* '''Red Line''': This line begins at Richmond and shares tracks with the Orange Line until reaching downtown Oakland. From here, the line instead crosses into San Francisco, running south to Millbrae before backtracking over the airport wye to terminate at SFO.[[note]]This arrangement - with Yellow Line trains directly running north from SFO while Red Line trains detour to Millbrae first - is for the benefit of airport passengers wanting to connect to Caltrain commuter services at Millbrae so that those passengers don't have to travel up to San Bruno and backtrack. The SFO-Millbrae connection was previously provided by a dedicated shuttle train service (2003-2004 and 2019-2021) and for a time by an extension of the Blue Line (2005-2008).[[/note]] This service runs until 9:00 PM, when the Orange Line replaces it in the East Bay while the Yellow Line replaces it on the San Francisco peninsula.
* '''Blue Line''': The most recent heavy-rail line, it duplicates the Green Line from Daly City to Bay Fair station in San Leandro, then splits off to travel in the median of Interstate 580 through Castro Valley and into Dublin and Pleasanton to the Dublin/Pleasanton station (also one station). BART is currently investigating extending the Dublin/Pleasanton end of the line east to Livermore.

Fare is distance-based, with a few exceptions. A one-way trip will cost anywhere between $1.75 and $10.90. Going through the Transbay Tube, San Mateo County (including Millbrae Station), or entering or exiting at SFO will incur additional charges; as an example, going from San Bruno to Millbrae or vice versa will run you only $2.95, but going from San Bruno to the airport will cost you a particularly brutal ''$7''. And before you ask about unlimited-ride passes, ''no, there aren't any.'' The closest there is is the San Francisco Muni "A" pass, which allows unlimited rides between San Francisco stations. By default, tickets are provided in the form of resuable paper passes, which you insert into the fare gate on entry and exit; exiting a station with exact fare will capture the ticket. Frequent riders are advised to get the wave-and-pay Clipper cards, which are compatible with other Bay Area transit networks and can be pre-loaded with fare and are eligable for bulk tickets, with purchases of $48 and $64 tickets costing only $45 and $60, respectively. Riding on certain Amtrak lines will allow you to purchase $10 tickets for $8. K-12 students whose schools participate in the BART discount program can get a 50% discount on weekday rides, and children, seniors, and disabled passengers can ride at a 62.5% discount. These are the only fare reliefs you will get, short of working for BART. In short, BART is expensive. (Though usually not so much as trying to park a car in downtown San Francisco.)

* '''Yellow Line''': Actually a combination of two separate lines using completely different rolling stock. The segment from Antioch to Pittsburg/Bay Point (also one station), known as '''[=eBART=]''', is light rail using diesel-powered trains running on standard-gauge (4 ft 8½ in/1435 mm) track in the median of California State Route 4, unlike the heavy-rail electric trains running on the broad-gauge (5 ft 6 in/1676 mm) core BART network. There's an existing option to extend [=eBART=] to Brentwood. Yes, the use of slashes is a little confusing. The heavy-rail segment, the second line to open, runs from the Pittsburg/Bay Point station and goes through Oakland, San Francisco, and various smaller cities in northern San Mateo County. At different times in the line's history, it has terminated at San Francisco International Airport (SFO) and Millbrae, with the terminus even differing depending on date and time of day. Currently, as of February 2022, Yellow Line trains terminate at SFO, although evening trains after 9:00 PM continue to Millbrae to replace the Red Line.
* '''Green Line''': A weekday only service running between Berryessa/North San Jose and Daly City. It duplicates the Orange Line between Berryessa and Lake Merritt, and the Blue Line between Bay Fair and Daly City.
* '''Red Line''': This line begins at Richmond and shares tracks with the Orange Line until reaching downtown Oakland. From here, the line instead crosses into San Francisco, running south to Millbrae before backtracking over the airport wye to terminate at SFO.[[note]]This arrangement - with Yellow Line trains directly running north from SFO while Red Line trains detour to Millbrae first - is for the benefit of airport passengers wanting to connect to Caltrain commuter services at Millbrae so that those passengers don't have to travel up to San Bruno and backtrack. The SFO-Millbrae connection was previously provided by a dedicated shuttle train service (2003-2004 and 2019-2021) and at times by an extension of the Blue Line (2005-2008).[[/note]] This service runs until 9:00 PM, when the Orange Line replaces it in the East Bay while the Yellow Line replaces it on the San Francisco peninsula.

