System details

BART comprises 104 miles (167 km) of track and 43 stations. The system uses a 5 ft 6 in (1,676 mm) broad rail gauge, as opposed to the 4 ft 8+1⁄2 in (1,435 mm) standard gauge predominantly found in the United States. Trains can achieve a centrally-controlled maximum speed of 80 mph (130 km/h) and provide a systemwide average speed of 33 mph (53 km/h) with twenty-second station dwell times. Trains operate at a minimum length of three cars per California Public Utilities Commission guidelines to a maximum length of 10 cars, spanning the entire 700 feet (213 m) length of a platform. At its maximum length of 710 feet (216 m), BART has the longest train length of any metro system in the United States. The system also features car widths of 10.5 feet (3.2 m), a maximum gradient of 4%, and a minimum curve radius of 394 feet (120 m).

Notice the walkway on the left side of the trackway in the distance, which is the emergency walkway for the aerial trackway leading into the Daly City station – again, the third rail positioned opposite of this walkway.

Electric current is delivered to the trains over a third rail, the position of which alternates relative to the context of the train. Inside stations, the third rail is always on the side furthest away from the passenger platforms. This design feature eliminates the danger of a passenger either falling directly on the third rail, or stepping onto it to climb back to the platform should they fall off. On ground-level trackways, the third rail alternates from one side of the track to the other, providing breaks in the third rail to allow for emergency evacuations across trackways.

Underground tunnels, aerial structures and the Transbay Tube have evacuation walkways and passageways to allow for train evacuation without exposing passengers to easy, inadvertent contact with the third rail, which is located as far away from these walkways as possible. The voltage on the third rail is 1000 V DC, so there are notices throughout the system warning passengers of its danger. In addition, BART posts notices inside each train car warning of the third rail and the four paddle-like rail contact shoes protruding from the underside of each car by the rail wheel trucks.

Many of the original system 1970s era BART stations, especially the aerial stations, feature simplistic Brutalist architecture.

Hours of operation and frequencies

The BART system consists of five lines, but most of the network consists of more than one line on the same track. Trains on each line historically ran every fifteen minutes on weekdays and twenty minutes during the evenings, weekends and holidays; however, since a given station might be served by as many as four lines, it could have service as frequently as every three to four minutes.

As of January 1, 2008, service on every line is at 15-minute intervals at all times except for Saturdays between 6:00 a.m. and 7:00 p.m., when service is at 20-minute intervals. Also, as of January 1, 2008, BART service begins around 4:00 a.m. on weekdays, 6:00 a.m. on Saturdays, and 8:00 a.m. on Sundays. Service ends every day near midnight with station closings timed to the last train at station. Two of the five lines, the Millbrae—Richmond and SF/Daly City—Fremont lines, do not have night (after 7 p.m.) or Sunday service, but all stations remain accessible by transfer from the other lines. All-Nighter Network service is available when BART is closed. All but six BART stations are served (as well as eight Caltrain stations). BART tickets are not accepted on these buses, and each of the four bus systems charge their own fare, which can be up to $ 3.50; a four-system ride can cost as much as $ 9.50 as of 2007.

Current lines

BART Routes:

  Richmond – Millbrae

  Fremont – Daly City

  Richmond – Fremont

  Pittsburg/Bay Point – SFO

  Dublin/Pleasanton – Millbrae

Unlike most other rapid transit and rail systems around the world, BART lines are generally not referred to by shorthand designations. Although the lines have been colored consistently on BART system maps for more than a decade, they are only occasionally referred to officially by color names, and only rarely referred to in this way by members of the public (e.g., the “Red Line”). Each line is generally identified on maps and schedules by the names of its termini (e.g., “Richmond – Millbrae Line”). Although terminal stations have seldom changed over the years, referring to routes by termini has contributed to rider confusion, as each incremental onward extension changes the line name.

Trains are merely referred to by their destination(s) by train operators and BART personnel (for example, “Richmond train” or “Richmond-bound train”). Electronic destination signs add “San Francisco” to the destination of any westbound transbay train or eastbound train west of San Francisco to make it clear that it will be passing through the city, and “SFO Airport” (or just “SFO”) is added to any train going to the airport. This can cause quite cumbersome destination descriptions, such as “San Francisco/Daily City train”, “San Francisco/SFO Airport/Millbrae train”, and “San Francisco/Pittsburg/Bay Point train.” Perhaps the longest such description is for trains leaving Millbrae, which say “SFO Airport/San Francisco/Dublin/Pleasanton," though this name is not currently being used. With the exception of the front car electronically flashing the destination, the rest of the exterior of the fleet does not provide obvious indication regarding the line to which the car belongs. Cars from various rail yards throughout the system are intermingled to form a train. However, newer legacy cars that have not undergone refurbishment may have a diminutive color decal that indicates its car number and its historical line membership. Since all station platforms are equipped with displays indicating the destination of each train, as well as voice announcements as trains approach the station and begin boarding, this usually does not pose a big problem.

