The New Orleans, Jackson and Great Northern was a 206-mile (332 km) 5 ft (1,524 mm) gauge railway originally commissioned by the State of Illinois, with both Stephen Douglas and Abraham Lincoln being among its supporters in the 1851 Illinois Legislature. It connected Canton, Mississippi, with New Orleans and was completed just prior to the American Civil War, in which it served strategic interests, especially for the Confederacy. The New Orleans, Jackson and Great Northern was largely in ruins by the end of the War. From 1866 to 1870, when a hostile takeover induced a change of leadership, the president of the New Orleans, Jackson and Great Northern was P. G. T. Beauregard (1818-1893), former Confederate States Army general under whose command the first shots had been fired on Fort Sumter and who during the war helped design the Confederate battle flag.
Restored as part of the Mississippi Central Railroad (1852-1874), the properties originally belonging to the New Orleans, Jackson and Great Northern became, in 1878, organic with the Illinois Central Railroad, which billed itself as the "Main Line of Mid-America" and in 1967 became the Illinois Central Gulf Railroad.
