Hello. You can reserve seats on InterCity trains (IC) and most tourist trains. Trains on which you can reserve seats are marked in the timetable with an ‘R’ (reservation possible) or an ‘R’ next to a seated person (reservation compulsory). However, even on trains marked with a “R” there isn’t an option to choose your seat, (i.e. click on ‘Seat reservation’ and then on ‘Select seat’.) Am I missing a step somewhere? Thanks.
