M Ocean View
The M Ocean View is a Muni Metro light rail line in San Francisco, California. It was one of San Francisco's streetcar lines in the early 20th century, and was converted to modern light-rail operation with the creation of the Muni Metro system in the late 1970s. While many streetcar lines were converted to buses after World War II, the M Ocean View remained a streetcar line due to its use of the Twin Peaks Tunnel.
The outer end of the line was originally at the intersection of Broad Street and Plymouth Avenue, where streetcars used a wye to turn around, but on August 30, 1980, the line was extended to Balboa Park BART station. Eureka Station in the Twin Peaks Tunnel was originally a stop on the M line, but the station was closed in 1972 and replaced, 10 years later, by Castro Street Station when the Metro system opened.
The line runs from the Embarcadero Station in the Financial District to Geneva Avenue and San Jose Avenue near City College of San Francisco in the Balboa Park neighborhood. The downtown portion of the line runs through the Market Street Subway, which it shares with the four other Muni Metro lines. It continues through the much older Twin Peaks Tunnel, along with the K Ingleside and L Taraval lines, emerging at West Portal Station. From there, it follows West Portal Avenue to the Saint Francis Circle, where it then takes its own right-of-way to 19th Avenue. The portion of the line on 19th Avenue between where it joins 19th near Eucalyptus Drive and Junipero Serra Boulevard is a right-of-way separated from the street. This section has two stations with high-platforms, one at the Stonestown Galleria on Winston Drive and the other at San Francisco State University on Holloway Avenue. It continues on 19th Avenue past Junipero Serra to Randolph Street. At the end of Randolph, the M uses Orizaba Avenue to get to Broad Street and takes that to San Jose Avenue. The rest of the line follows San Jose Avenue to Geneva Avenue, where the line loops around the Metro yard there on the opposite corner Balboa Park Station.
The M Ocean View line stops at large stations for the downtown section of the route and on 19th Avenue and at smaller stops on the rest of the line. Most of the smaller stops are nothing more than a sign on the side of the street designating a stop and a few others are concrete 'islands' in the middle of the street next to the tracks that provide access for wheelchairs. Muni bus routes provide service to all stations and other systems with access to the stations are noted.
The M Ocean View begins service at 5 a.m. weekdays, 6 a.m. Saturdays and 8 a.m. Sundays, with the end of service occurring around 12:30 a.m. each night. It operates a headway of 9 to 12 minutes during the day, and 15 to 20 minutes at night. There is no late night service along the entire M line, however part of the L-Owl diesel bus line runs from West Portal Station to Market Street and Steuart Street, near Embarcadero Station, and the 91 Owl line operates on 19th Avenue. On Sunday mornings only, there is a M-Owl diesel bus line that runs on surface streets from Market Street and Steuart Street to Balboa Park between the times owl service stops and the underground subway stations open.
St. Francis Circle Project
In May 2010, the San Francisco MTA began a major project to reconstruct and replace the rail junction at St. Francis Circle. The MTA decided to discontinue all M Ocean View rail service for the duration of the project. Passengers were required to take K Ingleside trains (which temporarily terminated at 14th Avenue) or L Taraval trains and transfer to temporary shuttle bus service at West Portal.
M rail service was restored on Sept. 4, 2010.
