On a CSX commercial, they said that one of their trains can tow 400 tons of freight 400 miles on one gallon of gas! Holy cow!
Now here's where I get mad and confused. why don't we just take the train engine, put wheels on it, and voila! we have a car that gets fantastic gas mileage! Or better yet, put wheels on the whole damn train and drive it around on the highway!
Seriously, why isn't somebody bolting that train engine to a suburban?
