I'm trying to book a night train from Zürich to Amsterdam, but it seems to be impossible. I am able to find a train called 'Nightjet 402', but when I try to get tickets to it using ÖBB app, it just says 'ticket not available'. I have tried many other apps and websites, too. And I have tried many different dates.
Do I have to get tickets to that train at the train station? Or is there some way to book those in advance (seat reservations or tickets)?
(I have interrail global pass)
