Muni operates seven light rail lines in the Muni Metro system, two streetcar lines (E Embarcadero and F Market & Wharves), 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 (home of the San Francisco Giants) and the Chase Center (home of the Golden State Warriors) 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. Fourteen local routes (two only at certain times), one rapid route, and four Owl routes run as electric trolleybuses. Muni service operates out of ten yards and garages: one cable car barn, three light rail / streetcar yards, two trolleybus garages, and four bus garages.
