An innovative, future-oriented project
The idea of a rail tunnel on the Grimsel turned into a concrete project a few years ago. This involves the construction of a 22-kilometer tunnel from Oberwald to Innertkirchen. This would close the gap in the narrow-gauge rail network and connect the Zentralbahn with the Matterhorn Gotthard Bahn. In addition, the renewal and expansion of the Swissgrid high-voltage line over the Grimsel is imminent. For these two reasons, there is an opportunity to combine both infrastructures in a joint tunnel facility and to exploit synergies.
