Numerous narrow gauge railway lines were built in Oceania, most in , and track gauge. == Australia == (詳細はTasmania, Western Australia and parts of South Australia adopted gauge to cover greater distances at lower costs. Most industrial railways are built to gauge. Three different rail gauges are currently in wide use in Australia, and there is little prospect of full standardisation. Before 1901, each of the six British colonies was responsible for rail transport infrastructure. Queensland, Western Australia, and Tasmania constructed for narrow gauge railways. The other colonies built either standard gauge or broad gauge railways, maintaining only limited narrow gauge rail lines, except for South Australia, which built both narrow and broad gauge. As a result of this legacy, Australian railways are a mix of all three gauges. In 1865, the Queensland Railways was the first mainline narrow gauge railway in the world. Its tracks would eventually extend to around 9000 km. Queensland Rail operates the QR Tilt Train, with a maximum speed of 165 km/h. This train currently holds the Australian Railway Speed Record of 210.7 km/h. Queensland also has extensive sugar cane tramways of gauge. Following the success of the narrow gauge in Queensland, several narrow gauge lines were built in South East Australia. From the 1920s onwards several of these were converted to broad gauge. The first of these was the Port Wakefield Railway of 1867 where it was claimed that the cost of a railway varied with the cube of the gauge. Inspired by the success of the narrow gauge in Queensland, Western Australia adopted the same gauge. Until closure in 1958 Perth had the only narrow gauge tramway network of any considerable extent in mainland Australia. The Northern Territory adopted narrow gauge when it was still part of South Australia, and a North-South transcontinental line was planned from Adelaide to Darwin in the 1870s. In the event this line was never completed, and due to flood damage and lack of traffic, the narrow gauge line was closed. Tasmania converted to an all gauge system in 1886, but introduced narrower-still to reduce costs even more. Four common carrier lines in Victoria were built to the narrow gauge standard, to serve local farming and forestry communities. Sections of two lines (Belgrave to Gembrook and Thomson to Walhalla) have been restored as tourist railways. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Narrow gauge railways in Oceania」の詳細全文を読む スポンサード リンク
