in june 2010, the australian competition tribunal ruled that fmg would be granted access to rio tinto's robe river line and bhp billiton's goldsworthy line but not to the busier hamersley and mount newman lines. treasurer wayne swan suggested that several advantages would accrue from access to the rail lines by third parties. it would increase competition, reduce duplication of infrastructure, and reduce environmental damage. atlas iron, another junior iron ore miner, is hopeful to come to terms with bhp billiton in regards to using some of the company's rail infrastructure, the goldsworthy railway, in the future. bhp, in late 2010, had agreed to a joint feasibility study into how an arrangement might work.
