Grand Trunk Western Railroad

The Grand Trunk Western Railroad Company is an important American subsidiary of the Canadian National Railway  operating in Michigan, Illinois, Indiana and Ohio. Since a corporate restructuring in 1971 the railroad has been under CN's subsidiary holding company the Grand Trunk Corporation. Grand Trunk Western's routes are part of CN's Midwest Division. Its primary mainline between Chicago, Illinois, and Port Huron, Michigan, serves as a connection between railroad interchanges in Chicago and rail lines in eastern Canada and the Northeastern United States. The railroad's extensive trackage in Detroit and across southern Michigan has made it an essential link for the automotive industry as a hauler of parts and automobiles from manufacturing plants.
