Chris Tarrant: Extreme Railway Journeys

Crossing the Andes (2x2)

:

Chris continues his exploration of the world's most extreme railway lines. He attempts to cross the Andes, setting off from the coast of Chile and heading for the Bolivian capital of Sucre. Along the way he traverses some of the driest and most inhospitable environments on the planet, hitches rides on unusual trains and deals with altitude sickness at more than 3,000 metres.
