On my trip from Budapest to Pula the overnight part goes from Budapest to Divaca. Before midnight the tickets of all travellers in my coupé where checked and approved. After midnight we where checked again and no one of us 3 was able to show the ticket to the inspecteur.
Since I have to change trains my trip was already split in 2 parts. I showed my ticket for day 2. It was accepted.
Both other travellers were on their way to Ljubljana. They travel with a monthly ticket. They were allowed to travel further.
So why were we not able to show the ticket?
