The first passenger train ever to cross the Australian continent from north to south left Adelaide on Sunday.
The mile long train rumbled off for the three day journey to Darwin, cheered by thousands of Australians.
The railway which had been planned for 140 years was only half completed until this year.
Described as one of the world's greatest train voyages, it passes through forbidding desert country known as the Never Never.
The Never Never Train
"It was nicknamed the 'Never Never train' because of where it was supposed to go and because they thought it would never happen ," said a local politician.
