How can I save a travel day when traveling with a night train?
If you're travelling on a night train that arrives after midnight, you only need to use a travel day for the day of departure. The app will automatically only use one of your travel days when you add this journey to your Pass. Keep in mind that the arrival day of the night train needs to fall within the validity of your Pass.
If you change onto another train and keep travelling after your night train arrives, you will need to use another travel day. The app will automatically ask you to use another travel day when you add this journey to your Pass.
