The last selling point is often the sheer convenience of leaving and arriving in a fully connected train station right at the heart of your chosen city, rather than on the outskirts of your destination. The International Transport Forum reports that the average CO 2 emissions of high-speed trains in Europe per passenger/km stand at less than 17g, compared with 153g for planes. What’s more, for those passengers who are conscious of their environmental footprint, research has repeatedly shown that train travel is the least polluting way to cover long distances: a train generates up to ten times less CO 2 than an airplane, according to Rail Europe.