* '''Richmond – Berryessa/North San Jose''': The very first BART line, and the only one of the five long-haul lines to not touch San Francisco. The Coliseum/Airport station is connected directly to Oakland International Airport by a peoplemover line with its own listing. The line was extended to the Warm Springs/South Fremont station (yes, that's one station) in 2017. A further two station extension to Berryessa/North San Jose opened in 2020.
* '''Antioch – SFO/Millbrae''': Actually a combination of two separate lines using completely different rolling stock. The segment from Antioch to Pittsburg/Bay Point (also one station), known as '''[=eBART=]''', is light rail using diesel-powered trains running on standard-gauge (4 ft 8½ in/1435 mm) track, unlike the heavy-rail electric trains running on the broad-gauge (5 ft 6 in/1676 mm) core BART network. There's an existing option to extend [=eBART=] to Brentwood. Yes, the use of slashes is a little confusing. The heavy-rail segment, the second line to open, runs from the Pittsburg/Bay Point station and goes through Oakland, San Francisco, and various smaller cities past SF. At different times in the line's history, it terminated at San Francisco International Airport (SFO) and Millbrae, with the terminus even differing depending on date and time of day. As of February 2020, all trains from Pittsburg/Bay Point terminate at SFO at all times. South of SFO, there's...
* '''SFO – Millbrae''': A shuttle service from SFO to the Millbrae station, which also services Caltrain, running to San Jose with limited commuter service all the way to Gilroy. It originally operated from 2003–2004, and reopened in 2019. There are no intermediate stops.
* '''Berryessa/North San Jose – Daly City''': Goes up from Berryessa/North San Jose like the Richmond - Berryessa/North San Jose line, before diverging at Oakland to travel to San Francisco and eventually Daly City.
* '''Richmond – Daly City/Millbrae''': Follows the Richmond - Fremont line before splitting off to cross the Bay and terminate at Daly City or Millbrae. The Millbrae station also services Caltrain, which runs to San Jose (with limited commuter service all the way to Gilroy).
* '''Dublin/Pleasanton – Daly City''': The most recent heavy-rail line, it follows the Fremont - Daly City line going from Daly City to Bay Fair station in San Leandro, then splits off to travel through Castro Valley and into Dublin and Pleasanton to the Dublin/Pleasanton station (also one station). BART is currently investigating extending the Dublin/Pleasanton end of the line east to Livermore.
* '''Coliseum – Oakland International Airport''': The system's newest line, opened in 2014, it uses automated guideway transit technology, with no onboard driver (though BART personnel are on all trains for security purposes). This means that it uses different rolling stock from either the main BART network or [=eBART=]. Like the SFO–Millbrae line, it has no intermediate stations; it runs from the Coliseum station (next to the Oakland Coliseum and Oakland Arena) to Oakland International Airport.

* The Peninsula south of Millbrae receives no BART coverage as well (although that area is served by Caltrain commuter rail, and both BART and Caltrain share the Millbrae station). Until 1996, the only station in San Mateo County was in Daly City, literally a block south of San Francisco city limits.
* Finally, and most infamously, the entire South Bay (including the Bay Area's largest city, San Jose) had no coverage before 2020. That changed when BART extended the Fremont line first to Warm Springs in 2017, and then into the east part of San Jose in 2020 with new stops in Milpitas and Berryessa. These stops also tie BART into the VTA light rail system. There have been plans to extend BART all the way down to Santa Clara, terminating at the Santa Clara Caltrain Station, although lack of funds have prevented this stage of the extension from being seriously put into action just yet.

The reasons for these omissions go back to BART's origins; Santa Clara County declined to join the Bay Area Rapid Transit District at its inception in 1957, instead spending money on a system of expressways. San Mateo County voted to withdraw in December 1961 because it didn't want to lose commerce to San Francisco and felt it was sufficiently served by Southern Pacific's existing Peninsula Commuter Service[[note]]ironically, the county had to scramble to pay for the trains anyway in the late 1970s when SP petitioned to discontinue the line due to mounting losses, turning it into the Caltrain service.[[/note]]. Only a few months after that, Marin County was ''forced'' out due to doubts of its ability to pay for its service and engineering questions about attaching a rail line to the underside of the Golden Gate Bridge. Fortunately, actions have been taken to rectify some of these issues. San Mateo County contributed $200 million to extensions in the East Bay as a "buy-in", and in return between 1996 and 2003 service was extended down to Millbrae and SFO without the county having to officially join BARTD. Construction on a South Bay extension (also funded via a "buy-in" of federal grants and local sales taxes) began in 2012 and was completed in 2018, with the extension reaching out to the Berryessa neighborhood of northeast San Jose. Approval of a second phase of the extension that would continue to downtown San Jose and Santa Clara is currently awaiting additional funds. As for the North Bay...well, [[https://en.wikipedia.org/wiki/Sonoma-Marin_Area_Rail_Transit SMART]] is under development, and there's always the ferry if you just ''have'' to get to [[UsefulNotes/SanFrancisco The City]] without using the Golden Gate Bridge.

