Hello
@SG-Opfiker First of all, I would like to draw your attention to the fact that we also have an English community. So next time I ask you to change the page language to get to the English community. This way other users with the same problem can also see the answer they are looking for.
Railchecks can generally not be extended. If you have a medical certificate of incapacity to travel, an exception may be possible. For this, please contact directly the place where you received the Railcheck or go to a serviced SBB sales point. However, I can not promise you the extension. The decision is at the discretion of the SBB sales point.
Thank you for your understanding and I wish you happy holidays.
Kind Regards, VlaznimA.
