Hello emma1116
From 14.09.2019 to 01.11.2019, a tryout Half-Fare travelcard and a tryout GA travelcard campaign will be carried out in the SBB newspaper supplements. The tryout Half-Fare travelcard is valid for two months. The tryout GA travelcard, on the other hand, is valid for one month and can be purchased in 1st and 2nd class.
The tryout offers are only available to persons who live in Switzerland or near the border.
I wish you a nice evening.
Kind regards,
FatimaH
