Hi there, I’m looking to take the train from Berlin to Warsaw in October and I need a seat reservation. On interrail, it says i will receive a paper ticket if I try and book it. The thing is, I’m leaving shortly and won’t be able to receive it before I leave. Is there any way to have it as an e-ticket?

Also, I checked on the DB website (the train. company that operates the train I want to take), but I don’t see any option to reserve a seat without the whole ticket (there are still tickets available btw), and on OBB it says “ticket not available”… I would really need a reservation for this specific train and I don’t know how to do it, please help. Thanks so much!
