The majority of Western Australian steam locomotive classes were operated by the Western Australian Government Railways (WAGR). Regularly scheduled steam working ceased on WAGR mainline operations after 1971 – with only special excursion or enthusiasts trains being hauled by steam after that time.[citation needed]

Other significant operators include the Commonwealth Railways, the Midland Railway Company of Western Australia and State Saw Mills. Many private organisations also operated steam locomotives in Western Australia.
