The Cable Car Museum is a free museum in the Nob Hill neighborhood. It contains historical and educational exhibits on the San Francisco cable car system, which can itself be considered a working museum. The entrance to the museum is located at the intersection of Washington and Mason. The hours of operation are 10 AM to 6 PM between April 1 and September 30 and from 10 AM to 5 PM between October 1 and March 31, apart from some public holidays.
The museum contains several examples of mechanical devices, detailed models and three antique cable cars from the 1870s. They are the #46 grip car and #54 trailer from the Sutter Street Railway, as well as the #8 grip car from the Clay Street Hill Railroad, the only surviving car from the first cable car company.
The museum is part of the complex that includes the cable car powerhouse, which drives the cables and the car depot. An observation deck allows visitors to view the powerhouse and its engines and wheels that pull the cables. Vistors may also descend below the junction of Washington and Mason streets in order to view the cavern where the cables are routed out to the street.
The Cable Car Museum was established in 1974 and is run by the Friends of the Cable Car Museum nonprofit organization.
