Regular Muni light rail routes are more than a quarter-century removed from their surface running through downtown.  And PCC units are long gone from the lines that utilize the subway.   But that distinguished old class of cars, and surface running along Market St., thrive on the reborn F-Market & Wharves Historic Streetcar Line. 

Although there was earlier historic streetcar service on Market in the 1980s, the F-line (as it is commonly called) as a regular feature dates to 1995.  With later expansion of the route, it travels from the Castro District through downtown, and then does a series of jogs to head along The Embarcadero, and eventually onto other surface streets to the west, through the Fisherman's Wharf area. 

Full runs traverse, leisurely, a distance of nearly six miles, the longest historic streetcar route in the country.  There are close to thirty stops -- and it can take up to an hour or so to go from end end to end, depending on traffic conditions.   

The car in this scene is turning off Market onto Steuart St., close to the Ferry Building.  There are also other, and older, kinds of equipment in use on the line.
