Editing Bay Area Rapid Transit (section)

== Services ==
BART serves large portions of its three member counties – [[San Francisco]], [[Alameda County, California|Alameda]], and [[Contra Costa County, California|Contra Costa]] – as well as smaller portions of [[San Mateo County, California|San Mateo County]] and [[Santa Clara County, California|Santa Clara]] counties. The system has [[List of Bay Area Rapid Transit stations|50 stations]]: 22 in Alameda County, 12 in Contra Costa County, 8 in San Francisco, 6 in San Mateo County, and 2 in Santa Clara County. BART operates five named heavy rail services plus one separate automated guideway line. All of the heavy rail services run through [[Oakland, California|Oakland]], and all but the Orange Line cross the bay through the [[Transbay Tube]] to San Francisco. All five services run every day until 9 pm; only three services operate evenings after 9 pm. All stations are served during all service hours.<ref name="feb2022changes">{{Cite press release |title=BART schedule change begins 2/14/22, extending service to midnight on Sundays |date=January 10, 2022 |publisher=Bay Area Rapid Transit District |url=https://www.bart.gov/news/articles/2022/news20220110-0}}</ref> The [[eBART|eastern segment]] of the {{lnl|BART|Yellow}} (between Antioch and the transfer platform east of Pittsburg/Bay Point) uses different rolling stock and is separated from the rest of the line.<ref name=systemmap>{{cite web |url=https://www.bart.gov/sites/default/files/docs/system-map-detailed-version.pdf |date=2022 |title=Every day until 9pm: 5-Line Service |publisher=Bay Area Rapid Transit District}}</ref>

=== Hours and frequencies ===
BART has elements of both traditional [[rapid transit]] (high-frequency urban service with close station spacing) and [[commuter rail]]/[[regional rail]] (lower-frequency suburban service with wider station spacing). Trains on each primary service run every 20 minutes, except the busy Yellow Line, which operates every 10 minutes on weekdays.<ref>{{cite news |url=https://www.sfchronicle.com/bayarea/article/bart-announces-fall-schedule-changes-tradeoffs-17923872.php |title=This BART line's trains will run more frequently under new schedule changes |first=Ricardo |last=Cano |date=April 27, 2023 |newspaper=San Francisco Chronicle |access-date=June 5, 2023}}</ref> Segments served by multiple lines have higher frequencies, the busiest of which is the section between Daly City and West Oakland, which has around 15 trains per hour (one train about every four minutes), per direction at peak hours.<ref name="BART 2023 Schedule" /> The [[Oakland Airport Connector]] runs "on demand", typically on headways of 10 minutes or less.<ref name="schedulepdfs" />

[[Cross-platform interchange|Timed cross-platform transfers]] are available between the Orange Line, which operates only in the East Bay, and the Yellow Line, which operates through the Transbay Tube to the San Francisco Peninsula. This service complements the Red Line during daytime hours and replaces that line when it stops operating after 9pm.<ref name="BART 2023 Schedule" />

The first inbound trains leave outer terminals around 5:00 am on weekdays, 6:00 am on Saturdays, and 8:00 am on Sundays and most holidays. The last trains of the service day leave their terminals around midnight; the final Yellow and Orange Line trains in both directions meet at [[MacArthur station (BART)|MacArthur station]], and the final Orange and Blue Line trains in the southbound direction meet at [[Bay Fair station]], for guaranteed transfers.

=== Bus services ===
Two different bus networks are operated by regional transit agencies as a [[rail replacement bus service]] when BART is not operating due to regularly scheduled maintenance during the overnight hours.

The [[All Nighter (night bus service)|''All Nighter'']] network provides basic bus service to San Francisco, the East Bay, and Peninsula, replicating rail transit services in those regions, including BART, Caltrain, and Muni Metro. All Nighter buses serve most BART stations (directly or within several blocks), replicating 3-Line late night BART service with abbreviated routes:<ref>{{Cite web |date=May 16, 2024 |title=Transit Information: Late Night Bus Services |url=https://511.org/media/604/show |publisher=Metropolitan Transportation Commission}}</ref>
* Buses replicating Yellow Line service terminate at [[Rockridge station|Rockridge]] (stations east of Rockridge to the regular terminus at [[Antioch station (BART)|Antioch]] are not served)
* Buses replicating Blue Line service terminate at [[Bay Fair station|Bay Fair]] (stations east to [[Dublin/Pleasanton station|Dublin/Pleasanton]] are not served)
* Buses replicating Orange Line service terminate at [[Fremont station (BART)|Fremont]] (stations south to [[Berryessa/North San José station|Berryessa/North San José]] are not served)
The All Nighter-branded bus service started in 2006,<ref>{{cite press release |url=https://www.bart.gov/news/articles/2006/news20060519 |title=Now transit stays up as late as you! Catch the "All Nighter" bus service |date=May 19, 2006 |publisher=San Francisco Bay Area Rapid Transit District |access-date=13 March 2025}}</ref> although late night bus service had been provided as an alternative to BART prior to then.

