Mighty Machines

One train. One driver. 3,000 tons of timber a day. Timber hauling is big business for Sweden's economy, and it takes a mighty train and some strong-willed men and women to pull it off.

Just off the coast of Malaysia, the ultimate heavy-lift pipe laying vessel, Sapura 3500, has just three short weeks to build an offshore gas platform in the South China Sea.

It's one of the most beautiful journeys on earth – especially in the winter. Traveling along the highest rail line in Europe, this passenger train navigates 55 tunnels, nearly 200 viaducts and bridges.
