The '''S Shuttle''' is a [[light rail]] service on the [[Muni Metro]] system in [[San Francisco, California]]. 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. From 2020 to 2024, the shuttle ran as a full-time service as part of a reconfiguration of Muni Metro service.<ref name="aug22" />

The designation of S Shuttle is also given to trains at other hours and locations, most commonly to those which run service before and after [[San Francisco Giants]] and [[Golden State Warriors]] games to provide additional capacity to [[Oracle Park]] and [[Chase Center]] respectively.

==History==
[[File:S Ballpark Shuttle.jpg|thumb|left|S Castro Shuttle rollsign on a game-day extra train in 2007.]]
[[File:S Shuttle crossing over near West Portal, June 2017.JPG|thumb|left|An S Shuttle train crossing over near West Portal station in 2017.]]
After the [[Muni Metro#Muni meltdown|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.<ref>{{cite book |url=http://tjpa.org/uploads/2009/11/FEIS_Ch3.pdf |title=Transbay Terminal / Caltrain Downtown Extension / Redevelopment Project EIS/EIR  |chapter=Chapter 3: Transportation Analysis |pages=3–10 |date=March 2004 |publisher=Federal Transit Administration}}</ref>

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.<ref>{{cite web |archive-url=https://web.archive.org/web/20070714000010/http://www.sfmta.com/cms/mroutes/documents/T3-Manual_v6na.pdf |url=http://www.sfmta.com/cms/mroutes/documents/T3-Manual_v6na.pdf |archive-date=July 14, 2007 |title=Discover the T-Third |year=2007 |publisher=San Francisco Municipal Transportation Agency |page=6}}</ref> (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 [[San Francisco 4th and King Street station|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.<ref>{{cite press release |url=http://www.sfmuni.com/cms/malerts/ServiceChangesEffectiveJune302007.htm |archive-date=June 24, 2007 |archive-url=https://web.archive.org/web/20070624222728/http://www.sfmuni.com/cms/malerts/ServiceChangesEffectiveJune302007.htm |title=SFMTA announces service changes effective June 30, 2007 |publisher=San Francisco Transportation Agency |date=June 30, 2007}}</ref> The revived shuttle ran on 10-minute headways using three trains.<ref name=seis>{{cite book |url=https://www.sfmta.com/sites/default/files/reports/2017/Central_Subway_Final_SEISSEIR_Volume_I_Part1.pdf |pages=3–9 |title=Central Subway Final Supplemental Environmental Impact Statement / Supplemental Environmental Impact Report |chapter=Chapter 3: Transportation Analysis |date=September 2008 |publisher=Federal Transit Administration |volume=1}}</ref><ref>{{cite web |archive-url=https://web.archive.org/web/20120924090929/http://transit.511.org/accessible/schedules/detail.aspx?cid=SF&rte=43875&dir=IB&day=6098&dayid=6098 |archive-date=September 24, 2012 |url=http://transit.511.org/accessible/schedules/detail.aspx?cid=SF&rte=43875&dir=IB&day=6098&dayid=6098 |title=S Inbound Weekday |publisher=511 SF Bay}}</ref>

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.<ref>{{cite news |last1=Kwong |first1=Jessica |title=Muni's three-train shuttle service a hit with riders |url=http://archives.sfexaminer.com/sanfrancisco/munis-three-train-shuttle-service-a-hit-with-riders/Content?oid=2602326 |newspaper=The San Francisco Examiner|date=October 11, 2013}}</ref> 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 station (California)|23rd Street]] on their way to the Muni Metro East facility.<ref>{{cite web |archive-url=https://web.archive.org/web/20140427092120/http://transit.511.org/accessible/schedules/detail.aspx?cid=SF&rte=43875&dir=IB&day=6098&dayid=6098 |archive-date=April 27, 2014 |url=http://transit.511.org/accessible/schedules/detail.aspx?cid=SF&rte=43875&dir=IB&day=6098&dayid=6098 |title=S Inbound Weekday |publisher=511 SF Bay}}</ref> 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.<ref>{{Cite press release |url=https://www.sfmta.com/about-sfmta/blog/roomier-trains-have-muni-subway-shuttles-helped-your-commute |title=Roomier Trains: Have Muni Subway Shuttles Helped Your Commute? |publisher=San Francisco Municipal Transportation Agency|date=November 7, 2016 |language=en}}</ref>

