Prussian G 5.1
Encyclopedia
The Prussian Class G 5.1 steam engines were the first 2-6-0
goods locomotives in Europe. They were developed for the Prussian state railways
from the Class G 4 and a total of no less than 268 units of this class were placed in service in Prussia
between 1892 and 1902. The twin-cylinder G 5.1 had been designed to raise the speed of goods trains on main lines. In addition, more powerful engines were needed for the increasingly heavy train loads. The locomotives, which were equipped with a compressed air brake, were used in charge of fast goods trains (Eilgüterzugdienst) and also passenger trains due to their impressive top speed of 65 km/h. The G 5.1 was fitted with inside Allan valve gear and the carrying wheels were of the Adams axle
design.
In 1923 the Reichsbahn
listed 169 G 5.1's as nos. 54 001 - 168 and 54 182 as part of their renumbering plan for steam locomotives
; in 1925 only 71 examples, with running numbers 54 001 - 54 071 were recorded. The locomotives were all retired by 1930.
During the Second World War, three G 5.1 returend to the Reichsbahn fleet from Poland
and were numbered 54 601 - 603.
The engines were coupled with tenders of Class pr 3 T 12.
2-6-0
Under the Whyte notation for the classification of steam locomotives, 2-6-0 represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, six powered and coupled driving wheels on three axles, and no trailing wheels. This arrangement is commonly called a Mogul...

Adams axle
The Adams axle is a form of radial axle for rail locomotives that enable them to negotiate curves more easily. It was invented by William Bridges Adams and patented in 1865. The invention uses axle boxes that slide on an arc in shaped horn blocks, so allowing the axle to slide out to either side...
