Hello sanya14
Thank you for your inquiry.
If you buy a point-to-point ticket, you are not train bound. There you have the possibility to start this journey from 00:00 o’clock until 05:00 o’clock the following day. For the return trip on the next day you can buy such a ticket again.
We still offer supersaver tickets. These are slightly cheaper, but train-bound. If you buy a saver ticket, you have to take the train you bought (refund and exchange only possible in exceptional cases for a fee).
You can find information about a point-to-point ticket here: sbb.ch/travelcards-and-tickets and information about the supersaver ticket here: sbb.ch/travelcards-and-tickets
If you have any questions, we are here for you. Have a good start of the week.
Greetings ZoeS
