Hi Matthew -
Welcome to My Swiss Alps
The Golden Pass route is one of many excellent scenic rain rides -

You can take luggage on board. You can also ship it, depending on your schedule. More on that if you let us know you are interested.
Don't know about a push chair...is that the same as what we call a wheel chair in the USA?
There are different types of rail cars on the Golden Pass trains, on certain segments of the line, some with special windows or seating arrangements on some of those trains. That might influence the transport of a wheelchair.
Perhaps Arno can suggest a link to help clarify that point.
<<"Do you suggest that I stop in every location where the train stops and have a look around?">>
Check the timetable:
and after you select a particular journey , click on the "+" to the left. Then, click on "intermediate stops." There a can be a lot, on some trains.
The train stops will be brief.. a small number of minutes. You could wait for the next train, typically one hour later...
<<"Do I need to book each and every leg from Luzern to Montreux individually?">>
To travel on that route, or most Swiss trains with the country, you do not need to book or make reservations. However, see the Golden Pass link above....the special scenic and panoramic cars probably need booking.
I don't comment on rail passes...I leave it to the experts, Arno and Annika.
