But what happens when a cable car reaches the end of its life? It turns out, the process is more intimate than you'd think. These machines don't just get scrapped. Each car is hand-maintained at the cable car barn on Mason Street by a small team of craftspeople who know every plank, every grip, every bell. When a car finally reaches its "last heartbeat" — the point where the wear is beyond practical repair — it's retired with something approaching reverence. Parts get salvaged, wood gets repurposed, and a piece of San Francisco history quietly exits the stage.

It's a reminder that the things worth preserving require actual investment, actual skill, and actual care — concepts that seem increasingly foreign to city government when it comes to, well, everything else.

The cable car system costs real money to run. Fares don't come close to covering operations. And yet, almost nobody argues it should be shut down, because everyone understands the value of maintaining something irreplaceable. Funny how that logic never extends to keeping the rest of the city functional.

Meanwhile, the city that meticulously restores century-old cable cars can't figure out how to fill a pothole, keep a BART escalator running, or build housing at a pace that doesn't make your eyes water. One local resident put it well, reflecting on old SF real estate listings: "They used to be more attainable," they sighed, comparing income-to-house-price ratios from decades past to today's absurdity. An 8-bedroom in Bernal Heights once listed for the inflation-adjusted equivalent of $443,000. Today you'd be lucky to get a studio for that in most neighborhoods.

The cable cars survive because someone decided they were worth fighting for, worth funding, and worth protecting from the bureaucratic impulse to modernize everything into mediocrity. Maybe the city should take notes. Some things — affordable neighborhoods, functional transit, public safety — deserve the same treatment.

Not everything old needs to be replaced. Sometimes it just needs people who give a damn.
