IC serves coalmines in Illinois by means of branches leaving the mainline to the east just south of DuQuoin. Coal trains from (say) the Powder River Basin in Wyoming to power plants in the area also traverse portions of the IC mainline. For example, UP coal trains from Powder River to Liss, IL, runs along the IC main south of DuQuoin, with empties in reverse. Powder River coal is also carried between DuQuoin and a power plant at Moss Point, MS.

NS has trackage rights on part of the Gilman District for automotive trains to its own line at Gibson City. There seem to be no dedicated automotive trains on the IC mainline.
Numerous trains run along the IC main to the turnoff for Decatur where ADM and Staley have large plants. These include trains from Glenwood Yard in Chicago plus the Champaign and Cairo to Decatur locals, which are mainly grain cars. The Cairo trains carry grain between the mills at Decatur and barge transshipment terminals at Mound City on the Ohio River. Grain trains also run between Peoria, IL, and Remy, LA for export shipments, and grain is carried locally between Memphis and Marks, MS where there is a grain processor.
In 1997, one third of IC’s total revenue came from the “Chemical Coast” along the lower Mississippi River in Louisiana. These plants are served from Geismar Yard, and by the freights between Geismar and Memphis.
