Oelwein to Dubuque, IA

The map is off, it follows an existing route rather than the old abandoned one...
Andrew is correct. The route shown between Dubuque and Dyersville is the Canadian National (formerly Illinois Central) route. The Chicago Great Western route between those cities is now the Heritage Trail http://www.dubuquecounty.org/LinkClick.aspx?fileticket=l_5MpQakit0%3d&tabid=193.
A revision for you...
The map appears to have been corrected since the two first posts, and it is now correct.
