South Australian Railways 400 class

The South Australian Railways 400 class comprised ten 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 1067 mm (3 ft 6 in) narrow-gauge line from the New South Wales/South Australia border to smelters at Port Pirie until 1963, when they were replaced by diesel locomotives. They also operated on the line to the break-of-gauge station at Terowie. 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.
