I guess a joke from the train driver like this article says.

Took this exact train last year. Was kinda surprised to see this before we got into Frankfurt Station. I think train drivers put in in individualized messages at the end their shift. Once encountered one that said “train sleeps” and “Endlich Feierabend”. I made a habit of taking photos of them
