Queensland's Railways
- QGR/QR/QR National: The original and dominant 'mainline' railway, and currently (2009) owner of the state's 1067mm rail infrastructure. QR National has most of the coal hauling contracts in Queensland and operates rail services in several other states.
- Pacific National: Operates containerised traffic in the main north-south coastal corridor, and operates rail services in several other states.
- Smaller Operators: Railco, the Savanahlander and others have scheduled tourist-oriented services on QR or ex-QR trackage.
- Heritage Operators: A variety of organisations, including QR, operate heritage railway services on QR track, generally on an occasional basis, although Mary Valley runs several services each week on dedicated ex-QR track. Museums and related organisations (ANGRMS, Archer Park, ASCR, Whistlestop, etc.) provide regular railfan/tourist-oriented services, typically either weekly or monthly, on dedicated trackage.
