context_page_description: The San Francisco Municipal Railway is the public transit system for the city and county of San Francisco, California.
  In 2018, Muni served 46.7 square miles with an operating budget of about $1.2 billion. In ridership terms, Muni is the seventh largest transit system in the United States, with 210,848,310 rides in 2006 and the second largest in California behind Metro in Los Angeles.
  With a fleet average speed of 8.1 mph, it is the slowest major urban transit system in America and one of the most expensive to operate, costing $19.21 per mile per bus and $24.37 per mile per train. However, it has more boardings per mile and more vehicles in operation than similar transit agencies.
  Muni is an integral part of public transit in the city of San Francisco, operating 365 days a year and connecting with regional transportation services, such as Bay Area Rapid Transit, Caltrain, SamTrans, Golden Gate Transit, and AC Transit. Its network consists of 54 bus lines, 17 trolley bus lines, 7 light rail lines that operate above ground and in the city's lone subway tube, 3 cable car lines, and 2 heritage streetcar lines, the E Embarcadero and F Market.
context_section_description: Muni operates about 1,000 vehicles: diesel, electric, and hybrid electric transit buses, light rail vehicles, streetcars, historic streetcars, and cable cars. Many buses are diesel-powered, but more than 300 are zero emissions trolleybuses powered by overhead electrical wires. The electricity to run all of Muni's trolleybuses and streetcars comes from the Hetch Hetchy Reservoir in Yosemite National Park.
  In 2006, Muni purchased 86 hybrid electric transit buses from Orion Bus Industries that are diesel-fueled but feature lower emissions and 19% reduced fuel consumption.
  All Muni lines except for cable cars are wheelchair accessible. All bus lines have bicycle racks, but streetcars and cable cars do not. Because of San Francisco's geographical makeup (the city having neighborhoods located on hilltop-like areas, making it difficult for vehicles to drive up or down the streets), Muni operators were banned from using low-floor buses on certain routes with streets requiring buses or trolleybuses that are capable of reaching steep grades, but as of 2013, high-floor vehicles are no longer available to be purchased by Muni.
  The longest Muni line is the 24.1-mile (38.8 km) 91 Owl, a nighttime-only route that blends several other routes together, while the longest daytime route is the 17.4-mile (28.0 km) 29 Sunset. The shortest route is the peak-hour only 88 BART Shuttle at 1.4 miles (2.3 km), while the shortest off-peak route is the 39 Coit at 1.6 miles (2.6 km). The steepest grade climbed by Muni vehicle is 23.1% by a diesel bus on the 67 Bernal Heights line, 22.8% by a trolleybus on the 24 Divisadero line, 21% by a cable car on the Powell-Hyde line, and 9% by a streetcar on the J Church line.
  The busiest Muni bus corridor is the Geary corridor. The two major routes that operate on the corridor, the 38 Geary and 38R Geary Rapid, travel 6.5 miles (10.5 km) in the east–west direction along the Geary corridor, and has an average speed of only 8 miles per hour (13 km/h), taking over 50 minutes to travel from the Richmond District to the Transbay Terminal when operating on schedule. As of 2015, the corridor has a total of 55,270 average daily boardings, making it the second busiest transit corridor west of the Mississippi after the Los Angeles Metro Wilshire transit corridor.
  At Powell and Market Streets and California and Market Streets, three types of rail gauges come within a few hundred feet of each other: Bay Area Rapid Transit's 5 ft 6 in (1,676 mm) broad gauge (which is underground in the lower level of the tunnels), Muni Metro's 4 ft 8 ¹⁄₂ in (1,435 mm) standard gauge (also underground in the upper level of the tunnels), and the San Francisco cable car system's 3 ft 6 in (1,067 mm) narrow gauge (at street level a few hundred feet away to the north of Market Street in both cases). The F Market heritage railway, which is also standard gauge, is also present here, at street level on Market Street. The rail lines, however, do not physically intersect.
