I have a sleeper train booked from ljubliana to budapest on 26/08/23 leaving at 00:30.
I will be in zagreb on the 25 and was planning on getting the 19:30 from zagreb to ljubliana to arrive at 21:47. However I can seem to reserve a ticket, I can’t tell if it is fully booked or not as OBB says its unavailable and so does eurail. I tried both croatian and slovenian rail companies website but I couldn’t find the journey. Will I be able to book this at the station or is it fully booked and I have to find an alternate route?
