When they were demonstrating the FT, they compared an A-B-B-A with existing steam locos, and if they hadn't bested the steamer it was said they would simply have added another unit. So, if we don't restrict the discussion to single O-Gauge units (what defines a unit anyway?) then would an A-B-B-B-B-B....A best all locos? If its sold as an A-A pair, does that count as one loco? or two
Excellent point(s) Ken. True, what if a unit is really several sold as a unit?
I was leaning in the direction of a single locomotive. As in, one SD40-2 or perhaps a Big Boy. Just one locomotive against another to see exactly and precisely how much weight they can literally pull.
What prompted me to ask this question was, I have watched several videos at "Eric's Trains". Where he measures his locomotives during the review process.
