The San Diego and Arizona Railway (reporting mark SDA) was a short line U.S. railroad founded by entrepreneur John D. Spreckels, and dubbed “The Impossible Railroad” by engineers of its day due to the immense logistical challenges involved. Established in part to provide San Diego with a direct transcontinental rail link to the east by connecting with the Southern Pacific Railroad (which secretly provided the funding for the endeavor) lines in El Centro, California, the 148-mile (238 km) route of the SD&A originated in San Diego, California and terminated in El Centro, California. The company charter was executed on December 14, 1906, and the groundbreaking ceremony was held the following September. Numerous delays (including government intervention during World War I) delayed the completion of the line to November 15, 1919. Damage to the lines from both natural disasters and sabotage exerted great financial pressure on the company, and in 1932 Spreckels’ heirs sold their interests in the railroad to the Southern Pacific, which was named the San Diego & Arizona Eastern Railway (SD&AE).
