Union Station in San Diego, California, is a train station built by the Atchison, Topeka and Santa Fe Railway to replace the existing Victorian-style structure erected in 1887 for the California Southern Railroad Company. The Santa Fe Depot (as it was originally designated) officially opened on March 8, 1915, to accommodate visitors to the Panama-California Exposition. The depot was completed during a particularly optimistic period in the City's development, and represents the battle waged by the City of San Diego to become the West Coast terminus of the Santa Fe Railway system’s transcontinental railroad, a fight that was ultimately lost to the City of Los Angeles.
