context_page_description: The San Francisco Municipal Railway is the primary public transit system for San Francisco, California. Muni is part of the San Francisco Municipal Transportation Agency, which is also responsible for the streets, parking, traffic signals, and other transportation in the city. In 2019, Muni had the eighth-highest ridership among systems in the United States, with an average weekday ridership of 684,600. Service is operated to all parts of San Francisco - including Treasure Island - as well as small sections of Daly City and Marin County.
  Muni operates seven light rail lines in the Muni Metro system, two streetcar lines, and three cable car lines. Daytime bus service includes 44 local routes, 5 limited-stop "Rapid" routes, and 15 peak-hour express routes. Four additional express routes provide weekend service to the Marin Headlands, service to Oracle Park and the Chase Center and supplement BART in the early morning. Overnight night bus "Owl" service - part of the All Nighter network - includes eight 24-hour routes, two night-only routes, three bus replacements of Muni Metro lines, and five weekend early-morning Muni Metro replacement lines.
context_section_description: On five high-ridership corridors, local buses are supplemented with rapid buses with limited stops. The Rapid routes largely follow the route of the local buses, with some variations; at times when the 5R and 9R operates, the 5 and 9 are cut back to a shorter route. The 5R, 9R, and 28R operate only on weekdays until 7pm; the 14R and 38R operate every day until 7pm.
