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[edit]

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 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.[2][3]

The remaining five were included in the sale of Australian National to Australian Southern Railroad in November 1997. As of December 2013 four remain in service hauling South Australian freight services.[4][5][6]
