The service began in 2001 as the S Castro Shuttle, an effort to reduce crowding at Castro station. It was briefly discontinued in 2007 when the T Third Street line was opened. Service was extended to St. Francis Circle station in 2013, but cut back to West Portal station in 2016. The service runs during rush hours with one-car or two-car trains depending on the availability of rolling stock. The designation of S Shuttle is also given to trains at other hours and locations, including service run before and after San Francisco Giants games to provide additional capacity to AT&T Park, as well as unscheduled trains operated anywhere in the system. HistoryAfter the installation of automatic train control in 1998, the maximum Muni Metro frequency through the Market Street Subway doubled from 24 trains per hour to 48. Muni needed to increase capacity to accommodate growing ridership, but the aging Boeing LRV fleet and issues with the new Breda fleet left too few vehicles to run additional service on the branch lines. Instead, Muni introduced the S Castro Shuttle, which could relieve crowding at busy Castro station while using only a small amount of rolling stock. The service began on April 2, 2001, running only at rush hour on weekdays, with headways between 7 and 12 minutes.[1] A variety of service changes took place with the introduction of full service on the T Third Street line on April 7, 2007. The new line was routed through the subway to Castro station, replacing the S Castro Shuttle; changes were also made to the J Church, N Judah, and several bus lines.[2] (The S Castro Shuttle designation continued to be used for extra service to AT&T Park on San Francisco Giants game days.) The changes were unpopular with the public; the Muni Metro changes caused severe delays in the Market Street Subway, and forced many riders to transfer to reach the Caltrain station when they previously did not. On June 30, 2007, Muni reversed several of the changes. The J, N, and S were restored to their previous routes, while the T was interlined with the K Ingleside line.[3] The revived shuttle ran on 10-minute headways using three trains.[4][5] On October 4, 2013, Muni began a pilot of S Shuttle service, which included the first three-car train on Muni Metro since the 1990s.[6] The three-car train and a two-car train ran between Embarcadero and St. Francis Circle station with only six morning round trips and one evening round trip; the last morning trips ran through to 23rd Street on their way to the Muni Metro East facility.[7] However, the three-car set proved unreliable, and perennial rolling stock shortages caused the shuttles to be frequently cancelled in favor of branch line service.[8] On November 7, 2016, Muni changed the service to a pair of single-car trains running between West Portal station and Embarcadero. The revamped service, which was modeled after similar Hillway shuttles on the N Judah line, runs during weekday morning rush hours.[9] Although it nominally switches back at West Portal, service often instead uses a more reliable crossover at Taraval and 19th Avenue station.