BART makes aggressive use of interlining, where multiple lines merge and share the same stations and tracks. Four lines share the Transbay Tube, all San Francisco stations, the Daly City Station and West Oakland Station. As a result, there are times of significant congestion during peak hours as multiple lines vie for shared resources. Only a maximum frequency of 4½ trains per hour per line can be achieved after headways and dwell times are accounted for. The lack of passing tracks or sidings throughout this quadruple-interlining section makes for very challenging recoveries from traffic delays. San Francisco- and Peninsula-bound trains from the East Bay must ensure that proper sequencing is maintained prior to entering the merged section for operations to remain smooth and without significant delays.

Defunct lines

In 1996 when the I-680/State Route 24 interchange in Walnut Creek was overhauled for construction, BART added temporary commuter train service during rush hours, which ran between South Hayward and Concord stations. The service ceased when the interchange was finished.

At the time when the BART-SFO Extension opened on June 22, 2003, there was a Millbrae - SFO Line, a shuttle line that operated every 20 minutes between Millbrae and San Francisco Airport, formerly depicted as a purple line. This line has been defunct as of February 2004. It was replaced by the Dublin/Pleasanton - Millbrae line that stopped at SFO Station on its way to Millbrae. As of January 1, 2008, this service was completely eliminated; passengers traveling from points south to the airport have to board a train at Millbrae, travel to San Bruno, and then take a different train back to the airport.

Rolling stock

Refurbished B car interior

C (C1) car interior

BART operates four types of cars, built from three separate orders, totaling 669 cars.

The A cars and the B cars were built from 1968 to 1971 by Rohr Industries, an aerospace manufacturing company which had only recently made its foray into mass-transit equipment manufacturing, touting yet untested space-age design techniques. The A cars were designed as leading or trailing cars only, with a fiberglass operator's cab housing train control equipment and BART's two-way communication system. The A cars are distinguished by their aerodynamic leading edge extending 5 feet (1.5 m) longer than their B- and C-car siblings. A cars can comfortably seat 72 passengers, and under crush load, 150 passengers. B cars have no operator's cab and are used in the middle of trains to carry passengers only; B cars have the same passenger capacity as A cars. Currently, BART operates 59 A cars and 380 B cars.[1]. BART's livery has remained effectively unchanged throughout its history.

The C cars were built by Alstom between 1987 and 1989. The C cars have a similar fiberglass operator's cab and control and communications equipment as the A cars, but unlike A cars, do not have the aerodynamic nose design, thus allowing them to be used as middle cars as well. The dual purpose of the C cars allows faster train-size changes without having to move the train to a switching yard. C cars can comfortably seat 64 (4 seats were lost compared to the A/B cars by eliminating one row of seats to accommodate the operator’s cab and 4 additional seats were lost by eliminating one pair of seats next to the left-side forward door on each side to provide space for wheelchairs) and under crush load accommodate 150 passengers. The latest order, from Morrison-Knudsen (now Washington Group International), was for C2 cars, which are essentially the same as C cars, but feature an updated, third-generation interior with a blue/gray motif, in contrast to the previous blue and brown colors. C2 cars have flip-up seats near the left-side forward door to accommodate passengers in wheelchairs, and red lights on posts near the door to warn the hearing-impaired when the doors are about to close. C2 cars can comfortably seat 68 passengers (including the flip-up seats), and under crush load can carry 150 passengers. Since the purchase of C2s, the original C cars are also referred to as C1 cars. Currently, BART operates 150 C1 cars and 80 C2 cars.

In 1995, BART contracted with ADtranz (acquired by Bombardier Transportation in 2001) to refurbish and overhaul the 439 original Rohr A- and B-cars, updating the old vintage brown fabric seats to the less-toxic and easier-to-clean, light-blue polyurethane seats in use today and bringing the cars in general to the same level of interior amenities as the C2 fleet. The Rohr cars were also rebuilt with ADtranz 3-phase Alternating Current (AC) traction motors, model 1507C. The seven-year project was completed in 2002. All BART cars have upholstered seats and nearly all cars have carpeting except for one that is being used on a trial to accommodate bicycles and other maintenance purposes. Because one of the original design goals was for all BART riders to be seated, the older cars have fewer provisions such as grab bars for standing passengers. Newer cars are more accommodating in this area; however, unlike many other urban transit systems, hand straps are not found on BART trains. Flip-up seats (found in C2 cars) were excluded from the refurbishment (reducing seating capacity from 72 to 68), in order to provide designated areas for luggage, wheelchairs and bicycles. Consequently, the original C (or C1) cars have the oldest interior design, as they have not been refurbished and were not purchased recently enough to have the "newer" convenience features; for example, they lack vertical grab bars in the middle of the car and do not have the in-post red lights to warn of closing doors.

