The delays in Germany can also be felt here in Linz/Austria.

For years the train from Linz to Vienna was always punctual.

However, recently (Last ~9 Months or so) all trains are super later. The reason is, all of them go through Germany (Innsbruck (via German) -> Salzburg -> Linz ->Vienna), and given everything is delayed in Germany it also delays Austrian trains.
