For what it's worth, Being that they are made under the "Trainman" line of Atlas products, Being "prototypical" both road name specific and detail specific would be out of the question.
The whole Idea of the "Trainman" line it affordability/a little above basic details for the average/non rivet counting modeler. It's geared toward those who are not afraid to have some imagination in their train layouts, equipment and operation.
For those rivet counters. I suggest find a huge mega warehouse and build a huge mega "exact-scale" model right down to the ballast!!! That would be cool!!
These are model/toy trains, why not have some fun with some of these freedoms.
PS. Maybe Atlas can do a P72 and make them in "fictional" roads just for sales!!!!
