Here in the Netherlands there's actually fewer routes than a 100 years ago (country was full of local 'intertown' trams then). Housing stock has expanded a few times over since the war, but rail routes (light of heavy) stayed put. It's ridiculous to build a 5000 home neighborhood and not plunk down some steel bars! Or at least reserve the space. Meanwhile, bus services are down YoY in frequency, reach. They now basically only serve as a last resort for those that really have no other options and thus can be forced to deal with incredible transit durations.

Even cycling, which in denser cities can absorb some of the commuter traffic, is not encouraged as part of mixed transport. Tax law is such that one modality can be compensated.

The Netherlands has none of the geology to deal with that Switzerland has, so I don't know what excuse there is. All energy went into cycling I suppose. Not bad, but it's about the network, and never about the one modality.
