The saying "Die Deutsche Bahn hat 4 Feinde - Frühling, Sommer, Herbst und Winter" (transl: "The German railway has 4 enemies - spring, summer, autumn and winter") is fitting once again.
Before the infrastructure was cut back, the motto was: "Alle reden vom Wetter - wir nicht" ("everyone is talking about the weather - we're not"): https://yewtu.be/watch?v=wvJAAzfK3Rk
