William,
?
I can't comment directly on C&O practices, but the Missouri Pacific Circular #1 shows a diagram (dated 1972, but still relevant) that outlines the progression of dirtiness and the cleaning process required between different types of loads for covered hoppers. I find it interesting that a car that carried cement has to be sandblasted to haul any other product. Silica sand and alumina being interchangeable with rice, soy beans, and wheat is interesting also.?

Additional info from the STMFCL
1958 cuft 70-ton covered hopper
the Prototype Cyclopedia on these cars indicates they also carried soda ash, potash, phosphates, borax, sand, quartz/silica (for glass making), alumina, sodium bicarbonate and zinc oxide.?

As the logos on SHS cars would indicate==Trona, Borax.? My understanding also indicates that South Dakota state owned cement traveled East in C&NW hopper cars rather than farmer's corn.

I went to Trona, CA 20 years ago on business. What an inhospitable place. Dried up borax lake. Never saw so many literally burnt out homes. Outright depressing. All but gone today I believe.
 

That's a very interesting document from the MoPac in 1972. I'm guessing something similar was on record at most railroads since the mid-1950s.

I'm glad I wasn't employed by a shipper in those years.

It's no wonder that the railroads lost high-value commodities to trucks throughout the post-War era.

Ron,
Trina is interesting to view in Google Maps, Sat mode. The north end of town has a reverse loop with a 4 track, unhindered, staging yard. Pretty cool.

Thanks for the chart. I like it.
?
When I was distributing covered hoppers at Santa Fe in the first half of the 1990s, we did not have such a chart, but some of it was programmed into the computer. You got to know what you could do and what you couldn't.
?
One commodity that the referenced chart did not cover was cullet. Once a covered hopper was loaded with cullet that was all that the car could ever carry. One did not want to be responsible for a perfectly good car to get in cullet service. Our assigned cullet cars generally were the first series of three bay covered hoppers that Santa Fe owned. They were pretty much rust buckets and had lower cubic capacity than the later three bay cars.
