Mighty Trains takes viewers inside Great Southern Rail's enormous Adelaide warehouse where everything from toilet paper to truffle oil has to be precisely inventoried and stored for the long trip north.The train is equipped with a special motorail car to transport passenger's cars when they vacation across country or are moving from one part of Australia to another.We take a special trip on the Pichi Richi Railway – a narrow-gauge tourist line operating along the original Ghan route, where flash floods and rocky terrain made for difficult travel. The Ghan moved its tracks further west in 1956, but the Pichi Richi Railway offers tourists a trip on an original steam locomotive train to experience what Ghan travel was like a hundred years ago.
