I’ve been checking for weeks and also searching the other answers on this help board and the only information I’ve been getting is replies to others saying ’it’s common for the train bookings not to be available yet because Trenitalia don’t update their timetable until June’. I’ve followed that advice so far, so disappointed that it’s not been good advice.
Where did you find that the EC34 is not running the full route those days? I checked all the official swiss PDF timetables last week and it never said anything.
