Grand Trunk Western Railroad
American railroad

The Grand Trunk Western Railroad Company (reporting mark GTW) was an American subsidiary of the Grand Trunk Railway, later of the Canadian National Railway (reporting mark CN) 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 Michigan Division. Its primary mainline between Chicago 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 haulier of parts and automobiles from manufacturing plants.

Mainline
Grand Trunk Western began as a route for the Grand Trunk Railway (GTR) to link its line to Chicago through lower Michigan. GTR's objective was to have a mainline from shipping ports in Portland, Maine, to rail connections in Chicago through the southern part of the Province of Canada that would serve Toronto and Montreal.
In 1859 the Grand Trunk completed its route to Sarnia, Canada West, and began a ferry service across the St. Clair River to Port Huron. GTR leased the Chicago, Detroit and Canada Grand Trunk Junction Railroad to reach Detroit and from there then ran over the Michigan Central Railroad's line from Detroit into Chicago.
