From 1912, when the San Francisco Municipal Railway began service, until 1956, when redevelopment projects led by Justin Herman included their removal and replacement with buses, the A Geary-10th Avenue, B Geary, C Geary-California, and D Geary-Van Ness lines all ran along Geary from Market Street to 10th Avenue, 33rd Avenue, 2nd Avenue, and Van Ness Avenue, respectively. The B Geary line eventually reached Playland and Ocean Beach after turning south at 33rd Avenue and then west on Balboa Avenue. At 33rd Avenue, streetcars of the Market Street Railway came down from Clement Street and continued along to the end of Geary at 48th Avenue where they turned north and entered a private right of way at Point Lobos Avenue to reach a car barn at Sutro Baths. This made the entire length of Geary from Market Street to 48th served by streetcars. If and when a future streetcar line is built along Geary, it will likely once again use the "B" letter.
