The Pilbara Infrastructure (TPI) must prepare total (maximum) and incremental (minimum) costs applicable to sections of its network for which an access proposal has been made or that the ERA considers is likely to be made. The ERA must either approve the Railway Owner's costs or make its own determination.
On 15 May 2013 Brockman Iron Pty Ltd made an application for access to use two sections of the TPI railway. On 14 August 2013 the ERA approved the commencement of negotiations between TPI and Brockman on the proposal.
