As JumpCrisscross asked the definition of on-time is important. Most Euro countries define "on time" as "within 5 minutes" with something like 90%+ of their train being on time.

SBB CFF FFS has similar numbers, except it defines "on time" as "within 3 minutes"[1] which is of course harder to achieve.
