Chris Tarrant returns for more tretcherous journeys on the world's most extreme railways
For Chris Tarrant, travelling by train is the best possible way to explore a country, meet the real people and unlock its culture and history.
In the third series of Extreme Railways, he explores the Alaska Railroad, sets out from a British-built station in Buenos Aires, travels 1500 miles from Cape Town, South Africa to the Victoria Falls in Zimbabwe, travels the route of the Soviet-era Trans-Caucasus Railway departing the capital of Azerbaijan, Baku and ending with an epic journey through Scandinavia and traveling to Rovaniemi in Finland, know as Santa's home town.
