Also of note is that you mention the Netherlands, which for routes like the one you mentioned still has the option for alternative routes with, in that particular case, at most a 30-60 minute delay from your original travel plan. At a larger scale / longer distances, that's no longer the case; if the track between Meppel and Zwolle has an issue, it'd be better comparable; that basically severs the north from the south. Compare NL with France, too: http://www.fairriqh.nl/stations/Spoorkaart/Spoorkaart%20Nede..., http://www.bonjourlafrance.com/france-trains/images/france-t..., NL looks more like a subway system.
