The South Australian Railways 500 class was a class of 4-8-2 steam locomotives operated by the South Australian Railways. The locomotives were rebuilt in 1928, when booster engines were installed, becoming the 500B class with a wheel arrangement of 4-8-4 and a tractive effort of 59,000 pounds-force (260 kN). The 500B class were the second-most-powerful non-articulated steam locomotives to operate in Australia, behind the NSWGR D57 4-8-2.
