The San Francisco and San Mateo Electric Railway ( SF&SM ) , later part of the Market Street Railway system , began operation on April 27 , 1892 . The line ran on 30th Street between Guerrero Street and Chenery Street . After the 1906 San Francisco earthquake , the URR rerouted the San Mateo line to Mission Street ; Embarcadero – Daly City route 26 and Embarcadero – Sunnyside route 10 continued to operate on the ex-SF & SM on Church Street . Service on Church over the former SF&SM route ended on January 27 , 1940 , when route 10 was discontinued
