The K Ingleside is a Muni Metro line in San Francisco, California, mainly serving the West Portal and Ingleside neighborhoods. The original K Ingleside streetcar line opened in 1918. It was one of San Francisco's streetcar lines in the early 20th century, and was partially converted to modern light rail operation in 1979–80 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 K Ingleside remained a streetcar line due to its use of the Twin Peaks Tunnel.
The outer end of the line was originally a stub at the intersection of Brighton and Grafton. In the 1940s an additional branch of the line was built down Onondaga Street to Mission Street. In the 1950s, this was shortened to the Phelan loop at Ocean and Lee. On April 23, 1979, the line was shortened to Balboa Park BART Station. Initially, only supplemental trips running from West Portal and using newly-in-service Boeing Light Rail Vehicles (LRVs) served the new extension, weekdays only, and most K-line service continued to use PCC streetcars running from downtown to Phelan Loop. The LRV shuttle service ended in February 1980, and PCC-operated service was extended to Balboa Park, but lasted only four months before the weekday service was replaced by a temporary K-L crosstown route using LRVs (and weekend service cut back to Phelan Loop). Additional changes to the service configuration followed until finally on December 17, 1980, the K line became operated as a through service from Embarcadero Station to Balboa Park, using LRVs, on weekdays only. Weekend service continued to use PCC cars until September 1982.
The line runs from the Embarcadero Station downtown to the Geneva Avenue and San Jose Avenue in the Balboa Park neighborhood, near City College of San Francisco. 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 L Taraval and M Ocean View lines, emerging at West Portal Station. From there, it follows West Portal Avenue to Saint Francis Circle, where it then runs on its own right-of-way in the middle of Junipero Serra Boulevard to Ocean Avenue. The K then follows Ocean Avenue until it reaches Balboa Park Station, where it circles around the Metro yard at San Jose and Geneva Avenue, with the actual terminal stop alongside the station.
Following service changes on June 30, 2007, the K Ingleside and the T Third Street lines were spliced together inside the Market Street Subway tunnel, though keeping their respective line designations, resulting in an upside-down horseshoe-shaped route from Balboa Park to Bayshore and Sunnydale. At West Portal Station, inbound K trains heading towards downtown change their signs to the T line; conversely, at Embarcadero Station, T trains heading into downtown change signs to the K line. The trains show the ultimate destination of the spliced lines rather than the intermediate "terminus" of the individual line.
The K Ingleside line stops at large stations for the downtown section of the line and at smaller stops on the rest of the line. Most of the smaller stops are nothing more than concrete "islands" in the middle of the street next to the tracks. Some of these "island" stops provide access for wheelchairs. Muni bus routes provide service to all stations and other systems with access to the stations are noted.
The K Ingleside 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 10 minutes during the day, and 12 to 15 minutes at night. Late night service is provided by the 91 Owl diesel bus line on West Portal and Ocean Avenue, and by the L-Owl diesel bus line from West Portal Station to Market Street and Steuart Street, near Embarcadero Station. There is also a K-Owl diesel bus line that runs from Market Street and Steuart Street to Balboa Park. This line makes a limited number of trips between the times owl service stops and the underground subway stations open.
