The Adelaide–Darwin railway line is a railway line in Australia, between the South Australian town of Tarcoola and the Northern Territory city of Darwin. Preceded by a number of other shorter railways, a line through to Darwin was fully realised in 2004 when the final link from Alice Springs to Darwin was opened. Forming the main section of the 2,975 kilometres (1,849 mi) rail corridor between the cities of Adelaide and Darwin, the line is used by The Ghan passenger train and interstate freight trains operated by Aurizon.
