The steam locomotives of the Prussian type G 5.4 were freight locomotives in composite design . The G 5.4 as well as the G 5.3 were distinguished from the G 5.1 and G 5.2 by a shorter wheelbase and a higher boiler position. The Krauss-Helmholtz steering frame should improve the driving characteristics, especially at higher speeds.
Between 1901 and 1910 a total of around 750 G 5.4 vehicles were built for the Prussian State Railways . The last 25 locomotives were again equipped with an Adam axle and designated as the Prussian G 5.5 .
Due to its top speed of 65 km / h, it was also used in passenger transport.
Other railways also procured this type:
- Port railway Frankfurt / M : 3 pieces from 1908, taken over by the Prussian State Railways in 1910 .
- Royal Prussian Military Railway : A locomotive from 1905 (Borsig, F.Nr. 5856, train number Kgl.Mil.E. 105), taken over by the Prussian State Railways in 1919 .
- Lübeck-Büchener Eisenbahn : Three locomotives from 1906 and 1909, retired by 1936.
- Mecklenburgische Friedrich-Franz-Eisenbahn : Nine locomotives, actually G 5.5, see Mecklenburgische G 5.4 .
- Reichseisenbahnen in Alsace-Lorraine : three locomotives from 1912, G 5.5, see Alsace-Lorraine G 5.5 .
The Reichsbahn took over in 1923 in their renumbering plan still 371 ( or 341 ) locomotives as 54503-517 and 54801 to 1156 ( or: 54801-54 1143, including, however, the G 5.5 ); In 1925, 278 ( or: 274 ) vehicles were redesignated as 54 801-981, 985-1079, 1083 and 1084 ( or: 54 801-982, 54 985-1066 and 54 1070-1079 ). Around 22 units were converted into superheated steam locomotives in the twenties .
At PKP , the machines were carried under the series designation Ti4. In 1926, 195 machines and two more were available for use in the Free City of Danzig . After the end of the Second World War, the PKP still operated 60 G 5.4 units.
During the Second World War , several G 5.4 and G 5.5 from Poland and Lithuania came into the Reichsbahn's inventory as 54 1101–1218 and 54 1220–1223. The last G 5.4 in Germany were retired by 1951.
The vehicles were equipped with a tender type pr 3 T 12 (according to sample sheet III 5 b), pr 3 T 15 (according to sample sheet III 5 c) and pr 4 T 16 (sample sheet III 5 f).
