The Pichi Richi Railway is a 39 kilometres (24 miles) narrow-gauge heritage railway in the southern Flinders Ranges of South Australia between Quorn and Port Augusta. For much of its length the line lies in the picturesque Pichi Richi Pass, where the line was completed in 1879 as work proceeded north to build a railway to the "Red Centre" of Australia – the Central Australia Railway. The Commonwealth Railways ran trains through the pass until 1980, when it ceased its by then meagre services. A newly built extension to Port Augusta was opened in 2001.
