As usual, DTTRR89ACE is spot on.
We have the finest railroad infrastructure on the planet. Passenger train travel fell from grace due to the lack of interest by the general public. And, this is not a class issue of any sort.
Post WWII America saw the beginnings of the interstate and federal high way projects, providing lots of work for returning GIs and the populace at large.
Once the roadway infrastructure was improved and the economic boom that followed provided the means for the every day Joe Schnook to buy his own personal transportation, people stayed away from rail travel in droves.
Gradually, as passenger trains more and more frequently ran in the red, one by one they began to be recognized for the dinosaurs they were becoming and carrier after carrier began removing them from service.
Consequently, as they were disappearing from the rail routes of America due to financial insolvency and public apathy, the Europeans, who had to rebuild all of their infrastructure after the devastation that was WWII, and in typical European fashion, were far sighted enough to know that the transportation of people was as equally important as the transportation of freight.
The availability of affordable air travel also made a deep dent in the customer base for the railroads that were still operating their own passenger schedules.
So now, due to economic restraints, emmissions levels, grid lock, steep insurance rates, sky rocketing fuel prices, etc., people are finally waking up and calling for the fire department now that the ship of mass transit has burned to the water line.
It is too late. Long distance train travel is quite impractical, if for no other reason than one will still need surface transportation from whatever depot they are deposited in to complete their journey, in most cases.
Even if we did have the system in place to support the travel, we'd still refuse to part with our cars and two story pick up trucks that can drive over anything except the two story pick up truck right in front of it.
So, forget mass transit in other than commute situations. Isn't going to happen here. Why? Where I live a gallon of regular costs $3.57. Guess what? There is not one car fewer on our streets.
So, hop in and fire that mother up! Be sure to goose the volume on the stereo too. In coming years we will have a medical problem in this country that will be as wide spread as the lack of decent mass transit. A significant portion of the population will be quite hard of hearing.
Bon voyage.
