The Lauterbrunnen-Mürren mountain railroad (BLM), which belongs to the Jungfraubahn Holding, consists of an aerial cableway from Lauterbrunnen to Grütschalp and a meter-gauge adhesion railroad a good 4 kilometers long from Grütschalp via the Winteregg crossing station to Mürren. StadlerRail is supplying three new Be 4/6 # 101 to # 103 double railcars for the Grütschalp-Mürren line. The first vehicle # 102 was delivered in October 2023 already for tests. On 13 and 14 May 2024, the two car bodies of train # 101 "Eiger" were transported by special transport from Lauterbrunnen (797 meter a.s.l.) via mountain roads to Winteregg (1578 meter a.s.l.), where they were mounted on the bogies. The first car of train # 101 is ready in Winteregg to be unloaded from the Castor+Pollux transporter to the bogies, which were placed on the track already. The catenary was removed temporarily here.
