The 'Goldenpass' is a brand name invented for tourists. The true 'Golden Pass' is only the mountain section between Montreux and Chateau d'Oex, on the MOB railway route.
Interlaken - Luzern is not truly the GoldenPass. It is a separate railway called the Brünig Pass. It used to be part of Swiss Federal Railways but is now run by a joint operation known as Zentralbahn.
The trains on the line are now dubbed Luzern Interlaken Express. They have plenty of seats and no reservation is required
