Responding to Tim Gilbert:Mont,
We are in agreement regarding type of cars. But what is the rhyme and reason behind the variety of car owners? Bill's data provides insight into some of the rhyme or reason of behind this variety of owners of boxcars and tank cars.
Each boxcar could carry a variety of commodities while tank cars were restricted to only a few, if not just one commodity. Hence, empty boxcars could be easily reloaded while empty tank cars generally had to return to their original point of loading before they could be reloaded. This difference is reflected in boxcars' loaded car miles being about 76% of total car miles in 1948-49 vs. the tank cars' loaded car mile percentage being only 50%.
Tank Cars were generally leased from private owners or owned by industries; thus, they were not free rollers - indeed, they earned mileage paid by the carrier to the owner instead of the per diem paid to the boxcar owner.
Because boxcars were free rollers because they were capable of showing up on any road different from the owner with a load originated on still another road- in Bill's latest sheet, CB&Q #26046 was loaded on the NKP with bean meal for AK Zinn, and routed NKP-Michigan City-NYC(MC)-Battle Creek. Another example was NP #26144 which was loaded with bean mail for the EW Bailey Co. in Montpelier VT and routed NKP-Toledo-DTSL-Detroit-GTW-Port Huron-CN-St. Albans VT-CV-Montpelier. (Incidentally, this would have been a "legal" routing of a Canadian car because of the transit through Ontario and Quebec.)
The distribution of ownership of Boxcars from the Swift Processing Plant resembles somewhat the distribution percentages of boxcar owners in wheel reports that I have parsed from the SOU's Washington Division in the Fall of 1946 and the UP's Wyoming Division in the Fall of 1947. They do not correlate perfectly with each other. But for modelers not having the advantage of a wheel report, or cars pulled from Frankfort, a good starting point in selecting what the owners of foreign boxcars should be on a layout would be based on the percentage of boxcars a specific railroad owned of the national fleet.
I guess that you will not be modeling CIL #1 at least between June 1947 and June 1948 because it was used to originate only one load, and terminate none on the MONON. Seriously though, gauging how many and what cars were loaded with merchandise or used team tracks is the bane of a prototypical modeler. What bails you in terms of ownership of boxcars is the starting point of percentage of boxcars owned by a road of the national boxcar fleet.
I would think that Bill's data has helped you with boxcars and tank cars carrying bean oil; the data has not shown the distribution of owners among hoppers, gons, reefers or tank cars carrying different commodities than bean meal.
