QR National Limited is one of the larger rail freight companies in Australia and was formerly owned by the Queensland Government. It was created as an independent company on 1 July 2010 when transport and logistics company QR Limited was split into two companies. Queensland Rail is responsible for the state’s passenger operations, regional track and support services, and remains owned by the Government. QR National owns the balance of the QR business – above-rail coal and freight services, the export coal network in Queensland and rollingstock manufacturing and track maintenance services.

There are plans to change QR National's name to Aurizon.
