Not really a good example, Swiss rails are supremely expensive to state and travellers too. Most countries wouldn't be able to afford such density to have good coverage. They definitely don't run very precisely in many places due to many factors, as a local I can attest to that with many late arrivals to work in the past.

These days they run almost empty at huge losses. You still need to haul 300 tonne of steel through whole country, even if there are 5 passengers.

Maybe its the best implementation of the train network for civil travel, but still needs to be heavily complemented by network of buses to all small places.

And that grandma drive to the door would still have to use a taxi every single time.