Fare is distance-based, with a few exceptions. A one-way trip will cost anywhere between $1.75 and $10.90. Going through the Transbay Tube, San Mateo County (including Millbrae Station), or entering or exiting at SFO will incur additional charges; as an example, going from San Bruno to Millbrae or vice versa (2 stations away) will run you only $2.95, but going from San Bruno to the airport (one less station) will cost you a particularly brutal ''$7''. And before you ask about unlimited-ride passes, ''no, there aren't any.'' The closest there is is the San Francisco Muni "A" pass, which allows unlimited rides between San Francisco stations. By default, tickets are provided in the form of resuable paper passes, which you insert into the fare gate on entry and exit; exiting a station with exact fare will capture the ticket. Frequent riders are advised to get the wave-and-pay Clipper cards, which are compatible with other Bay Area transit networks and can be pre-loaded with fare and are eligable for bulk tickets, with purchases of $48 and $64 tickets costing only $45 and $60, respectively. Riding on certain Amtrak lines will allow you to purchase $10 tickets for $8. K-12 students whose schools participate in the BART discount program can get a 50% discount on weekday rides, and children, seniors, and disabled passengers can ride at a 62.5% discount. These are the only fare reliefs you will get, short of working for BART. In short, BART is expensive. (Though usually not so much as trying to park a car in downtown San Francisco.)

Trains run every 15-20 minutes per line. Obviously, frequencies stack if you're at a station served by multiple lines; in San Francisco, which is served by no less than four lines during peak hours, one train every five minutes is fairly common. Some lines will close early or have no service on Saturdays and especially Sundays, necessitating transfers in order to complete the trip. Some stations are built with transfers in mind, having three or four tracks in use; trains at these stations traveling in particular directions will make prolonged stops in order to accommodate transferring passengers.

Following a series of studies that indicated the decrepit, privately owned [[https://en.wikipedia.org/wiki/Key_System Key System]] of streetcars and buses would be insufficient for the Bay Area's growing postwar population, the Bay Area Rapid Transit District was founded in 1957. Work on the first test track segment between Walnut Creek and Concord began in June 1964 (with the opening ceremonies attended by [[UsefulNotes/LyndonJohnson LBJ]]), construction of the core system (including the Transbay Tube, miles of track under and through downtown San Francisco and several other cities, and a tunnel through the Berkeley Hills) took place over the next eight years, and the system was officially launched in 1972. BART initially opened up for service with one line between the [=MacArthur=] station in UsefulNotes/{{Oakland}} and Fremont Station in, well, Fremont. Since then, BART has expanded to cover more of the East Bay, as well as the San Francisco side of the SF Bay via the famous Transbay Tube (which opened in 1974 and runs under the Bay parallel to the SF-Oakland Bay Bridge), parallelling the Interstate 80, Interstate 680 and Interstate 880 commute routes.

The Coliseum/Airport station is connected directly to Oakland International Airport by a peoplemover line with its own listing.

Fare is only charged when you exit a station, so transfers come at no extra cost. However, because your fare is not charged until you exit a station, this can result in situations where the fare gates bar you from exiting because you don't have enough fare to leave. Previously, Clipper users could exit the station with a negative fare of up to -$11.25 just fine, but in September 2013, exiting with a negative fare is no longer allowed. For this reason, there are Addfare machines that will allow you to add just enough fare to get out of the system. To prevent people from simply boarding a train, travelling all over the network, and then coming back, [[NoFairCheating a $5.25 excursion fee is applied for exiting the same station you last entered]].

Trains run every 15-20 minutes per line. Obviously, frequencies stack if you're at a station served by multiple lines; in San Francisco, which is served by no less than four lines during peak hours, one train every five minutes is fairly common.

Some stations are built with transfers in mind, having three or four tracks in use; trains at these stations traveling in particular directions will make prolonged stops in order to accomodate transferring passengers.

In 2013, a variety of disputes led to BART workers going on several strikes, with each strike completely shutting down BART service and dealing a huge blow to the Bay Area commute. On the other hand, after the 1989 Loma Prieta earthquake caused a partial collapse of the Bay Bridge, BART continued to run, as it had suffered no damage (having been designed with earthquakes in mind), allowing East Bay commuters to get to their jobs without having to drive. It is still considered BART's finest hour.

BART's subways are some of the few in the United States to offer cellphone coverage, so feel free to check your Facebook, send text messages, or [[TVTropesWillRuinYourLife browse TV Tropes]] while riding. [[DamnYouMuscleMemory Do not expect this same amenity on other subway networks.]] Notoriously, in 2011, BART temporarily shut down cellphone service to hamper protests following the shooting of Charles Hill, which was not particularly well-received amongst passengers and especially Tropers/{{Anonymous}}.

BART has its own branch of the police. BART Police's reputation has not been particularly positive, especially after the shooting of Oscar Grant in 2009 ([[Administrivia/RuleOfCautiousEditingJudgment the details and discussion of which are best left off of this page]]) and the aforementioned Charles Hill. In early 2014, for the first time in the system's history a BART police officer was killed in the line of duty when he was accidentally shot by a fellow officer while serving a search warrant.
