Track and formation design for the Alice Springs - Darwin railway project

The economics of the Alice Springs – Darwin railway project dictated the need to reduce the construction cost of the project. This, and the large quantities involved, stimulated comprehensive re-examination of the issues influencing track performance and hence design. In particular, the interactions between the railway track and the formation earthworks were extensively studied. This enabled the quantification of the track modulus. Combined with trial embankments it also enabled the derivation of construction methods to achieve the design modulus, and the specification of these methods. A number of conclusions were drawn that provide a better understanding of the interactive behaviour of rail, sleepers, ballast, embankment and subgrade, allowing cost savings whilst maintaining performance.
