Whether by rail, road or air, the Swiss are highly mobile thanks to a dense transport network. Motor vehicles are the most popular means of transport here. Nonetheless, in rail travel, the Swiss are world leaders – with each inhabitant covering an annual average of 2,400km by train.
The Swiss have built several road and railway tunnels to cross the Alps along Europe's north-south axis, including the world's longest railway tunnel. In order to reduce the impact on the population and the environment, Switzerland pursues a policy of shifting freight transport from road to rail.
