Obviously it wouldn't be fair to do a straight comparison of a 4500 HP engine against a 3800 HP engine, but it would be very interesting to see how much fuel each engine uses per unit of horsepower created. If that makes sense. I'm operating sans caffeine this morning.
Another option would be to compare the two locomotives (ES44AC and PH37ACi) in terms of tractive effort in relation to fuel consumption.
