Built-in 1951 for Commonwealth Railways by Clyde Engineering under license from General Motors, the eleven members of the GM1 class were ordered primarily to dieselise operations, following on from overseas examples. The GM1 Class was based on the US EMD F7 model, with a number of alterations to ensure that they fitted the local loading gauge and axle load restrictions. Part of the design for the first eleven locomotives was to have an unpowered center bogie – making the wheel arrangement A1A-A1A. All eleven members of the class were delivered by July 1952, displacing most mainline steam on the Commonwealth Railway network.
Presently, only GM10 survives in active commercial service, having the distinction of being the oldest working commercial diesel locomotive in Australia. GM1 and GM2 are both preserved, while GM3 is stored at the Downer Rail workshop at Lithgow State Mine Railway.

As a follow on to the original eleven locomotives ordered by the CR for their system, a further thirty-six units GM Class were ordered to allow for network expansion, albeit in the now common Co-Co wheel arrangement. To assist with the heavy coal traffic at Leigh Creek, the final eleven members of the class were delivered with dynamic brakes. Rather than creating a new class designation, these locomotives were delivered to follow on from the GM1 Class. To help distinguish between the two classes, Australian National (what CR was known as prior to being integrated into National Rail) distinguished these units as “S Class” (six motor), compared to the GM1 Class, known as the “F Class” (four motor).
In the post-privatisation world, a number of these veteran units survive in commercial operation today. GM’s 22 and 27 are owned and operated in NSW/Victoria by Southern Shorthaul Railroad, having been purchased from CFCLA, while the remaining operating members of the class are employed on grain and infrastructure trains in South Australia with US-based operator One Rail Australia (ORA), formerly known as Genesee & Wyoming Australia (GWA).
