The San Francisco Municipal Railway (SF Muni or Muni), is the public transit system for the City and County of San Francisco. It operates a system of bus routes (including trolleybuses), the Muni Metro light rail system, three historic cable car lines, and two historic streetcar lines. Previously an independent agency, the San Francisco Municipal Railway merged with two other agencies in 1999 to become the San Francisco Municipal Transportation Agency (SFMTA). In 2018, Muni served with an operating budget of about $1.2 billion. Muni is the seventh-highest-ridership transit system in the United States, with rides in , and the second-highest in California after the Los Angeles County Metropolitan Transportation Authority. Operations Most bus lines are scheduled to operate every five to fifteen minutes during peak hours, every five to twenty minutes middays, about every ten to twenty minutes from 9 pm to midnight, and roughly every half-hour for the late night "owl" routes. On weekends, most Muni bus lines are scheduled to run every ten to twenty minutes. However, complaints of unreliability, especially on less-often-served lines and older (pre-battery backup) trolleybus lines, are a system-wide problem. Muni has had some difficulty meeting a stated goal of 85% voter-demanded on-time service. All Muni lines run inside San Francisco city limits, with the exception of several lines serving locations in the northern part of neighboring Daly City, and the 76X Marin Headlands Express line to the Marin Headlands area on weekends and major holidays. Most intercity connections are provided by BART and Caltrain heavy rail, AC Transit buses at the Transbay Transit Center, and Golden Gate Transit and SamTrans downtown. Bus and car stops throughout the city vary from Metro stations with raised platforms in the subway and at the more heavily used surface stops, to small shelters to signposts to simply a yellow stripe on a utility pole or on the road surface. 70% of stops are spaced closer than recommended range of apart. Name and logo Muni is short for the "Municipal" in "San Francisco Municipal Railway" and is not an acronym; thus, when it is written in plain text, only Muni (not MUNI) is correct. The Muni metro is often called "the train" or "the streetcar." Most San Francisco natives use 'Muni' when speaking about the system (Metro & buses) in general. The E Embarcadero and F Market & Wharves lines are referred to by Muni as a
