Don't know if any interest is this kind of stuff, but here's a local's report for the Saginaw Divn from February, 1975. This was issued daily by the chief dispatcher showing locals/road switchers and all cars handled (loads-empties-tonnage). This was only locals -- not manifest or unit trains. We also had locals at Lincoln, Wayne and Monroe, but even though we dispatched, everything south of Wixom was part of the Detroit Divn. As info, 22/23 were "through" locals on the Elmdale Sub (in addition to manifests 58/59 on that line).
