Intermodal train southbound to Italy on Gotthard line after crossing the Biaschina gorge and passing two spiral tunnels near Giornico, Canton Ticino, Switzerland

Visible are train tracks on 3 levels (spiral tunnels between them), the Biaschina-Viaduct of the A2 Gotthard-Autobahn (top left) and the hairpin-bends of the Kantonsstrasse 2 (center right)

This photo portrays complex structures

• heavy trains need 2 locomotives to pass the steep line
• international trucks crawl up the highway to the roadtunnel (truck traffic tenfolded since the opening of the Gotthard roadtunnel)
