In the 1980s, the Atchison, Topeka and Santa Fe Railway (SF) and Southern Pacific Transportation Company (SP) attempted a merger. It began with the merger of holding companies Santa Fe Industries and Southern Pacific Company on December 23, 1983 to form the Santa Fe Southern Pacific Corporation (SFSP), which held the SP shares in a voting trust. After the Interstate Commerce Commission denied the merger, SFSP sold the SP to Rio Grande Industries on October 13, 1988, and was renamed Santa Fe Pacific Corporation on April 25, 1989.
The holding company controlled all the rail and non-rail assets of the former Santa Fe Industries and Southern Pacific Company, and it was intended that the two railroads would be merged. They were confident enough that this would be approved that they began repainting locomotives into a new unified paint scheme, including the letters SP or SF and an adjacent empty space for the other two (as SPSF, the reverse order of the holding company).
