From Winnipeg to Churchill, in Manitoba, the route travels through grasslands, Canada's Boreal Forest and almost into the frozen Arctic Circle. It's a constant task for engineers to overcome snow, ice and temperatures as low as minus 45.
In the heat of Mexico, the prestigious luxury El Chepe train is a wonder of Mexican engineering. It has taken almost 100 years to build and perfect the the route through the world's largest canyon region, Copper Canyon.
One of only a few steeply graded narrow guage lines in the world, The Darjeeling Himalayan Railway connects New Jalpaiguri, Eastern India, to Darjeeling at the base of the Himalayas. It features a century old steam loco, amongst others.
The Ghan, is Australia's most luxurious train. It crosses from Adelaide to Darwin. In a 2 day trip, it experiences heat, risk of animal collisions, and weather events. A virtual army of engineers run the Ghan and its 3,000 kms of track.
The Bergen line runs from Bergen to Oslo, in Norway. Along the fjords of Western Norway, up to the Hardanger, and through deep forests, it takes a team of people to keep the line open in snow, wildlife and repairing damaged trains.
