The 500 class were part of larger order for 30 steam locomotives placed with Armstrong Whitworth, England, in 1924, as part of the rehabilitation of the state's rail system being overseen by Railways Commissioner William Webb. They replaced the Rx and S class locomotives, many dating back to 1894, that were still performing mainline duties, meaning that double and even triple heading was common. All ten 500-class locomotives arrived in Adelaide in 1926, and entered service on the Adelaide to Wolseley line as far as Tailem Bend. All were named after notable South Australians.

In May 1928, 506 was experimentally fitted with a booster, included in a newly created four wheel trailing truck. This American-inspired modification proved highly successful, increasing the locomotive's tractive effort from 51,000 pounds-force (230 kN) to 59,000 pounds-force (260 kN). This modification was subsequently fitted to the nine remaining locomotives, resulting in the class becoming the 4-8-4 class 500B.

Throughout the mid-1930s all but two of the locomotives in the class were semi-streamlined and had valances fitted. The first two 500-class locomotives were withdrawn from service in 1955 and the last was withdrawn in 1962.

504 is preserved as a static exhibit at the National Railway Museum, Port Adelaide.
