If you've ever wondered how cable cars work, this nifty museum explains (and demonstrates) it all. Yes, this is a museum, but the Cable Car Museum is no stuffed shirt. It's the living powerhouse, repair shop, and storage place of the cable car system and is in full operation. Built for the Ferries and Cliff House Railway in 1887, the building underwent an $18-million reconstruction to restore its original gaslight-era look, install an amazing spectators' gallery, and add a museum of San Francisco transit history
