SF Cable Car Delays Hit California Line

San Francisco's California Street cable car line experienced traffic-related delays Saturday, forcing riders to seek alternative routes. The San Francisco Municipal Transportation Agency confirmed the service disruption December 28 and directed passengers to use the 1 California bus route instead. The specific cause of the traffic conditions wasn't immediately available.

Cable Cars Face Unique Traffic Challenges

Cable cars operate on fixed cables along shared streets, making them vulnerable to traffic interference unlike other rail transit, according to SFMTA information. The California Street line is one of three cable car routes the agency operates with a fleet of 40 vehicles. The system has served as San Francisco's iconic transit mode since 1873 and became the nation's only moving National Historic Landmark in 1964. Officials didn't specify how long the delay lasted or when normal service resumed.
