Tim and all:
The effect this can have on a modeled fleet is important. For example
in the 1948 Monon conductor's logs I was surprised at two predominant
home road car types: covered hoppers and side-dump gons. After
reading this thread, it occurs to me that these cars were likely in
captive service. According to the logs and despite their small
numbers, I should see more of them on my layout than Monon boxcars!
(in 1948 there were only 30 covered hoppers and 20 side dump cars vs.
1500 or so boxcars)
I wonder if this is the case on other roads; the boxcars being
swallowed up in the national pool and more specialized cars staying
close to home in captive service?
It happened all the time with open top hoppers - ergo, so few eastern hoppers going over Sherman Hill compared to eastern boxcars.
Meanwhile, I don't believe MONON's 20 side dump cars were even listed in the ORER's, and the 30 covered hoppers were on a tether to the cement plants on the MONON in southern Indiana (I assume).