The ''{{vanchor|Early Bird Express}}'' network is another bus alternative which provides service to major BART stations in the early morning between 3:50 am and 5:30 am.<ref name=BART-EBE>{{cite web |url=https://www.bart.gov/schedules/early-bird-express |title=Early Bird Express |publisher=San Francisco Bay Area Rapid Transit District |access-date=13 March 2025}}</ref> Early Bird Express buses are operated by local transit agencies, including [[AC Transit]], [[Golden Gate Transit]], [[San Francisco Municipal Railway|Muni]], and [[SamTrans]], running between a limited number of major BART stations on San Francisco/Peninsula and Transbay routes which all meet at the [[Salesforce Transit Center]]. Early Bird Express routes are identified by three-digit route numbers starting with 7xx.<ref name=BART-EBE/> {{as of|2024|08}}, there are six Early Bird Express routes, replicating 3-Line service:<ref name=BART-EBE/>
* Yellow Line bus substitute operating to and from Millbrae (Peninsula)
* Blue Line bus operating to and from Daly City (San Francisco)
* Yellow Line buses operating from Pittsburg/Bay Point and Pleasant Hill (Transbay)
* Blue Line bus operating from Dublin/Pleasanton (Transbay)
* Orange Line bus operating from El Cerrito del Norte (Transbay)
The original Early Bird Express network was introduced in February 2019 when the start of rail service was shifted from 4&nbsp;a.m. to 5&nbsp;a.m. to accommodate seismic upgrades in the [[Transbay Tube]];<ref>{{cite press release |url=https://www.bart.gov/news/articles/2018/news20181105-1 |title=BART to open at 5am starting 2-11-2019 with alternative bus service provided |date=November 5, 2018 |publisher=San Francisco Bay Area Rapid Transit District |access-date=March 24, 2025}}</ref> at its debut, it featured fifteen routes,<ref>{{cite web |url=https://www.bart.gov/sites/default/files/docs/EBflyer_FINAL%201-30-19.pdf |title=Early Bird Express (flyer) |date=January 30, 2019 |publisher=San Francisco Bay Area Rapid Transit District |access-date=March 24, 2025}}</ref><ref>{{Cite web |year=2019 |title=Early Bird Express |url=https://www.bart.gov/sites/default/files/docs/EBflyer_v12.pdf |publisher=San Francisco Bay Area Rapid Transit District}}</ref> but some were eliminated later that year due to low ridership.<ref>{{Cite web |date=June 4, 2019 |title=EBX June 2019 Service Improvements |url=https://www.bart.gov/sites/default/files/docs/EBX%20June%202019%20Service%20Changesv3-For%20Web.pdf |publisher=San Francisco Bay Area Rapid Transit District |page=12}}</ref><ref>{{Cite press release |title=Early Bird Express service changes coming 12/16 |date=December 10, 2019 |publisher=San Francisco Bay Area Rapid Transit District |url=https://www.bart.gov/news/articles/2019/news20191210}}</ref> Additional routes were eliminated in 2024, including an inbound bus from Fremont replicating Orange Line service.<ref>{{cite press release |url=https://www.bart.gov/news/articles/2024/news20240313-0 |title=BART to reduce some Early Bird Express Bus trips starting August 12, 2024 |date=August 4, 2024 |publisher=San Francisco Bay Area Rapid Transit District |access-date=13 March 2025}}</ref>

Historically, BART operated ''{{vanchor|BART Express}}'' bus service between 1974 and 1997, extending transit coverage to central and eastern Alameda and Contra Costa counties; these routes were discontinued following the completion of rail line extensions starting in the late 1990s. BART Express was operated for BART under contracts to AC Transit (1974–1989) and Laidlaw (1989–1997).<ref>{{cite web |url=https://bartcars.weebly.com/bart-express.html |title=BART Express |website=BARTchives |access-date=13 March 2025}}</ref> Since then, some services similar to the legacy BART Express routes which were not replaced by rail service have been taken over by local bus operators, including WestCAT<ref>{{cite report |url=https://www.westcat.org/Content/Pdf/Short-Range-Transit-Plan-Public-FINAL.pdf |title=Short-Range Transit Plan |date=2016 |publisher=Western Contra Costa Transit Authority |access-date=13 March 2025 |quote=A contractor employed directly by BART, using the marketing name of BART Express, formerly operated express service to BART from the WCCTA service area. In July 1998, WCCTA assumed operation of this service and has continually restructured service to enhance performance. The express J (JL/JR), JX, and JPX routes have taken over this role.}}</ref>{{rp|6}} and Tri Delta Transit.<ref>{{cite report |url=https://trideltatransit.com/wp-content/uploads/2024/05/ECCTA-2020-29-SRTP.pdf |title=Short Range Transit Plan |date=2020 |publisher=Eastern Contra Costa Transit Authority |access-date=13 March 2025 |quote=In 1997, Tri Delta Transit assumed responsibility for BART Express bus service between Pittsburg/Bay Point BART and Brentwood via the Highway 4 corridor.}}</ref>{{rp|5}}

