Aurizon operates rail haulage of coal, iron ore, and freight, and owns a regulated rail network in Queensland. Coal haulage from mine to port contributes a third of operating income. The noncoal bulk segment contributes less than 15% of earnings and undertakes the rail haulage of agricultural, mining, and industrial products. The rail network, composed of 2,670 kilometers of coal rail network under a 99-year lease from the Queensland government, contributes half of earnings.
