I mean that Switzerland has a local and regional rail system that is damn near perfectly sized, scaled, and engineered for its geography and citizenry, which also integrates pretty well with the rail systems of all of its neighbors.

They could have made faster trains, but with the way they wanted to run them, it made more sense to design the rolling stock to have good top speed, but excellent acceleration, thus improving the average speed more meaningfully than a higher top speed would. The rail network is fairly pervasive - you can from and to just about anywhere in Switzerland using trains, with perhaps a bit of bus travel tacked onto either end.
