Transportation
Because of the comparatively easy topography and the dense population, the transport network is highly developed. The most important transversal, so to speak the backbone of the Swiss Plateau, is the A1 motorway that connects all the big cities going from Geneva over Lausanne, Bern, Zurich and Winterthur to St. Gallen. The A2, the Swiss north-south axis, crosses the plateau from Olten to Luzern.
The railway network is very dense. All major cities are connected, and between Olten and Lausanne there are two main lines: One passing over Bern and Fribourg, the other passing over the edge of the Jura with Solothurn, Biel, Neuchâtel and Yverdon-les-Bains. The train ride from Zurich to Bern takes one hour; crossing the entire Swiss Plateau from St. Gallen to Geneva takes four hours.
The two most important Swiss airports are situated in the plateau, Zurich International Airport and Geneva Cointrin International Airport. The capital of Switzerland, Bern, has only a small airport, Bern Belpmoos Airport.
