I've got a Swiss Pass.
May I ask what sort of traction operates the RhB services between Chur-St. Moritz and St. Moritz-Tirano (not Bernina Express)?
I've created a new thread but started it off with a reference to a comment in the 'RBe540' thread from a few days ago.
Regardless of traction, the Chur St Moritz line ought to be visited this year - especially by those of us who prefer 'traditional' types of loco hauled stock, as the new Albula Gleiderzug will change the scene on the Chur - St Moritz main line, and the resulting cascade will change the scene on all the other RhB lines as well.
And, of course it's not just on RhB. The BLS and SBB are rapidly replacing their fleets with the latest genre of stock. This of course includes replacing what was supposed to be the 'new era' of stock - EWIVs and the 1980s designs - but the latter have of course become outmoded in a shorter time span than previous eras of Swiss rolling stock.
Hard to believe that the trunk east - west Swiss axis Geneva - St Gallen, the long time 'backbone' of the Swiss system, will soon be operated by EMUs!
