The panoramic trains on the Golden Pass route run on the Montreux to Zweisimmen section (not all trains are panoramic on this route).
All trains between Interlaken and Lucerne are similar to a panoramic train (larger windows) but not quite the same.
If you search the timetable here, the trains on the Montreux to Zweisimmen route that are panoramic are listed as MOB Panoramic (modern train) and MOB Belle Epoque (heritage train).