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 [[Carl and Hillway station|Hillway shuttles]] on the [[N Judah]] line, ran during weekday morning rush hours.<ref>{{Cite press release |url=https://www.sfmta.com/about-sfmta/blog/more-muni-subway-service-coming-roomier-metro-ride |title=More Muni Subway Service Coming for a Roomier Metro Ride |publisher=San Francisco Municipal Transportation Agency |date=October 20, 2016}}</ref> Although it nominally switched back at West Portal, service often instead used a more reliable crossover at [[Taraval and 19th Avenue station]]. By 2019, the SFMTA described the S Shuttle as an irregular route meant to supplement other Muni services.<ref>{{cite web |title=S Shuttle |date=4 January 2019 |url=https://www.sfmta.com/routes/s-shuttle |publisher=San Francisco Municipal Transportation Agency |access-date=July 10, 2019}}</ref>

On March 30, 2020, Muni Metro service was replaced with buses due to the [[COVID-19 pandemic]].<ref>{{cite press release |url=https://www.sfmta.com/blog/starting-march-30-new-muni-service-changes |title=Starting March 30: New Muni Service Changes |date=March 26, 2020 |first=Amy |last=Fowler |publisher=San Francisco Municipal Transportation Agency}}</ref> Rail service returned on August 22, with the routes reconfigured to improve reliability in the subway. S Shuttle service frequency was increased, as three other lines no longer entered the subway; two- and three-car trains operated between West Portal and Embarcadero on 6–9 minute headways.<ref name=aug22>{{cite press release |url=https://www.sfmta.com/blog/major-muni-service-expansion-august-22 |title=Major Muni Service Expansion August 22 |date=August 18, 2020 |first=Mariana |last=Maguire |publisher=San Francisco Municipal Transportation Agency}}</ref> Rail service was re-replaced with buses on August 25 due to issues with malfunctioning [[overhead wire]] [[Line splice|splices]] and the need to quarantine control center staff after a COVID-19 case.<ref>{{cite press release |url=https://www.sfmta.com/travel-updates/bus-substitution-all-rail-lines |date=August 25, 2020 |title=Bus Substitution for All Rail Lines |publisher=San Francisco Municipal Transportation Agency}}</ref> K/T and N subway service resumed on May 15, 2021, along with supplemental S Shuttle service.<ref>{{cite press release |url=https://www.sfmta.com/blog/welcome-back-westside-k-ingleside-trains |title=Welcome Back to the Westside, K Ingleside Trains! |date=April 16, 2021 |publisher=San Francisco Municipal Transportation Agency}}</ref><ref>{{cite web |archiveurl=https://web.archive.org/web/20210715175640/https://www.sfmta.com/projects/rail-recovery |archivedate=July 15, 2021 |url=https://www.sfmta.com/projects/rail-recovery |title=Rail Recovery |date=7 July 2020 |publisher=San Francisco Municipal Transportation Agency}}</ref> Full-time S shuttle service was replaced by full-time L service on September 28, 2024.

Since T Third Street service moved to the [[Central Subway (San Francisco)|Central Subway]] in January 2023, shuttle trains signed "S Chase Center" operate between {{munis|Chinatown}} and {{munis|UCSF/Chase Center}} for events at Chase Center.<ref>{{cite press release |url=https://www.sfmta.com/blog/new-t-third-route-central-subway-starting-january-7 |title=New T Third Route in Central Subway Starting January 7 |date=December 13, 2022 |first=Mariana |last=Maguire |publisher=San Francisco Municipal Transportation Agency}}</ref>
