The San Francisco trolleybus system forms part of the public transportation network serving San Francisco, in the state of California, United States. Opened on October 6, 1935, it presently comprises 15 lines, and is operated by the San Francisco Municipal Railway, commonly known as Muni (or the Muni), with around 300 trolleybuses. In San Francisco, these vehicles are also known as "trolley coaches" (a term that was the most common name for the mode in the United States in the middle decades of the 20th Century).
One of only five such systems currently operating in the U.S., the Muni trolley bus system is the second-largest such system in the Western Hemisphere, after that of Mexico City. A particularly notable feature of its operations are very steep grades. The system includes the single steepest known grade on any existing trolley bus line in the world, specifically 22.8% in the block of Noe Street between Cesar Chavez Street and 26th Street on route 24-Divisadero, and several other sections of Muni trolley bus routes are among the world's steepest.
The Muni trolley bus system is complementary to the city's rail-bound Caltrain, Bay Area Rapid Transit, Muni Metro and cable car system. In addition, it shares some of its overhead wires with the F Market & Wharves streetcar line.
Trolley buses currently operate the following Muni routes:
As of January 2010, the exclusively high-floor Muni trolley bus fleet included 313 serviceable vehicles, comprising three different types, of which 240 were conventional length (two-axle) buses and 73 articulated buses. Of the latter, 40 were New Flyer E60 vehicles (built in 1993–94); 12 of these were retired in early 2013, and the remaining 28 were retired in early January 2015. All of the then-remaining 273 trolleybuses were built by Electric Transit, Inc. (ETI), mostly in 2001–03, the 240 40-foot units being model 14TrSF and the 33 articulated units being model 15TrSF.
