I don't think this is actually true.

Looking at the top 20 metropolitan statistical areas in the US, you're already at nearly half the population of the US. And I know from the experience of having ridden commuter rail in most of those that most of them have commuter rail, i.e. passenger train service.

You've got to go pretty far down the list to find one without commuter rail or even a subway/light rail system (which I'm not counting as passenger train service).

If it isn't the majority, it's at least a normal experience for a huge swath of the population.
