We also have cross-country trains every 10 minutes and if you get to a station where you don't have a bike you can rent one from the train company. Or rent a car if you're a bit further away.
There's always room for improvement but right now they have a 90% on time record on an open rail system they share with competitors, foreign train services, and freight trains.
