Victorian Railways 'S' Class

Clyde Engineering acquired the services of former SAR Chief Mechanical Engineer Fred Shea, to design and oversee the production of a GM-EMD F7 model suitable for use on the Commonwealth Railways system, importantly on the Trans Australia Railway. The equipment was re-arranged to suit Australia's tighter loading gauges, resulting in a lower, longer version of the US EMD unit. The longer carbody facilitated a 3rd, unpowered axle in the bogie, the burden of US axle load being well beyond the tolerance of existing infrastructure.

So impressed was the Commonwealth Railways administration with the locomotive's on-time delivery over 1951/1952, that the
fleet was named the GM Class. Design revisions led to the developement of a Co-Co version, the GM-12 Class with an updated EMD power unit. The modifications added a substantial 100kN to the locomotive's continuous tractive effort, and the success of the GM-12 resulted in orders from the Railways of NSW and Victoria.

The Victorian 'S' Class is of slightly greater horsepower than the GM-12, and was fitted with a hostler's cab at the rear.
The S Class worked over both the broad and standard gauge networks of Victoria on The Spirit of Progress, The Overland,
and on goods services. The introduction of through-working between states saw the Class regularly run into NSW & South Australia.

Today most of the 18 units have been withdrawn, though 4 were returned to service after a period of storage. Private operator West Coast Railway purchased 4 units for use on passenger services, and the last S Class locomotive to enter service for VR, S317 is maintained by Great Northern Railway.
