Be aware, that the SBB in Switzerland measures delays differently than other Countries. They don't look at train departure times, but passenger arrival times. E.g in Germany a train is considered delayed if its more than 5 minutes and 59 seconds late, whereas in Switzerland the percentage refers to passengers that arrive within 3 minutes and still have all the connecting trains available. https://company.sbb.ch/content/news/de/2015/1/1201-1.html https://company.sbb.ch/content/news/de/2015/1/1201-1.html
