Americans passed on passenger rail due to more modern inventions like the automobile. Being able to “drive yourself” was the ultimate freedom. Trucking (and the interstate highway system) post WWII made it so trucks can get to every major city without hassle. This was because of the rail system being clogged up and some railroads failing (merger). People are starting to come back around to passenger rail service as more younger adults forgo the traditional driving right of passage. Sun rail in Florida for example. Metro subways. Etc. For longer distances, we have Frontier Airlines which is like the Greyhound Bus of the sky. Tickets are dirt cheap and you get what you pay for. Americans also designed their cities to be driven and not walked so we kinda went all in on “Ford” early.
