The interstate freight rail network in SA comprises links between Adelaide and Perth, Melbourne, Sydney and Darwin (via Tarcoola). The DEC of freight rail in SA is projected to increase from $13 million in 2011 to $15 million in 2031, an increase of around 20 per cent. There is no evidence of capacity constraint.
Interstate rail freight between SA and WA is forecast to double between 2013 and 2030. The key driver of demand in this rail corridor is the rail market share for freight between Melbourne, Sydney, Adelaide and Perth, with Melbourne and Sydney volumes dominating. The Tarcoola to Darwin rail line has strong market share for freight on the Adelaide to Darwin corridor, and supports the development of mines and other resource developments along the corridor.
