In this episode, it's a journey unlike any other, as we travel in a train made up of 18 vintage coaches on an epic 10-day expedition. Starting from one of the world's most remote cities, Walvis Bay in Namibia, we roll 1,500 miles through the Kalahari Desert to Pretoria, the executive capital of South Africa. On the way, we hunt waterbuck with the San people, one of Southern Africa's oldest peoples. We learn how a sheepdog can protect a flock from the world's fastest killer, the cheetah. And crossing into South Africa, we make brandy in a desert oasis, before visiting the ‘Big Hole', once the most productive diamond mine in the world, a place where the fortunes earned changed the face of Africa. Finally, arriving in Pretoria, we learn how one man, Nelson Mandela, helped heal centuries of bloodshed that scared these beautiful lands.
