This Report is the last of a series on railway mainline upgrading options and covers the evaluation of options for upgrading the standard gauge link between Kalgoorlie and Perth.

The evaluation of upgrading options differs in this case from those previously reported, in that no capacity constraints are envisaged, but severe and continuing track deterioration has occurred between Koolyanobbing and Kwinana as a result of heavy axle loads in the iron ore and wheat trades. Thus the upgrading requirements in this case are concerned with the use of heavy rail and high standard track rather than the capacity to run more trains.
