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
