Hi Henry:
Looks like your list is pretty comprehensive.
One minor item would be naming convention, the lumber would be coming in/loaded onto flats (F) or bulkheads (FB) and not log cars. There is a significant difference between the cars.
Noticed the question mark by the "Molasses" spot. I can fill in a detail there: This industry is modeled after one locally that produces a supplemented "sweet feed" for cattle. It has the unimaginative name "Animal Feed Suppliment Company". The molasses is used as an additive to be cooked into the feed bran. (The place smells great on a cold, snappy morning... like hot molasses waitin' to be spread onto a biscuit!) The finished product is shipped in metal half-drums. The prototype AFS no longer uses rail service, but I decided to model a version that still uses it. Below you will see a picture of the prototype.
Also, as I recall, inbound additives for feed production could be such things as corn syrup, fish oil, protein oil, and such. That later two being quite "aromatic".
If you have specific questions about specific industries, don't hesitate to ask.
