The S Shuttle operates as a light rail route within the Muni Metro network of San Francisco, California. Initiated in 2001 under the name S Castro Shuttle to alleviate congestion at Castro station, the service was temporarily halted in 2007 following the introduction of the T Third Street line. In 2013, its route was extended to St. Francis Circle station, but it was later shortened to terminate at West Portal station in 2016. From 2020 through 2024, the shuttle ran continuously as part of a broader Muni Metro system adjustment.

Additionally, the S Shuttle label is applied to trains operating before and after events featuring the San Francisco Giants and Golden State Warriors, facilitating increased transit capacity to Oracle Park and Chase Center.

History

After implementing automatic train control in 1998, Muni doubled subway train frequency from 24 to 48 per hour. However, fleet limitations arose due to aging Boeing LRVs and complications with Breda vehicles. To mitigate overcrowding at Castro station without requiring additional rolling stock, the S Castro Shuttle was launched on April 2, 2001, providing service during weekday peak periods with intervals of 7 to 12 minutes.

When full operation of the T Third Street line began on April 7, 2007, T trains were routed through the subway all the way to Castro station, effectively replacing the S Castro Shuttle. This change also impacted the J Church, N Judah, and various bus services. Despite this, the S Castro Shuttle name remained in use for supplementary service during game days at AT&T Park. Due to significant delays and passenger dissatisfaction caused by these operational adjustments, Muni reinstated the previous routes on June 30, 2007: J, N, and S lines resumed service while T trains were interlined with K Ingleside. The reintroduced shuttle operated with three trains at ten-minute intervals.

On October 4, 2013, Muni trialed an S Shuttle service incorporating three-car trains for the first time since the 1990s. These two- and three-car trains operated between Embarcadero and St. Francis Circle on a limited schedule. Nonetheless, frequent cancellations occurred due to reliability problems and shortages in available vehicles, prioritizing service on branch lines.

Starting November 7, 2016, Muni transitioned to single-car train operations between West Portal station and Embarcadero during weekday morning rush hours, frequently utilizing a more dependable crossover near Taraval and 19th Avenue station. By the year 2019, the S Shuttle was characterized as an infrequent supplementary route.

Due to the impact of the COVID-19 pandemic, rail service was suspended on March 30, 2020 and replaced with buses. Rail operations resumed on August 22 with revised routes aimed at enhancing subway dependability; during this period, S Shuttle frequency increased with two- and three-car trains running every six to nine minutes between West Portal and Embarcadero. However, service reverted back to buses on August 25 due to overhead wire complications and COVID-19 quarantine measures. On May 15, 2021, K/T and N subway lines resumed alongside supplemental S Shuttle operations. The full-time S Shuttle service was ultimately succeeded by continuous L line operation on September 28, 2024.

Beginning in January 2023, following the relocation of T Third Street trains into the Central Subway, shuttle trains marked "S Chase Center" run between and during events held at Chase Center.
