This would seem to imply that you can move 1 ton of stuff 500 miles on a gallon of fuel, or 500 tons of stuff 1 mile... Am I reading that right, 'cuz that seems awfully good milage.
Not true, because to move that one ton of freight, the engine must move the whole train as well, and the engine gets nowhere near 500 miles on a gallon of fuel, although trains are more economical than trucks, and will likely grow more so as oil prices continue to climb.
