The South Australian Railways S Class is broad gauge, 1,600 mm (5 ft 3 in), 4-4-0 steam locomotives, designed as an express locomotive for the route between Murray Bridge and the border with Victoria. The S class had 6'6" driving wheels, the largest of any Australian locomotive, to give it high speeds on low grades.[1]
The engines were pushed out of main line service in the 1920s by 600 class locomotives and Brill railcars. They continued to serve on secondary service into the 1950s with the last examples being retired in 1961.[1]
No S class locomotives survived to this day. One engine was set aside for preservation, however it was inadvertently scrapped.
