Muni Metro Light Rail
Muni Metro is the United States' third-busiest light rail system, operating a fleet of 151 light rail vehicles (LRV) with an average weekday ridership of 173,500 passengers.
The Muni Metro system consists of 71.5 miles (115.1 km) of standard-gauge track, seven light rail lines (six regular lines and one peak-hour shuttle), three tunnels, nine subway stations, twenty-four surface stations and eighty-seven surface stops.
All subway and surface stations are wheelchair-accessible. In addition, many surface street stops are also wheelchair-accessible, often consisting of a ramp leading up to a small platform for boarding. Above ground, there are 24 surface platform stations. Two stations, Stonestown and San Francisco State University, are located at the southwestern part of the city, while the rest are located on the eastern side of the city, where the system underwent more recent expansion as part of the Embarcadero extension and the Third Street Light Rail Project. However, many of the stops on the system are surface stops consisting of anything from a traffic island to a yellow-banded "Car Stop" sign painted on a utility pole.
Muni Light Rail Facilities
Muni Metro has two rail yards for storage and maintenance:
- Green Yard or Curtis E. Green Light Rail Center is located adjacent to Balboa Park Station and serves as the outbound terminus for the J Church, K Ingleside, and M Ocean View lines. The facility has repair facilities, an outdoor storage yard and larger carhouse structure. The facility was renamed for former Muni head Curtis E. Green in 1987.
- Muni Metro East is a newer facility opened in 2008 and is located along the Central Waterfront on Illinois and 25th streets in the Potrero Hill neighborhood, a block from the T Third Street Line. The 180,000 square foot maintenance facility with outdoor storage area is located next to Northern Container Terminal and the former Army Pier.
- The Cameron Beach Yard facility was originally named the Geneva Yard. Born in 1902 as a Market Street Railway facility, it had a large brick office building, adjoining power house and separate car house. The original office and power house structures remain, although unused by Muni. A new shed or canopy was built and dedicated to Cameron Beach, who had been a member of the Muni's Board of Directors. The current yard has a body and paint shop, and houses Muni's F Line cars.

Muni Metro History
On February 18, 1980, the Muni Metro was officially inaugurated, with weekday N Line service in the subway. The Metro service was implemented in phases, and the subway was served only on weekdays until 1982. The K Ingleside Line began using the Metro subway on weekdays on June 11, 1980, the L Taraval and M Ocean View lines on December 17, 1980, and lastly the J Church Line on June 17, 1981. Meanwhile, weekend service on all five lines (J, K, L, M, N) continued to use PCC cars operating on the surface of Market Street through to the Transbay Terminal, and the Muni Metro was closed on weekends. At the end of the service day on Sunday, September 19, 1982, streetcar service on the surface of Market Street was discontinued entirely, the remaining PCC cars taken out of service, and weekend service on the five light rail lines was temporarily converted to buses. Finally, on November 20, 1982, the Muni Metro subway began operating seven days a week. Current Muni metro service has expanded along the waterfront south of the Embarcadero and onto Third Street where it now terminates at the city line.
