The South Australian Railways 930 class was a class of diesel-electric locomotives built for the South Australian Railways between 1955 and 1967 by AE Goodwin, Auburn, New South Wales, the Australian licensee of the American Locomotive Company (Alco). Based on the Alco DL500B World series model, they were fitted with Alco 12-251B four-stroke V12 turbocharged diesel engines that developed 1600 horsepower (1190 kilowatts) for traction. The first six of the class had a driving cab at one end only; the remaining 31 locomotives had two. The latter series, up-rated, were the basis of the almost identical New South Wales 44 class, of which 100 were built from 1957.^[1]
