The San Francisco Municipal Railway (Muni) is the public transit system for San Francisco, California. Several bus, trolleybus, streetcar/light rail, and cable car routes were historically served, but have been discontinued. It began service on December 28, 1912, with two streetcar routes on Geary Boulevard and continued to expand operations. In 1944, the city acquired the largest remaining private transit agency in San Francisco, the Market Street Railway, and began operating its former services. Many modern routes are amalgamated from earlier lines, while some corridors no longer see regular Muni service.
