The California, Arizona and Santa Fe Railway was a non-operating subsidiary (paper railroad) of Atchison, Topeka and Santa Fe Railway (ATSF). It was incorporated in 1911, and was merged into the ATSF in 1963.
California, Arizona and Santa Fe would ultimately be absorbed by Burlington Northern Santa Fe Railway.
It owned the ATSF lines between Phoenix—Ash Fork and Phoenix—Mojave. It leased/purchased the tracks built by the Southern Pacific Railroad across the Mojave Desert between Needles and Mojave in Southern California.
