San Francisco Cable Cars

The San Francisco cable car system is the last manually operated one in the world. Cars carry no engine; a steel cable runs in a slot under the street at a constant 9.5 miles per hour, and the gripman closes a set of jaws onto it. Andrew Smith Hallidie tested the first line, the Clay Street Hill Railroad, at 4am on August 2, 1873.

Four in the Morning

On the second of August, 1873, at four in the morning, a Scottish-born engineer named Andrew Smith Hallidie stood at the top of Clay Street and prepared to test something nobody had built before. Hallidie made wire rope for the mines, and he had an idea: run that rope in a slot under the street, keep it moving, and let a car grip it to be pulled uphill. He raised the money largely from people who lived on Clay Street and wanted the hill solved. The test worked. Regular passenger service on the Clay Street Hill Railroad began on the first of September that year, and the fare was five cents. Look at the steepness of the block in front of you and imagine a horse trying to climb it in the mud. Then imagine what it meant to never need that horse again.

On the ground

Checked against official sources on the dates shown. Nothing here is a price or an opening hour — those go stale.

Which way in

  • Any brown-and-white cable car sign post

    Boarding is not restricted to the turntables at the ends of the lines. Every sign post is a stop.

    checked 2026-09-07
  • One block up from the Powell and Market turnaround

    Cars are not filled to capacity at the turnaround. Walk to the next stop, wait at the curb and wave when the car is about half a block away, and you can usually get straight on.

    checked 2026-09-07
  • The California Street line

    It is far less crowded than the two Powell lines; you can board it without waiting at almost any hour.

    checked 2026-09-07
  • Bay and Taylor, coming back from Fisherman's Wharf

    The Powell-Mason terminal there has a much shorter line than the Powell-Hyde turnaround at Hyde and Beach.

    checked 2026-09-07
  • The outside running board

    A Powell car has fourteen hanging-on spots, eight on one side and six on the other. Traffic passes about twelve inches from your body.

    checked 2026-09-07
  • Holding on outside

    Muni's rule for riders on the outside poles: hold on tight and do not lean outward.

    checked 2026-09-07

When to come

  • Before nine in the morning, or after eight at night

    Those are the two windows without a line.

    checked 2026-09-07
  • Half past six at the Powell Street turnaround

    A rider reports doing all three lines from there at that hour with no crowding.

    checked 2026-09-07
  • After dark, on the California line

    It runs over Nob Hill past the Mark Hopkins and the Fairmont.

    checked 2026-09-07

When not to

  • Powell and Market from mid-morning, in summer

    The queue runs to an hour and a half. Riders report it already extremely long around ten.

    checked 2026-09-07
  • Intermediate stops in peak season

    Cars arrive with room for about two more people. Twenty people ahead of you at the stop is ten cable cars.

    checked 2026-09-07

Where the shot is

  • The Powell-Hyde stop at the top of the crooked Lombard block

    Cars coming down the eight switchbacks. Get off and walk down Lombard for the angle.

    checked 2026-09-07
  • The right-hand side of the car going to Fisherman's Wharf, the left side coming back

    The bay, both directions. Pick your side as you board.

    checked 2026-09-07

Eat nearby

  • Golden Gate Fortune Cookie Factory, 56 Ross Alley

    Two blocks from the Powell line at Jackson: walk down Jackson past Stockton and Ross Alley is on the right. One block from the Cable Car Museum.

    checked 2026-09-07

Where next

  • cable-car-museum-sf walk

    Both Powell lines stop outside it, in both directions. The deck inside looks down on the engines and winding wheels pulling the cable you just rode.

    checked 2026-09-07
  • ghirardelli-square-sf walk

    One block west of the Powell-Hyde terminal at Beach Street, at the bottom of the steepest grade in the system.

    checked 2026-09-07
  • ferry-building-sf streetcar

    The F-Market historic streetcar connects the terminals of all three cable car lines, so ride a cable car one way and take the F back.

Frequently asked

Who invented the San Francisco cable car?
Andrew Smith Hallidie, a Scottish-born manufacturer of wire rope for the gold and silver mines. He patented a grip that could clamp a rigid jaw onto a moving underground cable, then raised most of the construction money from residents of the hill he wanted to solve. He was a rope engineer, not a transit man.
How fast does a San Francisco cable car travel?
Nine and a half miles an hour, and nothing else. The underground cable runs at that single speed, so a car that has gripped it matches the cable exactly, with no accelerator and no gearbox. The only variation comes downhill, when the gripman lets go and controls the descent on the brakes alone.
How many cable car lines are left in San Francisco?
Three. Before 1906 the network covered roughly 53 miles of track and reached the Presidio, Golden Gate Park, the Castro and the Mission. Electric streetcars were cheaper to run and replaced most of it. What remains is the steepest fraction of the original system, and it is a National Historic Landmark.
Why were the cable cars never scrapped?
In 1947 city leadership proposed replacing them with buses. Friedel Klussmann organized the Citizens' Committee to Save the Cable Cars, took the question to the ballot, and won in a landslide. Minimum service levels for the lines are now written into the San Francisco city charter, so removing them takes a vote rather than a memo.
Where can you see the machinery that pulls the cars?
At the powerhouse on Mason Street, which doubles as the Cable Car Museum. A viewing gallery looks down on the great winding wheels that keep the cables moving under the streets, and the noise explains the system better than any diagram. The last surviving grip car from the 1873 Clay Street line, car number 8, sits in the same building.
