one small problem though while i realize this is a "what if" question, $250 billion isnt exactly pocket change?
then again we could just add it to the deficit afterall its free money
seriously though i am really concerned that our country has so many important things that large amounts of money need to be spent on (existing infrastracture, education, social security, homeland security, etc.) combined with the huge deficit and enormous sums of money spent on the wars (who knows when they end), that would there ever be money left to spend on future new infrastructure like HSR? plus there is a real aversion to paying any taxes.
i really dont think the answer is to parallel the interstates with high speed passenger rail particularly in the interior west where there is low density and few large cities in close range to each other. i think this is pretty much what we want...
but of course theres some logical missing links that i would say are needed on this map such as connecting cleveland to buffalo, pittsburgh to cleveland, kansas city to tulsa, little rock to st. louis, houston to san antonio, houston to dallas, jacksonville to orlando and possibly louisville-nashville-atlanta.
its not that someone would necessarily travel from end to end, say kansas city to boston by HSR (though could) but that within that route it would serve many short trips of riders traveling to the next major metro area down the track (i.e. from chicago to cleveland). as much as i dislike flying one would still likely fly from new orleans to new york even if there is a continuous HSR line the entire way.
the only other real seperate HSR corridors i would think could be added to this map would be las vegas to los angeles (and the whole CA HSR system) and a route into Toronto.
ideally i see feeder lines (tying into HSR hubs) as important as the HSR lines themselves. the slower speed feeder lines going into smaller cities away from the main HSR corridors help provide full blanket coverage of a region. plus they also would cater to rural communities which is needed to provide transport to these areas and for poltical support whereas HSR alone entirely caters solely to large cities.
