The S class was an express passenger steam locomotive that ran on Victorian Railways, Australia, from 1928 to 1954. Built when the VR was at its zenith and assigned to haul the broad gauge-leg of its Melbourneto Sydney interstate express passenger services, the S class remained the VR's most prestigious locomotive class until the advent of diesel electric locomotives in the early 1950s.
They were the first Pacific-type locomotives on the VR, as well as its first 3-cylinder locomotive type. Renowned for their power and speed, in the ten years that followed their introduction the running time of the premier Sydney express service they operated was progressively reduced by one and a half hours. These service improvements culminated in 1937 with the replacement of the Sydney Limited with the Art Decostreamliner Spirit of Progress, and the S class locomotives were fitted with streamlined casings to match the new train set. They were also equipped with long-range tenders to enable the entire 190 1⁄2-mile (306.6 km) journey to be run non-stop at a speed that remained for the next 20 years Australia's fastest train service.
Although only four S class locomotives were built, they were highly utilised. They ran up annual mileages double that of other classes of locomotives on the VR and by 1954 had run a combined total of approximately 5,700,000 miles (9,200,000 km). However their size and heavy axle load made them unsuitable for regular service on any other lines than the North Eastern line, and so within six months of the introduction of the new B class diesel locomotives on the Spirit of Progress roster in April 1954 the S class had all been withdrawn and scrapped. Their scrapping was a catalyst for the rail preservation movement in Victoria to lobby for the preservation of remaining examples of other VR steam locomotives, resulting in the establishment in 1962 of the Australian Railway Historical Society's North Williamstown railway museum.
We identify rebuilt and renumbered locomotives from this class as well as other classes with similar mechanical configurations and present those classes below.
