1918 photo of the Santa Fe Depot (Union Station) with trolley cars out front. The depot was designed by architects John R. Bakewell and Arthur Brown, Jr., and built by the Atchison, Topeka and Santa Fe Railway. It opened on March 8, 1915, replacing California Southern Railway's 1887 Victorian depot. The opening date was later than scheduled due to controversy over closing B Street. The new depot was built to serve travelers visiting the 1915 Panama-California International Exposition, which opened January 1, 1915.
