Maldon-Port Kembla railway: stability of major earthworks embankment at 96 km

The major part of the effort and money put into a railway system goes into a minor part of the total track length. Major bridges require significant expenditure during construction, but hopefully these areas are almost maintenance-free once the line is operating. This paper deals with a section of track that involved a major construction effort when it was built in the 1930's and today, 55 years later, is still involving far more than average maintenance for a length of railway line. The line from Unanderra near Port Kembla to Moss Vale was started in 1927 and finished in 1932, with much of the work being done by large gangs during the depression times. The first section of line, from Unanderra to Summit Tank on the edge of the plateau, rises for 750 metres. The gradient is at 1 in 30 passing across the face of a steep unstable excarpment, covered with rain forest and in an area of high rainfall. Due to its past strategic importance of transporting steel and industrial products from Port Kembla to southern New South Wales and Victoria, the cost of maintaining this line was never queried. In 1983, the Government gave approval for a new railway line to be constructed from Maldon on the southern line to carry heavy coal trains from western and near southern NSW, heading for the Port Kembla coal loader. This line joins the existing track on the escarpment, at Dombarton, and from there to Unanderra the track will be duplicated in this difficult section of country.
