Some users on Twitter but also here in the community have the problem that they do not get informed about the fee to use the DB-ÖBB Eurocity trains to/in Italy. The railplanner app gives some time ago the (wrong) information that you need a reservation, now it writes nothing. The problem now is that DB-ÖBB started to ask an additional fee if you pay the fee on the train.
Would be possible to add a notice like please check the special conditions to use this train or something like this? Because how we know only with an Interrail/Eurail Global Pass and an Interrail/Eurail One Country Italy Pass you have to pay, with an Interrail/Eurail German Rail Pass not.
On the Railjet trains Venice-Vienna, there is the compulsory reservation notice, but like via Brenner there is only a compulsory fee needed. Here is the information wrong about the compulsory reservation also on the website. If I am not wrong, you get via Interrail Reservation system only the fee and not a reservation.
On the Eurocity EC135 Trieste-Ljubljana that continues as EC150 as Ljubljana-Vienna (the app shows as connection with a train change wich is not so in that case). Same in the opposite direction with EC 151 and EC 134. Here there is also a compulsory fee to be paid for Interrail users, and this is 2,60€.
