There was a thread some years ago about "standard weight" carloads (for lack
of the correct term),. Like grain loads?

For modeling purposes. I weigh all loads that come out of my packinghouse.
In reality would by-products be weighed. Or would an agreement be made
between the customer and railroad for a standard weight? For say, hides or
tankage???

Thanks for any help : ))
