The Grand Trunk Western Railroad (GTW) was a major freight railroad in the United States, operating primarily in the Midwest. Established in the late 19th century, it connected cities like Chicago, Detroit, and Toronto, facilitating trade and transportation across the region. The railroad was a subsidiary of the larger Grand Trunk Railway system, which originated in Canada. GTW played a significant role in the development of the American rail network, particularly in the transportation of goods such as coal, grain, and automobiles. It was known for its efficient service and extensive rail lines, contributing to the economic growth of the areas it served until its eventual merger into the Canadian National Railway in 1998.
