Caption | During the construction of the Lötschberg tunnel, the Gasterntal was originally driven under at a relatively moderate depth. This resulted in a catastrophic collapse from the surface. As a result, the route of the tunnel had to be changed considerably so that there would be sufficient superelevation when crossing the Gastern axis. This explains the winding route of the subsequent tunnel |
Caption (German) | Beim Bau des Lötschbergtunnels wurde das Gasterntal ursprünglich in relativ mässiger Tiefe unterfahren. Dabei kam es zu einem katastrophalen Einbruch von der Oberfläche her. Die Route des Tunnels musste daraufhin stark verändert werden, damit beim Queren der Gasternachse genügend Ueberhöhung besteht. Die erklärt die gewundene Streckenführung des nachmaligen Tunnels |
