Flyover county was definitely included in my initial response about at grade crossings, but wasn't specific to passenger rail, and why wouldn't it hypothetically be included? There already is rail everywhere, that's why I suggested it's a bit fanciful, it's just mostly freight. Doesn't necessarily need to be bullet trains, but given how bad North America seems to be at building any major rail projects in the modern era, I don't really have high hopes for advancement in this area, just dreams.

I do tend to prefer rail whenever viable, and the cascades route is already halfway decent, just not competitive on any front except ease of access with flying.
