Shawn,

My question to you is, what is this information for, modeling? Are you writing and article? What?

The Auto Industry was and has been a very demanding business for the Railroads. Timing is and was everything. Remember the rates during OUR era were fixed, in regulation. Never reading the Walthers book I would imgine that it is not as bias as one might think. The infrastructure of the industry was much the same for all the producers during this period it was just the loading techniques and equipment demands that were different as was the destinations and origins.
