F Stock

It originally ran as a shuttle between 10th Avenue and 33rd Avenue, and was later extended east along Geary and Market Street to the Ferry Building to the east, and along 33rd Avenue, Balboa, 45th Avenue and Cabrillo to Great Highway to the west. The line was replaced with the 38 Geary bus route on December 29, 1956.
Currently there are plans to construct a bus rapid transit corridor on Geary Boulevard between Van Ness Avenue and 33rd Avenue, intended to begin operation in 2011. Funding has not been identified to build rail in this corridor, however the BRT project includes the possibility of "light rail ready" construction that would enable a future conversion to rail if funding becomes available.
Any future light rail line would run on the surface from 48th Avenue to Laguna Street along the route of the existing 38L-Geary Limited.

Under current proposals, the rail line would continue as a subway under either Post St or Geary St. The Post St alignment would have underground stations at Van Ness Ave, Leavenworth St, Union Square, Montgomery St, and the Transbay Terminal.The Montgomery St station would be a transfer point with the existing Market Street subway.
C Geary-California
The C California (also known as the C Geary-California) was a streetcar route that ran from the Ferry Building along Market Street, Geary, 2nd Avenue, Cornwall, and California to 33rd Avenue. The route was cut short in 1950 to California and 2nd Avenue with the opening of the 1 California bus line, and was removed along with the B Geary on December 29, 1956. Part of the route is currently under study to be restored for Bus Rapid Transit.
This route was created shortly after the Market Street Railway's franchise expired on California street.

By 1950, the line was essentially a short-turn version of the B Geary streetcar route, which continued out to Ocean Beach.
D Geary-Van Ness
The D Geary-Van Ness was a streetcar route created on August 15, 1914that originally ran from the Ferry Building along Market Street, Geary, Van Ness, and Chestnut to Scott. In 1918, the route was changed to operate on Union Street instead of Chestnut, and was extended along Steiner Street and Greenwich Street and into the Presidio later that year.
The route was replaced with buses on March 18, 1950. This is one of four routes planned as a result of the 1915 Panama-Pacific International Exposition.Today, parts of the Geary and Van Ness Corridors it once traveled is currently up for study for Bus Rapid Transit, and possibly, restoration of light rail transit in the area.
E Union
The E Union was a streetcar route that ran from the Ferry Building to the Presidio via The Embarcadero, Washington/Jackson, Columbus, Union, Larkin, Vallejo, Franklin, Union, Baker and Greenwich into the Presidio. The route was replaced on April 21, 1947 with the 41-Union bus route, which still runs today. This is one of four routes planned as a result of the 1915 Panama-Pacific International Exposition.
F Stockton
The F Stockton was a streetcar route that ran from Market and Stockton to the Marina District via Stockton, Columbus, North Point, Van Ness, and Chestnut to Laguna.

In 1916, the line was extended from Chestnut and Laguna to Chestnut and Scott, and was extended in 1947 from Market and Stockton down 4th Street to the Southern Pacific terminal on Townsend. The route was replaced on January 20, 1951, with the 30-Stockton bus route, which still runs today, and is notable for being the slowest trolley bus route in the City of San Francisco. This was one of four routes planned as a result of the 1915 Panama-Pacific International Exposition. Today, the F designation is used for the F Market & Wharves historic streetcar route.
H Potrero
The H Potrero streetcar line that was created on August 15, 1914 to serve the Panama-Pacific International exposition. It ran from Army Street (Now Cesar Chavez Street) and Potrero to a terminal inside Fort Mason, via Potrero, Division, 11th Street and Van Ness.The southern terminal was cut back to San Bruno and Wilde in 1947, and in in 1948 the northern terminal was cut back to Van Ness and Bay. The route was replaced on March 19, 1950 with the 47 Potrero bus line. The 47 line has since been changed to run and no longer runs on Potrero, and the only bus line that follows the old H line is the nighttime-only 90 Owl.
A possible bus rapid transit project is currently in the works with the San Francisco County Transportation Authority.

A feasibility study was conducted earlier in 2007, and may open as soon as 2011. The SFCTA currently does not have plans to revive the H-Potrero streetcar line.
Temporary routes
The G Exposition, I Exposition, and J Exposition were temporary streetcar lines that were created in 1915 and 1916 to serve the Panama-Pacific International Exposition. The G line was a combination of the E and F routes, running from Market and Stockton to the Presidio. The I line only ran for three days in February 1915, from 33rd Avenue and Geary via Geary, Van Ness, Chestnut, Scott, Greenwich and Steiner to Union.The J line, which is unrelated to the current J Church line, ran via Columbus from the Ferry Building to Fort Mason and later to Chestnut and Scott.
The O Van Ness line operated briefly between June 1, 1932 and July 15, 1932, along part of the E Union from Van Ness and Union to the Ferry Building.
