almightybmw,
I fully agree that a train is still more efficient at transporting huge loads over long distances. what I don't like is the little blurb they put on NPR saying that the train can move 1 ton 400 miles on a single tank of fuel, when in reality no trains ever carry only 1 ton of anything. The cars weigh more than that empty. And yes, I'm arguing semantics here, I'm fully aware of that.

BTW, I was too lazy to compute the efficiency of an auto in moving 1 ton, thanks for doing that it's pretty eye opening.
