The Illinois Central Railroad (reporting mark IC), was known as the “Main Line of Mid-America” and was a Class I railroad in the central U.S. that extended over 6,500 miles across thirteen states that included Iowa, South Dakota, Minnesota, Wisconsin, Illinois, Indiana, Kentucky, Missouri, Tennessee, Arkansas, Louisiana, Mississippi, and Alabama. The Illinois Central reached into all three ICC geographic districts; Eastern, Southern, and Western. The IC’s primary routes connected Chicago, Illinois with New Orleans, Louisiana (921 miles) and Mobile, Alabama. Another line connected Chicago with Sioux City, Iowa. There was an important branch to Omaha, Nebraska west of Fort Dodge, Iowa and another branch reaching Sioux Falls, South Dakota starting from Cherokee, Iowa. The Sioux Fall branch has since been entirely abandoned. In 1998, the Canadian National Railway (CN) gained control of the Illinois Central, and it is now a subsidiary and part of the CN Southern Region.
