The 700 class are a class of diesel locomotives built by AE Goodwin, Auburn for the South Australian Railways in 1971/72. They are identical to the New South Wales 442 class locomotive.
History
The first three were delivered with broad gauge bogies, the last three with standard gauge bogies. In March 1978 all were included in the transfer of the South Australian Railways to Australian National. Over the years the locomotives frequently switched gauges before all were put on the broad gauge in 1987. Following the Adelaide-Melbourne railway line being converted to standard gauge in 1995, all of the 700 class were transferred to the new gauge.[1] The 700 class operated on all main lines in South Australia as well as interstate to Broken Hill and Melbourne.
In 1986, a new computer system required the class leaders of the former South Australian Railways to be renumbered as the last member of the class, with 700 becoming 706.[2] In June 1994 702 was damaged by fire. A New South Wales 442 class locomotive was purchased in December 1994 with the intention of combining the two locomotives as one but the plan did not proceed and both were scrapped.[3][4]
The remaining five were included in the sale of Australian National to Australian Southern Railroad in November 1997. As of January 2015 locomotives 701, 703 and 705 remain in service on standard gauge, 704 has been placed into storage with the end of broad gauge services in South Australia while 706 has been in long term storage and is rumoured to be scrapped.[5][6][7]
