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.
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 88 BART Shuttle at 1.4 miles (2.3 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, and 21% by a cable car on the Powell-Hyde line.
The busiest Muni bus line is the 38 Geary, which travels 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.
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 is also present here, at street level on Market Street. The rail lines, however, do not physically intersect.
The F Market and Wharves line uses the same standard gauge as the Muni Metro, and in fact uses the J Church tracks to travel between its regular route and the storage facility near Balboa Park Station.

Famous quotes containing the word statistics:
“O for a man who is a man, and, as my neighbor says, has a bone in his back which you cannot pass your hand through! Our statistics are at fault: the population has been returned too large. How many men are there to a square thousand miles in this country? Hardly one.”
—Henry David Thoreau (1817–1862)
“July 4. Statistics show that we lose more fools on this day than in all the other days of the year put together. This proves, by the number left in stock, that one Fourth of July per year is now inadequate, the country has grown so.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Maybe a nation that consumes as much booze and dope as we do and has our kind of divorce statistics should pipe down about “character issues.” Either that or just go ahead and determine the presidency with three-legged races and pie-eating contests. It would make better TV.”
—P.J. (Patrick Jake)
