From meeting a "therapy elephant" in Malaysia to swimming in freezing seas inside the Arctic Circle, Nick Knowles is off to visit the wonders of the world by train. Over five fantastic globe-trotting journeys, he immerses himself in the people, landscapes and cultures of Mexico, Alaska, Vietnam, Malaysia, and Norway, hopping aboard incredible trains as he embarks on some of the most breath-taking railway journeys in the world. In Mexico, he takes a magical trip on El Chepe, the Copper Canyon railway, 66 years in the making and a remarkable feat of engineering. Then in Alaska, the train to Fairbanks stops in Wasilla for a trek to the Matanuska Glacier. And in Vietnam, he takes the night train from the Chinese border, rolling into Hanoi as dawn breaks. This rich, high-octane series is a sparkling exploration of incredible railway engineering, mind-blowing vistas and the rich heritage of each of the countries he visits.
