The german trains, even at their worst, are so much better than anything in the US. Complaining can also be a sport in Germany. Take a ride on Njtransit or the NYC subway to appreciate the difference. Or try to get anywhere in New Jersey without a car. In many parts of Germany, you can get almost anywhere conveniently with only public transportation.
what’s going on in New York is irrelevant. The trains in Germany are largely bad. Bad enough that I don’t use them unless I have to. Once they’re at that stage it doesn’t matter how much worse they get for me, I still won’t use them.
