For example, in 1950, tons of coal received from other roads:
D&RGW: 2200k tons UP: 3300k tons
These two are rather interesting. Perhaps D&RGW figures are due to the Utah Coal Route, but UP's is intriguing.
SP: 300k tons MP: 1100k tons NKP: 10900k tons (suggests why the NKP was bought by the NW, doesn't it?) NW: 4900k tons CBQ: 2400k tons
I certainly can understand the Q, given the diversity in Southern Illinois.
Yeah, mostly GS gons, not hoppers, but the point here is about coal
routings
and most of the data I have is western, but it does address the point. Anyway, coal carloads averaged a bit more than 50 tons/car if one wants to calculate carloadings. By this measure, the puny tonnage on the SP still amounted to ~6000 cars in the year.
And the large tonnage received by the N&W is a curiosity....
