Though the elegant California Southern depot had served San Diego for nearly three decades, the station was not adequate to handle the expected flood of visitors through the "Silver Gate" in 1915. In fact, the Santa Fe had considered replacing the aging "D" Street station with a larger, more modern edifice. Plans were drawn up for a new station complex in the Mission Revival Style, befitting the upcoming Exposition. The large, graceful palm trees that graced the old depot were boxed and stored for re-planting alongside the new building. Construction began on a site just east of the existing structure on January 15, 1914, and was completed on December 31, at a total cost of $300,000. A Fred Harvey Company lunch counter and dining room were incorporated into the floor plan. The old wooden structure was razed during the few days before the opening; the clock tower was ceremonially toppled on March 7, 1915.
