Aurizon Holdings Limited is a freight rail transport company in Australia, formerly named QR National Limited and branded QR National. In 2015, it was the world's largest rail transporter of coal from mine to port. Formerly a Queensland Government-owned company, it was privatised and floated on the Australian Securities Exchange in November 2010. The company was originally established in 2004–05 when the coal, bulk, and container transport divisions from Queensland Rail were brought under one banner as QR National. In 2019, the company operated in five Australian states; on an average day it moved more than 700,000 metric tons of coal, iron ore, other minerals, agricultural products and general freight – equating to more than 250 million tonnes annually. Aurizon also managed the 2670 kilometres Central Queensland coal network that links mines to coal ports at Bowen, Gladstone and Mackay; it was the largest haulier of iron ore outside the Pilbara. In 2021, a major corporate change was foreshadowed when Aurizon sought to acquire rail operator One Rail Australia. Wikipedia
