Cameras focus on the island of Taiwan, and three extraordinary railways. The journey begins in the eastern port city of Hualien, from where we travel north along the rugged Pacific coast. The trek ends with a view of Taiwan's highest mountain peaks above a sea of clouds.

Cameras follow a train route from Bergen to Oslo, through the extraordinary mountains of southern Norway in winter. This super-fast train travels daily to the country's capital, and first stop is Dale - a place where Norway's most famous knitters design and craft the country's famous jumpers. The final stop is Sandvika, where Monet painted around 30 scenes.

Cameras focus on Austria's stunning Transalpine railway, which crosses the snowy peaks of the Tirol. Our journey begins in the historic city of Graz and heads west through famous alpine beauty spots, including Zell am Zee, where the sounds of yodelling still echo across pristine mountain valleys. The final stretch passes through the 10.6- kilometre Arlberg Tunnel.
