Queensland Rail (QR) is a railway operator in Queensland, Australia. Owned by the Queensland Government, it operates local and long-distance passenger services, as well as owning and maintaining rolling stock and approximately of track and related infrastructure. History Beginnings Queensland Railways was the first operator in the world to adopt narrow gauge (in this case ) for a main line, and this remains the systemwide gauge within Queensland today. The colony of Queensland separated from New South Wales in 1859, and the new government was keen to facilitate development and immigration. Improved transport to the fertile Darling Downs region situated west of Toowoomba was seen as a priority. As adequate river transport was already established between the capital Brisbane and the then separate settlement of Ipswich, the railway commenced from the latter locality and the initial section, built over relatively flat, easy country opened to Bigge's Camp, at the eastern base of the Little Liverpool Range, on 31 July 1865. Called the Main Line, the only significant engineering work on that section was the bridge over the Bremer River to North Ipswich. Tunneling excavation through the Little Liverpool Range delayed the opening of the next section to Gatton by 10 months, but the line was opened to Toowoomba in 1867, the ascent of the Main Range being the reason for the adoption of narrow gauge. Built by the Queensland Government to the unusual (for the time) gauge of , the line largely followed the alignment surveyed by a private company, the Moreton Bay Tramway Company, which had proposed to build a horse-drawn tramway but had been unable to raise funds to do so beyond an initial start on earthworks. The adoption of narrow gauge was controversial at the time, and was largely predicated by the government's desire for the fastest possible construction timeframe at least cost. This resulted in adoption of sharper curves and a lower axle load than was considered possible using standard gauge, and an assessment at the time put the cost of a narrow gauge line from Ipswich to Toowoomba at 25% of the cost of a standard gauge line. In a colony with a non-indigenous population of 30,000 when the decision was made, it is understandable. The network evolved as a series of isolated networks. It wasn't until the completion of the North Coast line in December 1924 that all were joined. The exception was the
