The Ann Arbor was a railroad stretching from Toledo, Ohio to Elberta, Michigan where it operated a rail car ferry until 1982. The ferry serviced the cities of Manitowoc, Wisconsin, Menominee, Michigan, and Manistique, Michigan. The Ann Arbor became a part of Conrail and then was later divided up between the Michigan Northern Railway and the Michigan Interstate Railway Company. The remaining portions of the line were absorbed into the state owned lines operated by the Tuscola and Saginaw Bay Railway.
