The Ghan is a passenger train operating between Adelaide, Alice Springs, and Darwin on the Adelaide-Darwin railway in Australia. The journey takes 48 hours to travel the 2,979 kilometers (1,852 miles). The service's name is an abbreviated version of its previous nickname The Afghan Express, unofficially bestowed on the "express passenger" service of the Commonwealth Railways in 1923, by one of its crews.
