Are you not sure what the "Additional supplement required" notification means on our seat reservations tool or timetable? Don't worry; you can still board these trains with your Pass; however, you need to buy an additional supplement to board the train.
A supplement is a mandatory fee required by certain railway companies in order to board specific trains. This fee must be paid either at the station or onboard the train.
In some cases, it may also be possible to purchase the supplement in advance online or by buying a seat reservation for the relevant train.
The trains listed here are the only trains that require an additional supplement: Trains with additional supplements
Please read this page carefully! The supplement amount, information, and how to get a supplement differ for each of these exceptions.
If you are not sure whether a supplement is required on your route or are unsure how to purchase it, feel free to contact our Customer Service team for assistance.
