The South Australian Railways 400 class was a class of 4-8-2+2-8-4 steam locomotives built in the early 1950s. The 400 class locomotives mainly hauled mineral trains on the South Australian Railways' narrow gauge Broken Hill line from 1953 to 1963, when they were replaced by diesel locomotives. They operated as far as far south as Port Pirie and Terowie and as far north as Quorn. The 400 class was temporarily returned to service in 1969 while the diesel locomotives were converted to 4 ft 8 ¹⁄₂ in (1,435 mm) standard gauge. Two have been preserved, 402 at the Zig Zag Railway, Lithgow and 409 at the National Railway Museum, Port Adelaide.
