Queensland Rail was subject to the 2008 access undertaking the QCA approved for QR Network, as amended to include new tariffs and tariff-setting rules in June 2010. The undertaking applied to Queensland Rail through a Transfer Notice published by the Queensland Government in June 2010 under the Infrastructure Investment (Asset Restructuring and Disposal) Act 2009. The 2008 undertaking expired on 30 June 2015.
The access undertaking set out the terms and conditions under which Queensland Rail provided access to rail infrastructure covered by the undertaking. It also set out the process required for an access seeker to negotiate access to the infrastructure and how any disputes in relation to access were to be resolved.
