The facility opened for business on March 8. Oliver J. Stough, the last surviving veteran of the Mexican–American War, was given the honor of purchasing the first ticket. At the outset, the Santa Fe had three daily local trains and one express train running between Los Angeles and San Diego. During the exposition nine scheduled trains ran on during the week (eight only made stops at Fullerton and Santa Ana, while the ninth was a local that stopped at all of the "Surf Line" stations). Twelve trains operated on weekends, many running in multiple sections. Four helper locomotives were assigned to the Sorrento Grade to help trains over the hill for the duration of the Exposition.
