During my last trip to Germany I made the mistake of traveling by train. My scheduled train got canceled and the next one would come in 1 hour.
I decided to wait and when the time came, no train showed up, the display said the train would arrive on platform 5, the announcement said it was platform 5, their app said platform 5 but nothing showed up.
About 10 minutes after the scheduled time I went to the ticket office to ask what happened, their answer was a “maybe it went through another platform”.
