Railroad Australia discovers just what it takes to transport ever-growing numbers of passengers and crucial resources across one of the most extreme and hostile places on the planet. In a wild frontier world of blistering heat and vast distances, an army of workers toil day and night to keep the nation's lifeblood flowing... with a little help from some of the biggest and most powerful trains in the world. Australian rail operators are world leaders in heavy haul rail freight, moving some of the longest and heaviest freight trains in the world. From two kilometre-long freight monsters to the super sleek long-distance 'hotels-on-wheels', outback trains are crucial to Australia's biggest industries and the very survival of many remote communities. With unprecedented access, Railroad Australia goes behind the scenes to discover train drivers, locomotive servicing crews and track maintenance teams on some of the toughest, most demanding and spectacular journeys.
