The Australian Standard Garratt (ASG) was a Garratt steam locomotive designed in Australia during World War II, and used on narrow gauge railway systems in Queensland, South Australia, Western Australia and Tasmania. History With the outbreak of World War II, in 1939 the Federal Government formed the Commonwealth Land Transport Board (CLTB) to take responsibility for the country's land transport networks. It had the power to override the decisions of the State railways. In 1942, the CLTB appointed the Commissioner of Railways in Western Australia, Joseph Ellis, to investigate the capacity of Australia's narrow gauge network and recommend what locomotives should be purchased. Ellis recommended that three variations of Garratt locomotive be purchased; heavy, medium and light. The CLTB elected to build only the light type to allow it to operate on any narrow gauge line in Australia. After an attempt to obtain drawings and licenses from Beyer, Peacock and Company failed, in July 1942 the CLTB recommended to the War Cabinet that 30 locomotives be built locally. In August 1942, the War Cabinet approved the order, this was increased to 65 locomotives in November 1942. The Western Australian Government Railways' Chief Mechanical Engineer Frederick Mills was seconded to lead a team of engineers in Melbourne to design the new locomotive. The Queensland Railways were vocal opponents, stating its preference for a modified version of its C17 class. The result was the Australian Standard Garratt, with the first locomotive being built in a record breaking four months to enter service in September 1943. Only 57 ASGs were completed, with assembly of the remaining eight cancelled at the end of the war. The locomotives were built by the WAGR's Midland Railway Workshops (10), the Victorian Railways' Newport Workshops (12), the South Australian Railways' Islington Railway Workshops (13), and Clyde Engineering, Sydney (22). In service Because of differences between the states, especially in regard to loading gauges, the sharpness of curves, and axle load, especially in Queensland, the design had to be a compromise, which went against the idea of having a standardised design. To enable the long-wheelbase engine units to negotiate sharp curves, the leading driving wheels were designed to be flangeless, but this proved to be a major flaw as it led to a tendency for the locomotives to derail on curves and points. Another key problem, which made the ASGs unpopular with locomotive crews, was the fact that the
