The South Australian Railways 400 class was a class of 4-8-2+2-8-4 articulated steam locomotives built in France in 1952 and 1953 under licence to Beyer, Peacock & Co. Ltd, Manchester, UK. The locomotives mainly hauled ore on the 3 ft 6 in (1,067 mm) narrow gauge line from the SA/NSW border to smelters at Port Pirie until 1963, when they were replaced by diesel locomotives. They also operated on the lines to Terowie and Quorn. Some locomotives were returned to service in 1969 while narrow gauge diesel locomotives were converted to 4 ft 8+1⁄2 in (1,435 mm) standard gauge. Subsequently some were stored at Peterborough before being scrapped.[1]
