Railway in the desert of Australia

This is a photo of the railway that runs through the centre of Australia from Adelaide to Darwin. It is used by The Ghan, which is an Australian passenger train service between the cities of Adelaide, Alice Springs and Darwin. Starting in August 1929, The Ghan ran on the Central Australian Railway, originally built as a narrow-gauge railway to Alice Springs. In 1957, the standard gauge Stirling North to Marree line opened, and the Ghan was curtailed to operate only north of Marree. In October 1980 the remainder of the line was replaced by a standard-gauge line built to the west of the original line. An extension north from Alice Springs to Darwin opened in January 2004. This photo was taken in the South Australian desert, somewhere between Glendambo and Coober Pedy.
