The view from the visitor's window into the west tube of the Gotthard Base Tunnel in the direction to Erstfeld, 7500 meters away from the portal. These windows are available at all accesses to the tunnel and at the emergency-stops. They are not only for pleasure, and allow an overview into the tunnel before a door is opened.
