Larry, was there any through freight or passenger train between Marion and Dayton (possibly with Cincinnati as a final destination). My question may seem stupid, but I looked at many employee timetable for that area ranging from the 1930s up to the 60s and no trains are ever mentioned on the schedule for Dayton Branch. I find it weird... really weird.

Here's one of the ETT:

Public timetables are also mute about that.
