Hmmm.... were you watching me counting my fleet of locomotive a couple of days ago???? Seriously... I was up at 2:00 AM looking at the quantity of locomotives for my NON-main road fleet. I can give you an idea of the Western Pacific ~5%, Northern Pacific ~6%, Southern Pacific ~17% & ATSF ~17%... but... that's as far as I got. I can only imagine that I have slightly more than 20% of the Rio Grande... which is my main road name. I have several other western road names too... which likely makes up the other ~30%. Probably a total of 5% of eastern road names and undecs make-up the rest.
