ok, so all info is from here: http://en.wikipedia.org/wiki/Energy_in_the_United_States#Current_consumption
broken down by sector, we see transportation takes up 28% of total consumption of oil. Air travel takes up 12% of this, or 3.36% total.
space heating in residential homes is 6.72% of total. Basically, you would be TWICE as effective by attempting to change the way people use their own electricity for heat than you would by changing air travel.
Broken down by supply/demand, we see over 40% of all oil consumption goes to electricity.
EDIT: i will leave this up for all to see, my post is entirely BS, I totally just realized it... please ignore this energy break down, I messed it up, and really don't want to do the math necessary to fix it... look, everyone can see how terrible my basic reading skills are

In the other hand though, we know its not going to be like that forever. So why continue to use a system that will eventually fail?
1) the technologies you are talking about are in their infant stages, are inefficent and are clearly going to become much more affordable and effective in 10-20 years. Even if we suppose that the rail system you propose is a) possible and b) practical, there is no reason to do it now, rather invest into technology research for 15 years, and then use the mature and more effective technology to replace air travel
2) I can't imagine rail travel being anywhere near as effective as air travel. ware and tare of the tracks being the biggest obstacle I see. the most likely, and probably most desireable future, is one where air travel has been made green. (I am also just going to a priori assume air travel is safer than rail...)

The machines that are ran to produce and harvest our food source is all done using fossil fuels. Well eventually were going to have to turn to the use of another energy to wield our machines into action.
you are thinking of the wrong machines though. Its not your car, its your computer, refrigerator, air-conditioning, lights... etc. While transportation, as a whole, does take up a significant amount of oil, it is not the majority or even the largest sector/demand.

Energy as of right now is the main reason we are what we are today. With out the discovery of oil we would have never reached the growth and population we have today as I'm sure you know.
counter-factual history
oil companies have been at least somewhat detrimental to the progress of human technology. There is no way to know what might have been if there were no oil companies to kill public transportation and electric cars (if we are only looking at transportation, of course. Oil companies are also pretty anti-any-green-solution).
