Its those diesel trains that can go 400 miles on a gallon of gas.
******************************************************
Their advertisements actually state 1 ton of payload 400 miles on 1 gallon of fuel.. not quite the same..
Still, that's not bad. But I never got that impression from the commercials. Maybe that was the idea. I shall from this day forward look for derivations from the truth in each ad, except Bud-lite 'cause they're always honest, honest.
