Do I need to reserve mountain transport trips?
Cable cars, cogwheel trains and funiculars do not need to be booked in advance, unless stated otherwise in the timetable. Special events like sunrise trips may require reservations. You would book these through the respective transport company. All regular mountain transport can be used with just a valid ticket or a rail pass (many "rail" passes are actually public transport passes and thus also include mountain transport, either for free or with a discount).
