There's an amazing talk about DB's punctuality from the 2019 Chaos Communication Congress: BahnMining, David Kriesel. Available in German, and interpreted to English: https://dkriesel.com/blog/2019/1229_video_und_folien_meines_....

My favorite anecdote from riding a German train in Switzerland was a journey from Interlaken (Switzerland) to Frankfurt in Germany. Now if you're not used to train schedules: Stops are quick, and trains are punctual. It's fairly common for stops to just be 2-3 minutes. Connections between trains are often around 5 minutes, sometimes shorter.

So, this Intercity Express departed Interlaken perfectly on schedule, made a bunch of scheduled stops in Spiez, Thun, Bern, and continued on to the border city of Basel. Everything running perfectly on schedule, the train arrived at the Swiss station in Basel, continued (on time) to the German train station that's still in the same city, just a few minutes farther. Having had 3-5 minute stops all the way from early morning to lunchtime, the train then sat in the German station for about 15 minutes, departed with only a minor delay, and just a few yards after exiting the station proceeded to stop, sit on the tracks for half an hour ("to catch up with the prevalent delay conditions on the German rail network"), before starting to move again.

Waiting in a comfy seat on a train with working AC isn't the worst of fates, and we made the final destination within half an hour of the scheduled time, so it all went well -- just funny to observe how different parts of this interconnected network had very different ideas of scheduling.
