It relies on private contributions to help maintain San Francisco’s fleet of historic streetcars in service on the E Embarcadero and F Market & Wharves lines.

On March 4, 2000, the F Market line was extended to use the new tracks to travel between the Ferry Building and Fisherman's Wharf at the northern end of the waterfront.

[4] By 2008, F Market streetcars were carrying an average of 20,000 riders per day, and were so overcrowded that drivers were sometimes forced to skip stops.

[5] For comparison, the Muni Metro system carried an average of 130,000 passengers per day through the Market Street subway in 1999.

Its volunteers also clean the cars' interiors at the Castro Street Terminal to improve rider experience.
