Infrastructure
The 115 -kilometer network is served by six lines which all run through a central tunnel. This tunnel has nine stations and consisting of two sections. The first, called the Twin Peaks Tunnel was opened already on 3 February 1918 and is traversed by four of the six lines. He scored at the opening of the longest streetcar tunnel in the world. The second part is the Market Street Subway, a common structure with the BART, which is traversed by all lines. This tunnel was put into operation in 1973 for BART and 1980, a level above the Muni Metro. Another tunnel, called the Central Subway, crossing the Market Street is currently under construction.
