The Cable Cars of San Francisco

I was extremely impressed with the cable car system in San Francisco on our recent visit there. The San Francisco cable car system is the world's last manually operated cable car system and as such is a very big tourist attraction to that town.

We had seen these cars on our first visit there in 1970, but to be honest, I never really thought about them until we actually saw them in operation this time around.


The cables which are about 1 1/2" (31.75mm) run under the streets of the 3 lines, the Powell-Hyde, the Powell-Mason and the California lines.  The cable cars are operated by a 'Gripman' and a conductor. The gripman moves the lever which 'grips' the cable which is running at a constant speed,  and the car moves forward. At the next stop, he releases the cable and applies the brake to stop the car from rolling. It's quite a tricky job being a gripman. they need to be alert to release the 'grip' when they cross another line to avoid dragging that cable up.

San Francisco's streets are sometimes quite steep so the conductor at the back helps by putting on manual brakes to assist descents. 


The machines that run the cables all over the town are in the cable barn (and museum). The car barn is located between Washington and Jackson streets just uphill of where Mason Street crosses them. Cars reverse into the barn off Jackson Street and run out into Washington Street, coasting downhill for both moves.


There are four separate cables: one for the California Street line, one each for the separate parts of the Powell-Hyde and Powell-Mason lines, and one for their common section.


The cable cars are not only a tourist attraction, but they are used by the locals also to get around the city. When the cars are full, people just hang on to the railings.


It is amazing how these cable cars perform on the sometimes very steep hills of the city.



There are turntables at the three terminals served by the Powell-Hyde and Powell-Mason lines, and these two lines are served by a common fleet of single-ended cable cars. Cable cars on California Street, however, have cabs at both ends, so the terminals are single-track stubs and the operator only switches ends.

As I said, I was very impressed. Well done San Francisco.

  1. Great informative report Bill. ( TOH, Diane, should be impressed?)
    1970 eh? Well we have that in common, my first visit also after my "idiotic" dreams of leaving TPNG for Canada, to be precise, Medicine Hat, Alberta and in their worst winter for years. Needless to say, I never saw Medicine Hat! Just one long train trip, Vancouver to Montreal, 3 days/nights of looking at white stuff ( whatever that is called??).
    I got the Cable car a couple of times down to Fishermans Wharf and hung out like shown. I wonder can you still do this? The cable car hardly went through the "sound barrier"!!!
    You were very lucky to have been shown all this information. It's a wonder that people still are able to cling on, with all this stuff of W.H & S crap. Anyone who would fall off these days, would obviously be on drugs or severely intoxicated. Serves them bloody right.
    Take the famed Cable Cars out of SFO, and SFO would not be the same, would it?
    Safe travels in the new car to Sydney.
    Looking forward to reports from down there from the two of you.
    Cheers
