I live in Jersey, and we have tons of them. And fortunately they are turning some into pedestrian paths, rails-to-trails style, but we have literal (albeit old) infrastructure for rail lines between places that are only accessible via rail by going to Newark, changing, and hopping on a different line. We're talking hours for a 30 mile ride.

I need me some eminent domain. There's some major hubs west of Newark that you can only drive between.

But yeah, seeing them turned into trails is at least better than nothing. But I want moooorrreee.
