What companies do you have in mind? I'm not aware of any organization that spends heavily on lobbyists and would stand to profit from more trains; train manufacturing is generally a small part of big conglomerates, like Siemens and GE. (This is the product of long, frustrated research on exactly that point.) If it's self-driving cars you're thinking of instead of trains (and self-driving cars are a ludicrous solution, with all the drawbacks and none of the advantages of both cars and trains), they're a fad, and they sort of market themselves. When they fail to deliver in 5-10 years, we'll be free of that crap. The majority of this sentiment is the millenial preference for living in cities like traditional civilized peoples, instead of out in plastic suburbs with no commerce except retail chains and no social activities except TV, Evangelical megachurches, and sportsball. Kunstler's Geography of Nowhere might be worth reading on this subject.
