# List of Western Australian locomotive classes

This is a list of Western Australian locomotive classes, being classes of locomotive that have worked on railways in Western Australia.
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.
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.
