The intended railway route would continue from the Brünig railway line at Meiringen railway station, via the Meiringen-Innertkirchen railway, to a stop at Innertkirchen, then via new stations at Guttannen and Handegg () to Oberwald railway station for continuation via the Furka Base Tunnel. Travel time between Meiringen and Oberwald would be approximately 38 minutes—a reduction of three hours.
