Actually, every American town founded before 1950 had a train line going through it. Aside from people living on homesteads, and maybe some small antebellum towns, everybody lived in close distance to a train station before they were shut down and torn up.

Worth noting that this map is for passenger rail only. The cargo rail network is much bigger. Basically, this map shows whereever Amtrak runs, where as before the introduction of massively subsidized interstates in the US in 1956, every cargo rail company also ran profitable passenger rail traffic on a massive network that became today's cargo lines.

The cargo companies dumped their traffic onto the federal government in the 70s and have also ran massive cost cutting programs since, tearing up hundreds of thousands of miles of rail.

Who Framed Roger Rabbit was a documentary. Not the toon town stuff. The part about the judge buying the trolley so he could shut it down to build a highway. We used to have a better rail system than anywhere else. Then the car and oil companies bought the tracks and paved over them in the 1920s to 1950s