The A, B, and C cars were all given 3-digit numbers originally, but when refurbished 1000 was added to the number of each individual A/B car (e.g. car 433 would become 1433). The C2 cars are numbered in the 2500 series; the C/C1 cars still have 3-digit numbers.

The cars, which all have just two doors on each side, often cause extended wait times at stations as passengers must negotiate groups of standees in order to exit or enter the train. To speed up service, BART has considered introducing new, three-door cars.

Governance

The San Francisco Bay Area Rapid Transit District is a special governmental agency created by the State of California consisting of Alameda County, Contra Costa County, and the City and County of San Francisco. San Mateo County, which hosts six BART stations, is not part of the BART District. It is governed by an elected Board of Directors with each of the nine directors representing a specific geographic area within the BART district. BART has its own police force.

While the district includes all of the cities and communities in its jurisdiction, some of these cities do not have stations on the BART system. This has caused tensions among property owners in cities like Livermore who pay BART taxes but must travel outside the city to receive BART service. In areas like Fremont, the majority of commuters do not commute in the direction that BART would take them (many Fremonters commute to San Jose, where there is currently no BART service). This would be alleviated with the completion of a BART-to-San Jose extension project.

However, some cities and towns are near enough to cities with BART stations that residents commute via a bus or car to the nearest BART station. Emeryville, for instance, has no BART service, but has a free shuttle service, the Emery-Go-Round, that takes passengers to the nearby MacArthur station in Oakland. Similarly, Albany does not have a BART station of its own. The city's residents can go to either North Berkeley (in Alameda County) or El Cerrito Plaza (in Contra Costa County) stations for services. For those wishing to drive their cars to the stations instead, many BART stations offer many kinds of parking options.

Cost and budget

BART's initial cost was $1.6 billion, which included both the initial system and the Transbay Tube. Adjusted for inflation, this cost would be valued at $15 billion in 2004.

In 2005, BART required nearly $300 million in subsidies after fares. About 37% of the costs went to maintenance, 29% to actual transportation operations, 24% to general administration, 8% to police services, and 4% to construction and engineering. In 2005, 53% of the budget was derived from fares, 32% from taxes, and 15% from other sources, including advertising, station retail space leasing, and parking fees. BART's farebox recovery ratio of 53% is relatively high for a U.S. public transit agency operating over such long distances with high frequency (for comparison, see the article on farebox recovery).

Fares

Ticket vending machines at the Powell Street Station

Fares on BART are comparable to those of commuter rail systems and are higher than those of most metros, especially for long trips. The fare is based on a formula that takes into account both the length and speed of the trip. A surcharge is added for trips traveling through the Transbay Tube, to San Francisco International Airport, or through San Mateo County, which is not a BART member. Historically and up until only recently, passengers have used refillable paper-plastic-composite tickets, on which fares are stored via a magnetic strip, to enter and exit the system (a similar magnetic strip ticketing system is used on the Washington Metro in Washington, D.C). The exit faregate prints the remaining balance on the ticket each time the passenger exits the station. A paper ticket can be refilled at a ticket machine, the remaining balance on any ticket can be applied towards the purchase of a new one, or a card is simply captured by the exit gate when the balance reaches zero; multiple low value cards can be combined to create a larger value card, but only at specific ticket exchange locations which are located on some BART stations. BART relies on unused ticket values, particularly of patrons discarding low-value cards, as a source of revenue, approximated by some to be as high as $9.9 million.

