Queensland Rail, also known as QR, is a railway operator in Queensland, Australia. Owned by the Queensland Government, Queensland Rail operates suburban and long-distance passenger services. It also owns and maintains approximately 8,000 kilometres of track in Queensland.
Queensland Railways was the first operator in the world to adopt narrow gauge (in this case 3 ft 6 in (1,067 mm)) for a main line,[1] and this remains the systemwide gauge within Queensland today.
