It's way worse now.
Last autumn I remember preparing for a work-related meeting in Leipzig on a zoom meeting. When talking about how to get there by train, one of the German participants started giving directions for how to use Deutsche Bahn and it honestly seemed more like the third world than supposedly modern and ultra-competent Germany...
"If you see a train going in the right direction just get on and then talk to the conductor" was one bit of advice I remember (along with the uselessness of current official posted schedules)..
I ended up not going (bit of a pity since I wanted to see Leipzig) but around the same time I was seeing other information indicating an almost total breakdown of scheduling..... what happened?
