If you look at a map of the Chicago & Eastern Illinois, it forked south of Woodland, IL into branches to Danville-Evansville and to St. Louis. The St. Louis branch then had another branch leave it southwest of Findlay, IL, to head south into Illinois' coal country. It is this southern branch that crosses the Kaskaskia River valley.
