A total of 48 G class engines were acquired by the WAGR between 1889 and 1899, both new and second-hand. They were the first class of locomotives to be introduced to the WAGR network in quantity. They were part of what became almost an Australian 3 ft 6 in (1,067 mm) standard, as locomotives of similar design served in large numbers as the Silverton Tramway Y class, South Australian Railways Y class and Tasmanian Government Railways C class, and also in Queensland and on the Emu Bay Railway and North Australia Railway.[1][2]

They were designed by Beyer, Peacock & Co who built seven, with James Martin & Co building 29 and Neilson & Co 12.[3][2]

During World War II, 13 were loaned to the Commonwealth Railways for use on the North Australia Railway as their Nfc and Nga classes.[4][5] Others were sold for further use by timber mill operators in Western Australia while some saw further service with the Chillagoe Railway & Mining Co, Cairns. The class remained in service in significant numbers until the 1960s.[3][6]
