Re: Top 20 North American Freight Car Fleets, January 1949
Mike, essentially what I meant to say (but only implied) is that iftoggle quoted messageShow quoted text
you are modeling a coal road like the C&O in an area full of coal mines,
then the vast majority of the coal cars seen will be C&O. But if you model
C&O in eastern VA or in Ohio, there may be many more foreign hoppers.
The point was that hopper/gondola population mixtures are far more
dependent on local factors than are box car/reefer mixtures, for most
mainline modeling. I think that is sufficiently vague and general. :-)
Suppose one sits down and decides that 50% of the fleet needs to be
box cars. Then one says that 20% of that number needs to be home road
and 10% is direct connections.
So now apply the population percentages to the 35% of your total freight
car fleet (.70 x .50) that will be "random" box cars. Note the randomness
does NOT exclude home road or direct connections. Why? Simple. If your
home road owned 90% of all the box cars that existed, then you should
expect more than 90% of all the box cars on your layout to be home road.
I'll grant you that large numbers of eastern RR hoppers might not have
