Overview:Scott briefly visits Cook before arriving in Kalgoorlie, Western Australia, home of historic gold rushes and a pivotal location for Western Australia's rail history. After a quick stop in Perth, it's off south to timber country and the Hotham Valley railway. Here he is put to work priming steam engines for the Pinjarra to Dwellingup tourist trip. Pibara, in northern Western Australia, is Scott's next destination, where he gets a lift on one of the longest and heaviest trains running on the planet.
