It's confusing to have multiple posts with the same topic. Perhaps you did so in error?
Use the SBB app for train travel in Switzerland. This app will answer all your Swiss questions.
Safe travels.
The Swiss Rail site including the app is easy to use- sbb.ch
The “fast “ train is the TGV Lyria, www.tgv-lyria.com from Paris to Zurich. Best fares are booked furthest out. We found the Swiss trains easy to use and the scenery beautiful.
If you are travelling Tirano - Zurich - Paris in one single day you should just book a ticket Tirano - Paris with SBB.
