Public transportation
Public transit solely within the city of San Francisco is provided predominantly by the San Francisco Municipal Railway (Muni). The city-owned system operates both a combined light rail/subway system (the Muni Metro) and a bus network that includes both trolleybuses and standard diesel buses. Additionally, Muni runs the F Market historic streetcar line and the iconic San Francisco cable car system.
Commuter rail is provided by two complementary agencies. Bay Area Rapid Transit (BART) is the regional rapid transit system which connects San Francisco with the East Bay through the Transbay Tube. It also extends south of the city through northern San Mateo County, to the San Francisco International Airport, and Millbrae. The Caltrain rail system runs from San Francisco along the Peninsula down to San Jose.
The Transbay Terminal serves as the terminus for long range bus service (such as Greyhound) and as a hub for regional bus systems AC Transit (to Alameda County), SamTrans (San Mateo County), and Golden Gate Transit (Marin and Sonoma Counties). Amtrak also runs a shuttle bus from San Francisco to its rail station in Emeryville.
A small fleet of commuter and tourist ferries operate from the Ferry Building and Pier 39 to points in Marin County, Oakland, and north to Vallejo in Solano County.
