At each end of its journey, the cable car is put on a rotating platform and manually rotated 180 degrees to face the other way. Here, an operator rotates a car at Fisherman's Wharf. Here's a video of the same process at Market Street.
Thanks a lot to everyone who commented on my photos, or even stopped by for a visit. The comments have been pouring in pretty fast and I'm finding it increasingly difficult to reply to each individually. I'd rather spend that time in viewing others' photos and commenting there. But I do read each comment individually, and if you ask me something specific, I'll answer that.
