Aurizon Holdings Limited is a publicly listed rail freight company in Australia. Formerly owned by the Government of Queensland, its assets were transferred to a new company, QR National Limited, in July 2010 in preparation for it being floated on the Australian Securities Exchange in November 2010. Aurizon is Australia's largest rail freight company.
QR National was established in the 2004/05 financial year when Queensland Rail's coal, bulk and containerised business units were brought under one banner. It was formed with the charter to operate freight services in Queensland and around Australia, expanding though the winning of contracts and the acquisition of other companies. QR National was rebranded as Aurizon in December 2012.
