Wales Governments agreed that ARTC would lease the NSW interstate and Hunter Valley networks for 60 years. As part of this agreement, ARTC agreed to a $872 million investment programme on the interstate rail network. The funding sources for the investment included an Australian Government equity injection into ARTC of $143 million and a funding contribution of almost $62 million by the New South Wales Government. AusLink Under the AusLink program introduced in July 2004, the Australian Government has introduced the opportunity for rail to gain access to funds on a similar basis to that of roads. AusLink established a defined national network (superseding the former National Highway system) of important road and rail infrastructure links and their intermodal connections. Rail funding has been announced for signalling upgrades to numerous railway lines, gauge conversion of existing broad gauge lines in Victoria to standard gauge, new rail links to intermodal freight precincts, and extensions to existing crossing loops to permit longer trains to operate. Funding is focused on the National Network, including the following rail corridors, connecting at one or both ends to State Capital Cities: Sydney–Melbourne railway Sydney–Brisbane railway Sydney to Adelaide, via Sydney–Melbourne railway to Cootamundra and then the Cootamundra–Parkes line, Parkes–Crystal Brook line and the Adelaide–Darwin railway Melbourne-Adelaide railway Adelaide to Perth – Sydney–Perth railway Adelaide–Darwin railway Brisbane to Townsville – the North Coast railway line in Queensland Townsville to Mount Isa Hobart to Burnie, including link to Bell Bay, Tasmania Melbourne to Mildura via Geelong Sydney to Dubbo Some urban links in Sydney, Melbourne, Brisbane, Perth and Adelaide, connecting the long distance links to each other and to ports and airports Hunter Region rail links from Dubbo to Newcastle via the Dubbo-Merrygoen, Merrygoen–Binnaway, Binnaway–Werris Creek and Werris Creek–Port of Newcastle lines and the Merrygoen–Gulgong, Merrygoen–Sandy Hollow and Sandy Hollow–Muswellbrook lines Infrastructure Australia After the 2007 federal election, the government body Infrastructure Australia was created to oversee all rail, road, airports and other infrastructure at a national level. Rail infrastructure Construction and maintenance of network infrastructure is consolidated into non-profit government bodies and contracted private: in the case of the interstate network and various non-urban railways of New South Wales, Victoria and Western Australia, the Australian Government-owned Australian Rail Track Corporation (ARTC); the New South Wales Regional Network, John Holland Rail; and rail infrastructure throughout the southern half of Western Australia, Arc Infrastructure.
