Well, after reading through the article it seems to have left one of my questions unanswered...
I was quite interested in the transition from the original horizontal dual motor drive to single drive to vertical drives and beyond. Especially the accompanying operational characteristics...the good, the bad, the ugly.
For instance, my 2343 set (still have it, of course!) is quite the 'growler' compared to later versions of the F's...and other diesels. While I never owned the various 'upgrades' (?) from those iconic originals, I have service many of them...neighborhood, family, word-of-mouth, etc., opportunities...not for hire. I noticed the change in speeds, power, sound (motor/gear sounds), among them. But I thought that 1990 article discussed the whys and whats of those drivetrain changes more in depth.
Ah, well, it's what I call a 'Tootle' moment for me...getting off track and picking daisies...having a flash recollection that I obsess over for no good reason except sudden curiosity...and a bad case of oldphartism.
Thanks for all the help and comments.
BTW, I wouldn't part with my 2343 ABA that Santa brought that long ago Christmas for a king's ransom...or an IRS settlement!
