The private Market Street Railway opened a branch - built in just six days - of its Mission Street line along Ocean Avenue to Victoria Street on December 4, 1895 to serve the new Ingleside Racetrack. The line was extended to the Ingleside House (where Ocean Avenue now meets Junipero Serra Boulevard) shortly thereafter. The 1906 earthquake damaged many cable car and streetcar lines; the URR resumed service on the Ocean Avenue (12) line on May 6, 1906.
