Fortescue Metals is considering another appeal after losing its battle to access Rio’s iron ore rail line in the Pilbara.
The Australian iron ore miner had been fighting for access to Rio's Hammersly and Robe River lines for six years.
However the Australian Competition Tribunal has ruled that Rio’s Hamersley and Robe rail lines should not be opened up to other users.
Fortescue chief Nev Power said it was ''regrettable that the Competition Tribunal did not see the merits of providing third-party access to this infrastructure to enhance competition and thereby deliver greater productivity and efficiency benefits for all of Australia'," SMH reported.
''Fortescue will continue to provide third-party access to our own rail system and will continue to advocate for third party access for all Pilbara rail infrastructure,'' Power said.
The company said the tribunal’s decision would not affect its current operations or expansion plans, but conceded an appeal may be considered to sure up future options.
Rio Tinto Iron Ore acting chief executive Paul Shannon welcomed the decision.
“This is great news. Rio Tinto runs a highly efficient railway that is fully integrated with our port and mine operations. This would be severely hindered if third parties were allowed to run trains on our rail network, not to mention the knock-on negative effect on the Western Australian and national economies from creating such inefficiencies.”
