mm (5 ft 3 in) gauge line from Adelaide to Port Adelaide. The three major Australian colonies at the time failed to follow advice from the British Government to adopt a uniform gauge in case the lines of the various states should ever meet. In 1850 the original Irish engineer, Francis Sheilds persuaded the Government of New South Wales to require that all railways in the colony be of the Irish broad gauge. In 1853 a Scots engineer persuaded the legislature to change back to standard gauge. Unfortunately although New South Wales had informed Victoria of the change, the government there decided to continue with gauge and South Australia then followed Victoria. Suggestions and proposals respectively that Victoria should follow New South Wales or New South Wales should convert to the Victorian gauge were made soon after but the states followed their initial choice. Queensland's first line ( gauge—known in Australia as "narrow gauge") from Ipswich to Bigge's Camp, the first stage of a railway between Brisbane and Toowoomba, opened in 1865. This gauge was intended to save money and was subsequently followed by Tasmania and Western Australia. As a result, in the middle of the 20th century Australia had almost equal amounts of each gauge. Tasmania's first gauge line opened in 1871 from Deloraine to Launceston and was converted to gauge in 1888. Finally, Western Australia opened its first Government-owned line in 1879 between Geraldton and Northampton. Lines spread in all the states from these first lines, connecting ports to farmland and ports. The mainline systems of New South Wales, Victoria, South Australia and Queensland met (albeit with three breaks of gauge) in the 1880s. Only Victoria and South Australia shared a common gauge, and even so they opted to change engines at the border. The other mainland colony, Western Australia, was isolated by 2,000 km of desert. The first break of gauge was created when the New South Wales and Victorian lines met at Albury in 1883. The railways of Victoria and South Australia meet at Serviceton in 1887, but these lines were both broad gauge. In 1888 the railways of New South Wales and Queensland meet at Wallangara. Meanwhile, in 1889, the first line ( gauge) in the Northern Territory was opened from Darwin to Pine Creek. In 1914, an eight kilometre extension of the New South Wales Railways from Queanbeyan to Canberra was opened to create
