The Land O'Corn was a streamlined passenger train operated by the Illinois Central Railroad between Chicago, Illinois, and Waterloo, Iowa, from 1941 until 1967. Its inception was due in no small part to John W. Rath of Ackley, IA and part owner of the Rath Packing Co. of Waterloo, Iowa as well as a member of the Illinois Central's board of directors. It featured a wide range of equipment over its existence, including self-propelled Motorailers and steam locomotives, before finally adopting conventional diesel locomotives and lightweight cars. The Illinois Central discontinued the Land O'Corn in 1967; Amtrak later operated the Black Hawk over part of its route.
