We need help in creating that route! It is a modified version of Garber's Ohio Rail and will feature UP trackage to Janesville and Kenosha, BNSF trackage to Rockford, CSX trackage to Benton Harbor and NS trackage to Niles. States included are Illinois, Wisconsin, Indiana and Michigan. Ohio Rail features two railroads centering around an industrial city named Marietta. Well, the route has four railroads centering around Chicago, a renamed Marietta. Here's a map. And the stray tracks in all cities are there because they are railfan spots.
It has high speed Amtrak passenger service, Metra commuter service and an unending number of hotshot, wayfreights, and heavy manifests of UP, BNSF, NS and CSX. A good mix for all!
