423 ton/miles per gallon is a load of crap. 350 maybe.

I haul freight in a truck at between 240-275 ton/miles per gallon.

Hauling freight by train in todays economy is not as much of an option as you might think.

Chicago to LA on a train takes about 7 days on a train, while it takes 3 on a slow truck, 24 hours on a team driven truck.

While the train may use a little less fuel for the main part of the haul, it still requires a truck to get it to the train and a truck to get it to it's destination. This has to be added on to the total cost.

I also doubt many people would want to eat produce that has been on a train for a week.

While on the surface it may look like trains would be a better idea, in reality it is more efficient for most of the freight on trucks to stay on trucks.

Large shipments from one location to one location are more efficient on trains, but smaller loads are not.
