One thing that I have discovered that is not being made with big fanfare is the fact that the Newell Hwy has been receiving funds to upgrade it in direct competition to Inland Rail. They are currently building a bypass around Parkes and Coonabarabran. They finished the Moree bypass a couple of years ago, and are looking at Narrabri and Wyalong/West Wyalong, then Dubbo.The original IR business case has a graph in it showing the growth on the corridor, and the mode shares. Essentially the inland is modelled to take all the new growth but existing traffic levels will remain. So bypasses etc are probably still needed.
Plus theyre good vote winners in the country...
