Edit: yes, this will use at least one of your 2 inbound/outbound journeys.

I will travel on the 17th of August with the nighttrain from Zürich to Budapest.

On the mobile new style app: you can use 2 days of total IN your own country, it may give proibs as its overnite for next day leg.

On old-style paper: have to fill out special field for OUT and IN-probably both in this case.

Ok thanks. I thought it wouldn’t count because i don’t leave the train in my country. I only cross it. That makes it more complicated.
