Cameron is an unincorporated community in Warren County, Illinois, United States.

[3] Cameron is at the junction of the old Chicago, Burlington and Quincy and Santa Fe Railroads, both now owned by BNSF.

Cameron is the site of a 1996 connection track that was built between the former Burlington Northern line and the former Santa Fe's Chilicothe Subdivision, when the two merged to form the BNSF.

[4] This track allows both freight trains, along with Amtrak's Southwest Chief to use the Chicago and Mendota subdivisions between Chicago and Galesburg (already used by the California Zephyr), by way of Naperville, Princeton and Mendota.

Prior to 1996, the Southwest Chief, and its predecessor, the Santa Fe's famed Super Chief, traveled to Galesburg on the Chillicothe subdivision by way of Joliet, Streator, and Chillicothe.
