Dibrowne Yes, on any train with the same itinerary. Assuming the ticket details clearly say “point-to-point”, which is typical for longer journeys.
With shorter single journeys within a regional fare network (e.g. ZRH Airport - Zurich City), you would get a zone ticket with a shorter validity period between 1h and 3h. In this case you could also take any means of transportation within the listed zones and the validity period (e.g. the following connection).
The only ticket type tied to a particular connection are the Supersaver tickets.
So simply select a ticket for your planned itinerary/connection and check the validity period details before hitting the “buy” button.
