ARTC’s undertaking sets out the principles and processes under which ARTC, as an infrastructure provider of rail, will be obliged to provide access to businesses wishing to run trains on ARTC’s interstate rail network.
The interstate rail network covers the mainline standard gauge track linking Kalgoorlie in Western Australia, Adelaide, Wolseley and Crystal Brook in South Australia, Melbourne and Wodonga in Victoria and Broken Hill, Cootamundra, Albury, Macarthur, Moss Vale, Unanderra, Newcastle (to the Queensland border) and Parkes in New South Wales (NSW). Since the 2013 Variation it has also included the South Sydney Freight Line (SSFL). The 2018 Interstate Rail Access Undertaking proposes to include the Queensland Border Loop to Acacia Ridge segment into an expanded Newcastle to Acacia Ridge segment. It also proposes to include the Sydney Metropolitan Freight Network (MFN).
On 25 January 2019, ARTC withdrew its proposed access undertaking for the interstate rail network from the ACCC's consideration.
