@nilz @collectifission I was told this earlier in the evening by Germans. Apparently Deutsche Bahn are awful for time keeping.
Same conversation had a Dutch chap telling how a Canadian train he was on (one of a fleet which the Dutch have bought) stopped on track, lights went off for a few minutes, came back on and the train pulled off again. He's a government person who deals with transport. Apparently there was a software issue and the checklist said to restart it which knocked everything out.
