Switzerland has villages with only hundreds of people that regularly receive train service. There are states with similar GDP, size and density as Switzerland that do not have any train service.

Sprawling suburbs are a giant scam - the cost of providing urban amenities (power, internet, sewage) to these neighborhoods is much higher than it appears. The lines of pipes and power lines in sprawling burbs cost wayyyy more than it would to maintain a transit oriented development full of townhomes and condos.
