[2] However, as of 2021, declines in network coal shipments have dropped Kansas City to second busiest and second by annual tonnage behind Chicago.

[3] In 1875, the Atchison, Topeka and Santa Fe Railway (AT&SF) began constructing the first railroad facilities in Argentine with warehouses and workshops, which were expanded into a passenger, freight and classification yard with over 40 km of track by 1890.

[4] As at many other freight yards in the Midwest, the AT&SF also built a grain elevator with a large silo complex.

The increasing mechanization of agriculture greatly increased the volume of grain handled in the 1920s,[5] forcing the expansion of the complex's capacity from the original 1 million bushels to over 10 million bushels (about 350,000 m³), creating the second largest facility in the United States; it was operated by the lessee Davis-Noland-Merrill Grain Company.

[4] In 1995, the AT&SF merged with the Burlington Northern Railroad (BN) to form the Burlington Northern Santa Fe Railway (BNSF Railway), which demolished the silo complex in 1996 and completely rebuilt and modernized the rail yard by 1997.
