 The route proposed in 1851 had the railroad's northern terminus in Cleveland, where it would connect with the Cleveland, Columbus and Cincinnati Railroad.The route then ran through Chagrin Falls, Garrettsville, Warren, Niles, Girard, Youngstown, Poland, and Petersburgh before terminating at Enon Valley, Pennsylvania.Company officials decided in 1852 to bypass Youngstown entirely, shifting the route south (along what is now Interstate 76 and Interstate 80) to reach Enon Valley.
