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 via mountain roads to Winteregg, where they were mounted on the bogies. The special vehicle "Castor + Pollux", which belongs to the company Mountaintrans AG, was used for the transport. Von Rotz & Wiedemar Seilbahnen in Kriens, in collaboration with Wipfli Transporte AG, is responsible for the know-how, operation and maintenance. The special transport branches off the main road in Lauterbrunnen onto the Zuben mountain road in the direction of Winteregg. The 7,5 kilometer long journey up to the Winteregg needed 4 hours.
