CN Markham Yard is a major railroad facility located in the south Chicago suburbs near Homewood, Harvey, Hazel Crest, and Markham, Illinois.
The yard was originally developed by the Illinois Central Railroad and remains one of the most important railroad properties associated with Canadian National’s operations in the United States.
In addition to classification and yard functions, the facility is closely connected to Woodcrest Shop, a major mechanical complex that Canadian National identifies as a hub for its U.S. mechanical operations.
The development of Markham Yard reflected Illinois Central’s effort to modernize freight operations in the Chicago region during the early twentieth century.
Construction was authorized in 1917, delayed by World War I, and ultimately completed in 1926. The yard was named after Illinois Central president Charles H. Markham and became a central component of the railroad’s Chicago-area operations.
Following Canadian National’s acquisition of Illinois Central in 1998, Markham Yard became part of CN’s North American freight network.
Today, the facility continues to support classification activity, locomotive operations, mechanical services, railcar handling, maintenance work, and other railroad functions tied to one of the busiest freight corridors in North America.
