History
The Illinois Central Railroad was chartered by the Illinois General Assembly on February 10, 1851, though the company's origins trace back to an earlier incorporation in 1836 and a prolonged effort to secure federal support for its construction. That support finally arrived in 1850, when President Millard Fillmore signed legislation authorizing a federal land grant to finance the project, making the Illinois Central the first land-grant railroad in the United States and establishing a financing model that numerous subsequent long-distance railroads would follow. Upon its completion in 1856, the IC was reportedly the longest railroad in the world, stretching from Cairo, Illinois, at the confluence of the Ohio and Mississippi rivers, northward to Galena in the state's northwest corner, with a branch extending to the rapidly growing city of Chicago. Among the prominent figures associated with the railroad in its early years were Senator Stephen A. Douglas, who held land near the Chicago terminal, and Abraham Lincoln, who served as a lawyer on the railroad's behalf before his political career brought him to the presidency.
Throughout the second half of the nineteenth century and into the twentieth, the Illinois Central expanded aggressively, acquiring and constructing lines that transformed it into a true north-south trunk railroad. By the 1870s and 1880s, the IC had extended its reach deep into the South, with routes penetrating Mississippi and reaching New Orleans, Louisiana, and east toward Louisville, Kentucky. Northern extensions pushed into Iowa and eventually connected Chicago westward to Sioux City, Iowa, with further branches reaching Sioux Falls, South Dakota, and Omaha, Nebraska. This sprawling network, which the railroad promoted under the slogan the Main Line of Mid-America, became an important artery for agricultural freight and passenger traffic alike, and during the era of the Great Migration in the 1920s it served as a primary route for African Americans traveling northward from the Deep South to cities like Chicago. The IC's most celebrated passenger train was the Panama Limited, an all-Pullman service operating between Chicago and New Orleans that embodied the railroad's identity as a premier passenger carrier along its flagship corridor.
On August 10, 1972, the Illinois Central merged with the Gulf, Mobile and Ohio Railroad to form the Illinois Central Gulf Railroad, operating under the reporting mark ICG. The combined railroad was substantially larger but also burdened with considerable redundancy in its route structure. During the 1980s the ICG undertook a dramatic downsizing, spinning off large portions of its east-west lines and many duplicate north-south segments, including much of the former Gulf, Mobile and Ohio network. These properties were absorbed by a variety of carriers, including newly created railroads such as the Paducah and Louisville Railway, the Chicago Central and Pacific Railroad, and MidSouth Rail Corporation. On February 29, 1988, after its parent company IC Industries separated its remaining rail operations and reorganized itself as Whitman Corporation, the railroad shed the Gulf designation and once again became the Illinois Central Railroad.
The reconstituted Illinois Central operated as a lean, focused railroad centered on its original north-south mainline between Chicago and the Gulf Coast, and it attracted considerable attention in the industry for its efficient operating practices. That reputation made it an attractive acquisition target, and on February 11, 1998, Canadian National Railway purchased the IC for approximately 2.4 billion dollars in cash and shares. Integration of IC operations into CN began on July 1, 1999, effectively ending the railroad's independent existence after nearly 148 years of operation. The Illinois Central's mainline became a critical piece of CN's transcontinental network, linking the Canadian carrier's existing routes to the Gulf of Mexico and giving it a through corridor from Canada to New Orleans. The Illinois Central Railroad continues to exist as a non-operating subsidiary of Canadian National, its reporting mark IC surviving as a reminder of one of the most historically significant railroads in American history.
