You could travel the length of India by rail, take the narrow gauge route along Spain’s rugged north coast, or experience the world’s highest railway in Tibet. For cutting age railway technology, why not ride on the Shinkansen, Japan’s ‘bullet train’, which will take you to 320 kilometres per hour? Or for a complete contrast jump aboard a narrow gauge ‘Toy Train’ in India, which hauls you up to a traditional hill station at little more than walking pace.
In Norway you can experience the phenomenal engineering of the Flam Line, the steepest standard gauge railway in Europe, and in Russia you can travel on the historic Moscow to Saint Petersburg Railway, one of the oldest and most famous routes in the world.
