Its main purpose is to increase total transport capacity across the Alps, especially for freight, notably between Germany and Italy, and more particularly to shift freight volumes from road to rail to reduce environmental damage caused by ever-increasing numbers of heavy lorries. A secondary benefit will be to cut the journey time for passenger trains from Zürich to Milan by about an hour and from Zürich to Lugano to 1-hour 40 minutes.
