To the extent that CNW laid much ballast on its South Dakota lines, such as Pierre-Rapid City (pre-DM&E), did the company use the same famous pink rock ballast as was used on its main lines in Illinois, Wisconsin, etc.?
I’m putting together a manifest freight representative of the latter 1960s on that route, and thought that I could add a couple of MW ballast hoppers with the appropriate load.
Thanks in advance for any help!
