The Santa Fe CF7 is an EMD F-unit railroad locomotive that has had its streamlined carbody removed and replaced with a custom-made, "general purpose" body in order to adapt the unit for switching duty. All of the conversions were performed by the Atchison, Topeka & Santa Fe Railway's Cleburne, Texas, workshops between February 1970 and 1978.[1][2] This was Santa Fe's most notable remanufacturing project, with 233 completed between 1970 - March 1978.[3] The program was initiated in response to a system-wide need for more than 200 additional four-axle diesel road switchers to meet projected motive power demands on branch lines and secondary main lines.

Santa Fe's aging fleet of F7 units were approaching retirement age in 1970. These units were remanufactured into switchers and named CF7. Santa Fe used them for a decade and sold many of them to short lines around the states. Many of those were still being used as of 2003.[4]