To accommodate those with conditions and disabilities that prevent from boarding a train, BART has entered a joint venture with AC Transit to establish [[East Bay Paratransit]] to provide [[paratransit]] bus services. <ref>{{cite web |title=Who Provides East Bay Paratransit |url=https://www.eastbayparatransit.org/who-provides-east-bay-paratransit.htm |website=www.eastbayparatransit.org}}</ref>

=== Connecting services ===
[[File:AC Transit buses and San Leandro station, April 2018.JPG|thumb|right|AC Transit buses at San Leandro station]]
Intermodal connections to local, regional, and intercity transit – including bus, [[light rail]], [[commuter rail]], and [[intercity rail]] – are available across the BART system. Three [[Amtrak]] intercity rail services – the ''[[California Zephyr]]'', ''[[Capitol Corridor]]'', and ''[[San Joaquins]]'' – stop at [[Richmond station (California)|Richmond station]]; the ''Capitol Corridor'' also stops at [[Oakland Coliseum station]].<!-- Oakland – Jack London Square station and Emeryville station are not located near BART stations. --><ref name="systemmap" /> Transfer between BART and the [[Caltrain]] commuter rail service is available at [[Millbrae station]].<ref name=systemmap />

BART and most lines of San Francisco's [[Muni Metro]] light rail system share four stations ([[Embarcadero station|Embarcadero]], [[Montgomery Street station|Montgomery Street]], [[Powell Street station|Powell Street]], and [[Civic Center/UN Plaza station|Civic Center/UN Plaza]]) in the [[Market Street subway]]; connections are also available to three lines at [[Balboa Park station]] and one line at [[Glen Park station]]. A tunnel at the Powell Street station connects to the [[Union Square/Market Street station]] on the Muni Metro [[T Third Street]] line. In the South Bay, [[Milpitas station]] provides a connection to the [[Orange Line (VTA)|Orange Line]] of [[VTA light rail]].<ref name=systemmap />

BART is served by bus connections from regional and local transit agencies at all stations, most of which have dedicated off-street bus transfer areas. Many connecting routes (particularly in suburban areas) serve primarily as feeder routes to BART. Larger bus systems connecting to BART include [[San Francisco Municipal Railway|Muni]] in San Francisco, [[AC Transit]] in the East Bay, [[SamTrans]] in San Mateo County, [[County Connection]] and [[Tri Delta Transit]] in eastern Contra Costa County, [[WestCAT]] in western Contra Costa County, [[WHEELS (California)|WHEELS]] in the Tri-Valley, [[Santa Clara Valley Transportation Authority|VTA]] in the Santa Clara Valley, and [[Golden Gate Transit]]. Smaller systems include [[Emery Go-Round]] in Emeryville, [[Commute.org]] on the Peninsula, [[San Leandro LINKS]], [[Dumbarton Express]], and [[Union City Transit]]. The [[Salesforce Transit Center]] regional bus hub is located one block from Embarcadero and Montgomery stations.<ref name="tcmaps">{{cite web |title=Transit Center Maps and Information |url=https://www.actransit.org/transit-center-maps-and-information |publisher=Alameda Contra Costa Transit District}}</ref>

Several transit agencies offer limited commuter-oriented bus service from more distant cities to outlying BART stations; these include [[VINE (Napa County)|VINE]] from Napa County, [[Solano Express]] from Solano County, [[Rio Vista Delta Breeze]], [[Stanislaus Regional Transit Authority]] from Stanislaus County, and [[San Joaquin Regional Transit District|San Joaquin RTD]] from Stockton. Many BART stations are also served by privately run employer and hospital shuttles, and privately run intercity buses stop at several stations.<ref name=tcmaps />

=== Airport connections ===
{{Main|Oakland International Airport station|San Francisco International Airport station}}
BART also runs directly to two of the three major Bay Area airports ([[San Francisco International Airport]] and [[Oakland International Airport]]) with service to [[San Jose International Airport]] provided by a [[List of Santa Clara VTA bus routes#60|VTA bus route]] available at [[Milpitas station]].<ref name=tcmaps /><ref name=systemmap />
