World's Most Dangerous Railways

From Chur, Switzerland’s oldest city, to Tirano in Northern Italy, the Bernina Express winds its way through deep valleys and wild gorges, crossing some 196 bridges and going through 55 tunnels in its journey through the Graubünden Alps. A journey to discover one of the most spectacular railway lines in the world and an audacious feat of engineering.

The Tanzania-Zambia-Railway (Tazara) is one of Africa's most ambitious infrastructure projects; it connects the inland with the coast of East Africa and meant independence from the surrounding apartheid-ruled countries of East Africa.

The Rameswaram Express takes twelve hours to link the coastal city of Chennai in eastern India with the pilgrimage town of Rameswaram in the far south. Passengers cross bird sanctuaries, rice paddies, the sacred Kaveri River and the spectacular Pamban Bridge.
