Oh but the hubs stations in Switzerland do feature synchronized arrivals and departures on a 30 min schedule. It works so well you don't generally have to look up connections. Just be there at the sync time to board wherever.

This is a plan that shows the hubs and their sync time: https://upload.wikimedia.org/wikipedia/commons/thumb/a/a6/Kn...

You'll notice the ebb and flow of passengers if you sit at a hub for half an hour. Most people won't see the ebb because they're on their connecting train.
