Access tunnel to the Lötschberg base tunnel of the new railway link through the Alps (the NRLA - New Railway Link through the Alps [NEAT - Neue Eisenbahnalpentransversalen in German, NLFA - Nouvelles Lignes Ferroviaires à travers les Alpes in French] or AlpTransit project) from Goppenstein, but named "Fensterstollen Ferden" or "Zugangsstollen Ferden" because the main cavern is located deep in the mountain, almost below the village of Ferden in the Lötschen valley. Used as one of the main entrances during construction, this 4.1-km-long access tunnel then became an emergency tunnel for rescuing passengers from a train in case of fire.
The tunnel mainly penetrates gneisses, schists and amphibolites of the pre-Variscan crystalline basement and to a lesser extent sedimentary rocks and conglomerates of the Ferden Carboniferous zone, and also Mesozoic sedimentary rocks of the so-called Jungfraukeil (Jungfrau wedge).
