The GM Class units were the first mainline diesel locomotives to enter service with Commonwealth Railways. Their introduction led to the dieselisation of the Trans-Australian Railway between Port Augusta and Kalgoorlie. When similar but more powerful units were introduced, the original GM units became known as the GM1 Class while the newer diesels were referred to as the GM12 Class. GM3 is stored and GM10 is the only member of the GM1 Class remaining in service.
