The vehicles of the class GE of the South African Railways (SAR) were steam locomotives of the Garratt design . They were intended for passenger train service on main lines.
history
The class was a further development of the GA class test locomotive . However, the locomotives were given four coupled wheel sets twice - Garratt was the second ever - and inner wheel sets . At 13.6 t they had a significantly lower axle load than the GA class (17.8 t) and still had a slightly higher tractive power. In 1925 a single GG class locomotive was also built, which had the same boiler, but had larger drive wheels and the axle arrangement (1'C1 ') (1'C1').
The 18 locomotives of the GE class were procured in three series in 1924/25, 1926 and 1930. The last series of two pieces had an enlarged cylinder diameter. The locomotives of the first series initially ran between Johannesburg and Zeerust ; later, the entire class was used on the north coast stretch from Durban .
In the 1970s, the GE were replaced by more modern Garratts of the GEA and GO classes . Locomotive No. 2260, the first of the class, has been preserved.
Sierra Leone Development Corporation
In 1931 the Sierra Leone Development Corporation (SLDC) procured two locomotives that corresponded to the second series of the GE class, but were built for meter gauge . Two more machines followed in 1936 and 1937. Until the introduction of diesel locomotives in 1955, they handled the entire line service of the railway. After they were taken out of service, they were offered for sale; however, since no buyer was found, they were scrapped.
