The Illinois Central Railroad (ICRR) operated approximately 600 miles of mainline track throughout the Commonwealth of Kentucky, stretching from the Mississippi River to the central part of the state. In addition to Louisville, the state's largest city, the ICRR also served dozens of small towns. Kentucky's economy was built around coal mining and farming, and the ICRR played a major role in both industries. ICRR's coal trains served as a conveyor for Kentucky coal moving to Midwest factories, and the road hauled a wide variety of agricultural products, including tobacco, grain, and fresh fruit. No mention of the ICRR would be complete without discussing the fleet of fast passenger trains that whisked Kentucky residents to and from distant cities. To maintain the locomotives that hauled all these trains the ICRR operated one of the nation's largest locomotive repair shops in Paducah.
