Street, Van Ness, Civic Center, Powell Street, Montgomery Street and Embarcadero—were opened in 1980 as part of the Market Street subway. Four stations, Civic Center, Powell Street, Montgomery Street, and Embarcadero, are shared with Bay Area Rapid Transit (BART), with Muni Metro on the upper level and BART on the lower one. Above ground, there are twenty-four 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 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. All subway and surface stations are accessible to people with disabilities. Because the system uses high-floor vehicles, while operating as a streetcar, the vehicles are not accessible to people with disabilities that impact their mobility. A select number of stops, typically located near major intersections, are equipped with ramps or lifts, for people with disabilities. Muni Metro has two rail yards for storage and maintenance: Green Yard or Curtis E. Green Light Rail Center at 425 Geneva Avenue is located adjacent to Balboa Park Station and serves as the outbound terminus for the J Church, K Ingleside, and M Ocean View. The facility has repair facilities, an outdoor storage yard and larger carhouse structure. The facility was renamed for former and late head of Muni 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 maintenance facility with outdoor storage area is located next to Northern Container Terminal and former Army Pier.

Boeing had no experience in making LRVs, and has not made another since. The first cars of the initial 100-car order arrived in San Francisco in 1978; Boston had been running the cars since 1976 and by 1978, MBTA was already returning 35 cars for manufacturing defects.
