August 2, 1873 — In the wee small hours of a misty San Francisco night (they didn’t call the month “Fogust” back then, but it was), a new type of transit was about to be inaugurated. An endless wire rope clattered beneath Clay Street. An odd open vehicle sat on the rails at the top of the hill. Standing by was Andrew Smith Hallidie, a Scot who had experience using wire rope in the mining business, and was part of the team promoting this new technology, aimed at making horsecars obsolete.
The operator of the little car peered out over the edge of the steep hill and decided, “No.” As the story goes, Hallidie himself stepped up, gripped the wire rope, went down the hill safely, and the cable car was born.
Some historians argue over the details of that opening run, but we’re not going to get into that here. We’ll just say that the first line, on Clay Street, became part of a longer line in the late 1880s that ran one way on Clay and the other on Sacramento Street. At that point, it began being served by new single-end cable cars without the trailers you see in this engraving from Wikimedia Commons.
On April 18, 1906, earthquake and fire wiped out identical cable cars that served Powell Street, so the cars from the Sacramento-Clay line were moved to Powell, where many still run to this day. Larger double-end cable cars took over on the Sacramento-Clay line and lasted until 1942 when the line was shut. One of the last group of Sacramento-Clay cable cars (Car 19, built in 1907) has been restored, thanks in part to advocacy from Market Street Railway, and is stored upstairs in the cable car barn at Washington and Mason Streets. Downstairs, in the Cable Car Museum, the last surviving original car from the Clay Street Hill Railroad, Grip Car 8, is on display.
While you haven’t been able to ride a cable car on Clay Street for 76 years, you can still ride cable cars that ran on Clay Street back in the 1890s. Current Powell cable car 11 (above), built in 1893 by Carter Brothers and recently refurbished by Muni’s shops, ran on the Sacramento-Clay line until 1906, and was recently repainted into its original Sacramento-Clay livery from the 1890s at Market Street Railway’s suggestion.
The other surviving Powell cable cars that once ran on Clay Street include numbers 2, 3, 5, 6, 7, 10, 12, 16, 17, 20, 22, 23, 24, 25, 26, and 27. (Thanks to Joe Thompson’s Cable-Car-Guy website for the authoritative roster.) If you climb aboard any of these cars on the Powell-Hyde or Powell-Mason lines today, you’re experiencing a connection back to the first street on which cable cars ever ran.
Happy 145th Anniversary of the first successful cable car system!
This week is the 70th anniversary of the failed effort by Mayor Roger Lapham (at left in the photo above) to “junk the cable cars.” It’s truly something to celebrate, and it has engendered several news articles, such as
