Any ideas on realistic scenario design?

I'm working on a (hopefully realistic, or at least semi-realistic) scenario for the Granger Heartland route that is supposed to serve as an "introduction" of sorts to the route (explaining what industries the route serves, as well as some of the history of the route).
My current idea is a point-to-point freight (specifically an Oklahoma City-bound autorack train) that just cruises through the route without any interruptions, while the conductor occasionally explains some information about the area the train is passing through.
I would like to hear you guys' thought on what you think needs to be added or changed.
