 7400 to 7404 and were retired by 1940. The Deutsche Reichsbahn redesigned three locomotives as 54 1201 to 1203. The retirement took place until 1930.
Imperial Railways in Alsace-Lorraine
In 1912 the Elsässische Maschinenbau-Gesellschaft Grafenstaden built three locomotives for the Reichseisenbahnen in Alsace-Lorraine based on the drawings of the Prussian G 5.4, but with an improved Adam's axle (Bissel frame type Krauss). From 1912 the locomotives were given the number 4271 to 4273. In 1938 the 4273 was given the designation 130-C-273 at the SNCF .
Constructive features
The design of the locomotive was based on the previous models G 5.3 and G 5.4. The inner frame consisted of 25 mm thick sheet metal plates. The long shell was made from three riveted sections. The steam dome with the flat slide regulator was on the middle shot. The Ramsbottom safety valve was in front of the cab. The boiler was fed by two Strube steam jet pumps.
The external two-cylinder wet steam engine was slightly inclined. The steam engine worked on the central coupling axle. The high pressure cylinder was on the right and the low pressure cylinder on the left. The Heusinger control was external. A start-up device from Borries was used.
The drive was supported at four points. The individual leaf spring packages were arranged under the axle bearings. The spring assemblies of the wheelset and the first coupling axle as well as those of the two rear axles were each connected by balancing levers. The wheelset was designed as an Adam axle with a lateral displacement of 45 mm each. In the Prussian locomotives, the wheel set was reset by means of coil springs.
The locomotives had a handbrake and later a Westinghouse air brake . The sandpit was on the rearmost part of the boiler. The sand spreader sanded the center axle set from the front.
