History

edit

A total of 72 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 on the Chillagoe Railway & Mining Co in Queensland, the Emu Bay Railway in Tasmania and the North Australia Railway in the Northern Territory.[1][2]

They were originally designed by Beyer, Peacock & Co who built nine, with James Martin & Co building 29, Neilson & Co 12 and Dubs and Co 22.[3][2]

During World War II, 13 were sold to the Commonwealth Railways for use on the North Australia Railway which became their NGA and NFC classes.[4][5] Three were also sold to the Chillagoe Railway & Mining Co in 1907, while others were sold for further use by timber mill operators in Western Australia, such as Millars, Bunnings Bros, Kauri Timber Co., Goldfields Firewood Supply and the State Saw Mills. The class remained in service in significant numbers until the 1960s.[3][6] Millars No. 71 "Menzies" (ex-WAGR G 111) was the last G Class withdrawn in 1972, having the mantle of the last steam locomotive in revenue service in Western Australia.
