1) I'm worried about burn out - your schedule seems extremely non stop. Take care to add in 'rest days'
2) Some days trips look too long to me. They may be possible on paper travel time wise, but don't forget to add in the time spent to see the attractions you want to see you get there.
For example: "Day trip to Montreaux, Lausanne, Geneva (Chateau de Chillion, Callier Chocolate factory, Olympic Museum complex) – Golden Pass train" is a huge amount for one day
3) take care not to be drawn all the time to the branded 'special trains' - all trains in Switzerland are efficient, fast (depending on landscape of course) and give good views.
"Day 7 (Jun 21) – Interlaken to Zermatt (Train - Golden Pass then change train Speiz to get the Regio Express and then at Brig to Zermatt?):
On this route Interlaken - Spiez is a short journey and can be done on any train including the local services . From Spiez it is either over the Lotschberg mountain line to Brig, then MGB to Zermatt, or fast train through the base tunnel direct to Visp (change for Zermatt)
4) You will have seen plenty of high mountain territory on your trip, so in my opinion your idea to do Zermatt - Glacier Express - Gotthard - Lugano is really worth it you will only do half the Glacier Express route (with extra fare) and the southern half of the Gotthard route (with extra fare). To get from Zermatt to Ticino if I were you I would go Zermatt - Domodossola - Centovalli - Locarno - Lugano.
5 ) Also 1 day in Ticino (Lugano) is rather short compared to all the time you will spend in mountain areas
