This is a great thread. Thanks for starting it. On my own railroad, I pretty much always run a mix with the exception of a tank train. I really thought a set of approximately 10 Atlas 33k black tanker cars looked great together.
Back in the day when I was in public accounting, one of my clients was the Chicago & North Western railway. We did a revenue accounting project, and it was amazing to me how complex the billing was. There was an entire section of a floor of the old C&NW building that was the rating room where row after row of rating agents determined the bill. Rule 11, modified Rule 11, rating for switches, tariff rates, etc.
Thanks for bringing back these memories.
