The North Australia Railway was a narrow gauge railway in the Northern Territory of Australia which ran from the territory capital of Darwin, once known as Palmerston, to Birdum, just south of Larrimah. Initially its name was the Palmerston and Pine Creek Railway. The first section was opened 1889, the last in 1929. The railway closed in 1976. Beginnings – South Australian Railways Between 1863 and 1911 the Northern Territory was administered by the Government of South Australia. In 1883, that government instituted the Palmerston and Pine Creek Railway Act, which resulted in a £959,300 contract being awarded to C. & E. Millar of Melbourne. The line reached Pine Creek in 1888 and officially opened on 30 September 1889 as the northernmost outpost of the South Australian Railways. Singhalese and Indian gangs did the grubbing and earthwork and 3000 Chinese labourers laid more than a kilometre of track per day. More than 300 bridges and flood openings were built. Transfer to the Commonwealth Government As a consequence of Federation, the Commonwealth (or federal) government took ownership of the railway in 1911, having undertaken to connect Darwin with Adelaide by rail – but, crucially, without the completion date being specified. Since the federal government did not yet have its own railways department, the railway was leased back to the South Australian Government and worked as part of the South Australian railway system. World War I intervened, although in 1917 the line was extended 90 km (56 mi) to the northern bank of the Katherine River. By 1920, public interest in the idea of a north–south transcontinental railway had taken hold. However, the legal opinion of the federal attorney-general left open an interpretation that the route could be from anywhere across South Australia's northern border. Queensland interests pressed strongly for a route from the north-east corner of the state, near Birdsville, and north into the pastoral lands of Queensland before joining the existing line at Katherine River. This would involve the Central Australia Railway taking a sharp turn to the east from its established railhead at Oodnadatta for a diversion about 600 km (370 mi) east of the initially intended route through the centre of the continent via Alice Springs. The federal government referred the matter to the parliamentary standing committee on public works to examine the whole question. At the same time, it authorised an extension of the line in the
