Traduction automatique. Texte original en: EN - afficher l'original The Bsi 291 - 293 2nd class interface cars, which are designed for a 1'435 mm gauge only, are coupled to the non-powered multiple units. The interface cars are necessary for mechanical coupling, as the couplings on the MOB vehicles are at a different height from the screw couplings and buffers on the BLS locomotive, and will also allow communication between the other GoldenPass Express (GPX) coaches and the Re 465 locomotive.

These interface cars are of the same design as the other coaches, so they do not imply a quality drop in travel comfort for passengers. In addition, this interface car (linked by a screw coupling to the Re 465 locomotive) is connected to the other coaches by an automatic coupling with an electric and pneumatic head. / Sources: https://www.railvolution.net/news/goldenpass-express-at-the-start
