I've witnessed many coal trains out West "grunting" up grades in in run8. What a beautiful sound! Remember, I said STARTING trains. Heck, most of the time was spent in the 8th notch. I still have a license plate somewhere in the garage that says "THROTTLE8"! (lol, we all had our images to uphold!)
Peteski and Davefoxx, you guys are right on the money!
