Cable Car Museum unexplained noises

The San Francisco Cable Car Museum houses historic cable-car winding machinery and is a frequent stop on city ghost tours because staff and visitors have reported unexplained clanking, phantom bell ringing, and odd mechanical noises attributed by some to non-obvious sources. These reports are recorded in local guidebooks, oral histories, and press coverage alongside the museum’s documented role preserving the cable car system. The accounts are anecdotal and discussed in tour and cultural-history contexts rather than validated by formal scientific study.
