As if! Deutsche Bahn is late all the time, some WWII bomb is found and the track goes through the evacuation zone, someone blocks the trains door from closing because he wants to finish smoking his cigarette, train stops on a turnout track because of course freight trains are more important, people on the rails, fallen tree after a storm, etc etc. Of course compared to other countries our trains are probably still pretty punctual, but it's still annoying when you are stuck at the station for an hour when your whole trip only takes 45 minutes otherwise.
Especially the WWII bomb thing is annoying, because they tend to find one every few weeks when there's construction near the tracks.
