If it was such a good idea, it would have taken hold when Trains were the masses way of travel. But it didn't and Henry Ford became Americas first Billionaire. And if it was such a good idea and the publics demand for it was so great PRIVATE BUSINESS would be competing with eachother in the market place. But private business is not competing with eachother because they know it is a loser. And I will say, that MOST of the people who support rail and want more people riding rail are leftists and socialists. And their main driving force behind it all is their uncontrollable urge to control our lives, tell us where to live, how to live, how to get around and what to do. It is about power and controlling the way people live.
The Depression killed many of these systems, and the government's highway-building program killed off the rest. Then a consortium involving GM and a number of others bought up the remainder and converted them to buses.
In cities today where diesel commuter rail has been recently instituted, it is a success.
You are absolutely right.
