I think you can select any day, week, or month and the rail system in Germany will always be in chaos.
I didn't mean short-term bad timing, I mean it's bad that we're getting hit by increasing droughts in the same decade the train system hit its breaking point and needed fixing.
Post pandemic, it was decided that they had to fix it, at the same time that there's been a sustained surge in ridership. The operations to fix the rail network combined with decay, combined with higher ridership than ever before is what causes the chaos.
