Ah ha ha ha ha ha. USA tried. It failed so hilariously bad that they're now actively protesting against new rail. There's this crazy thing, rail needs to be near places people actually want to go. But those places have NIMBY voters, so populated areas won't get rail. Instead they go to empty parking garages near malls. And then shocker, no one rides. It's so bad in Denver that they're using them as a case study to prevent expansion in Utah.
