Hello,
Our journey in the app and on our pass was from Amsterdam Centraal to Mainz Hbf. Our first train showed it taking us to Frankfurt where we'd have to transfer for the last leg of our journey. However, we got to Koln Hbf and were told it was the end of the line. There was a group behind us that were also under the impression that we could stay on. They asked the worker and he said we have to get off, we have to listen to the announcements, and yelled at all of us for missing the 3 announcements telling us to get off.
He said to go to platform 10. We rushed over there but there was no departing train that matched anything in our app. We looked for trains heading to Frankfurt or Mainz and there was only one and it was not on platform 10. It had already departed by the time we found it. We looked at 3 different information boards and a separate app for train travel and we could not find the original information we had in the rail planner. We ended up getting tickets to a train an hour later, adding 3 hours total to our journey time. Would our tickets have worked for the one train going to Frankfurt? Did the app not update or did we just do something wrong?
