in HISTORY its says " Unlike BHP, which controls its trains from Port Hedland, Fortescues trains are controlled from Perth.[1] The line is open-access, meaning Fortescue is willing to allow other mining companies to use it for their operations.[4] "

However FMG has the huge Solomon Hub
Solomon Hub
Centrally located in the middle of Fortescue’s 87,000 km2 (34,000 sq mi) Pilbara tenement area, the Solomon Hub is Fortescue's next major project. It has almost twice the resource and less than half the strip ratio of the Chichester Hub. Fortescue’s Exploration team has already delineated more than 2.86 billion tonnes (2.81×109 long tons; 3.15×109 short tons) of resource at the Solomon Hub and there are identified exploration prospects targeting up to 5 billion tonnes (4.9×109 long tons; 5.5×109 short tons). A detailed feasibility study outlining plans for the Solomon Hub will be delivered late 2011. Developing the Solomon Hub is part of Fortescue's plan to reach a target of 155 million tonnes per annum (Mt/a) in 2013 and the "Three Hubs, Two Ports" strategy involving building the new Anketell Port.[2]
