Somewhere I heard that a 40" wheel contacts the rail for an area the same as the area of a nickel. "Nickel" seems to be a very important RR and model RR word! The whole subject of locomotives pulling feels like I'm watching the play "Charlie Victor Romeo"! There are a bazillion obvious questions not being asked...
Like: are the motors identical or do they have identical out puts; is the weight evenly distributed; are gear boxes and gear ratios optimum for the motor's out put or how many gear boxes are there and what is the free rolling resistance of the model???? Personally I don't think it makes much difference. If you need more power to get up the hill, prototypical operation would call it something like a "pusher district". Enjoy... I intend to spend the balance of the day railfanning and hopefully retaining precious decoder smoke at DPV.
