I booked two tickets on the direct Deutsche Bahn (ICE 93) train from Berlin to Vienna and the seat information is shown as - "Side-by-side seats Carriage 27, seats 13, 15". I would normally have expected the seat numbers to be continuous, e.g. "13, 14" or "14, 15", although I have never travelled by train in Germany so do not know the seat number system.
I booked the tickets via Trainline EU and I asked them. Their reply was:
Unfortunately, we don't have access to the seat plan of this train, so there is no way for me to confirm or deny if you are next to each other. Usually, when you're booking for multiple passengers at the same time, the system automatically tries to put them together(if possible), or the at the very least close to one another.
Could someone confirm that the seats are indeed side-by-side (and also not separated by the aisle)? Also, if anyone could show the seats on a seating plan that would be helpful.
