As on the title, can I get a discount for Mountion rail like ZBAG(Zermatt Bergbahnen), BGF(Bergbahnen Grindelwald–First), BET(Bergbahnen Engelberg–Trübsee–Titlis AG) or JB(Jungfraubahn) by Half-price travel with saver day pass or special 1-day travelpass?? I am confusing, because on the synoptic map it seem like only Half-price travel with GA/seven25 travelcard can get a discount. And if I can get a discount, its discount rate would be 50%?