A stored-value smart card fare system, called the TransLink smart card, will be rolled out as valid fare in spring 2008. This program was launched to the public in fall 2006 with rollout on AC Transit, Dumbarton Express, and Golden Gate Transit lines. BART participated in the Translink pilot program, installing readers at nine stations, but removed them once the pilot was completed. In the interim, BART has introduced the EZ Rider card, a pilot program using technology similar in design to the TransLink cards. Both are contactless smart cards, and contain stored value that can be used for fare payments. BART contracted with Cubic Transportation Systems to replace all the faregates with ones that have smart card readers inherently installed. The reader technology used for the EZ Rider system may not be compatible with the technology used for the Translink system, which might be a factor delaying the rollout of the system. The EZ Rider program is expected to last until the TransLink cards are accepted on BART, scheduled for spring 2008. The BART minimum fare of $1.50 is charged for trips under 6 miles (9.7 km), such as a trip between two adjacent Berkeley stations. The maximum one-way fare including all possible surcharges is $8, the 51 miles (82 km) journey between Pittsburg/Bay Point and San Francisco International Airport. The farthest possible trip, from Pittsburg/Bay Point to Millbrae, costs less because of the additional charge added to airport trips. Passengers without sufficient fare to complete their journey must use an AddFare machine to pay the remaining balance in order to exit the station. Because of the amount of the base fare, traveling between BART stations in downtown San Francisco on BART is the same price as the city's own light rail system, the MUNI Metro, which is generally slower in covering the same distance. However, MUNI permits around two full hours of riding, including transfers to other MUNI vehicles, whereas BART charges $1.50 for a single journey. There are various quirks in the fare system due to a subsidy being provided to riders traveling between some outlying stations. For example, for a trip from Dublin/Pleasanton to Fremont, it is less expensive to exit the station at the transfer point, Bay Fair, and re-enter the station, instead of staying on the platform, because you would get charged two $1.50 base fares instead of a $4.10 fare from end to end.

BART uses a system of five different color-coded tickets for regular fare, special fare, and discount fare to select groups as follows:

• Blue tickets – General: the most common type, includes high-value discount tickets
• Red tickets – Disabled Persons and children aged 4 to 12: 62.5% discount, special ID required (children under the age of 4 ride free)
• Green tickets – Seniors age 65 or over: 62.5% discount, proof of age required for purchase
• Orange tickets – Student: special, restricted-use 50% discount ticket for students age 13-18 currently enrolled in high or middle school
• BART Plus – special high-value ticket with 'flash-pass' privileges with regional transit agencies, including MUNI's buses.
• EZ Rider – A new plastic smart card fare program that will eventually be replaced by the TransLink Phase II Program in spring 2008

EZ Rider Fare Card

Unlike most transit systems in the United States, but like the MRT in Singapore, BART does not have an unlimited ride pass available and riders must pay for each ride they take. The only discount provided to the public is a 6.25% discount when "high value tickets" are purchased with fare values of $48 and $64, for prices of $45 and $60 respectively. Amtrak's Capitol Corridor & San Joaquins trains sell $10 BART tickets on-board in the café cars for only $8, resulting in a 20% discount. A 62.5% discount is provided to seniors, the disabled, and children age 5 to 12. Middle and high school students 13 to 18 may obtain a 50% discount if their school participates in the BART program; however, these tickets are intended to be used only between the students' home station and the school's station and for transportation to and from school events. However, these intended limitations are not enforced in any way and students are expected to behave on the honor system. The tickets are only usable on weekdays, a restriction that is enforced by the faregates. BART Plus tickets enjoy a last-ride bonus where if the remaining value is greater than $.05, the ticket can be used one last time for a trip of any distance. Most special discounted tickets must be purchased at selected vendors and not at ticket machines. The Bart Plus tickets can be purchased at the ticket machines. In particular, the middle and high school tickets are usually sold at the schools themselves.

Family members of BART employees receive special BART passes and can ride free-of-charge upon showing their pass and photo identification to the BART station attendant. Employees of airlines that take BART to work at San Francisco International Airport receive a fare discount of 25%, but non-airline employees who do the same receive no discount.

Fares are enforced by the station agent, who monitors activity at the fare gates adjacent to the window and at other fare gates through closed circuit television and faregate status screens located in the agent's booth. All stations are staffed with at least one agent at all times. Despite this, fare fraud occasionally occurs, usually as a result of people entering and exiting through the emergency exit gate, which are permitted for non-emergency use by passengers with bikes, in wheelchairs, and carrying luggage. It also occurs using elevators, which in some stations lead from the ticketed area to the unticketed area.

There is little fare coordination between BART and surrounding agencies. Some agencies accept the BART Plus pass, which at a fee of between $38 and $71 per month, permits pass holders to use BART and connecting buses. Most notably, AC Transit dropped out of the program due to the small amount of reimbursement they received from BART. Another fare coordination program permits adult monthly pass holders of the San Francisco Municipal Railway to ride BART trains within the city of San Francisco for free (with no credit applied to trips outside the city). The city of San Francisco pays BART $.87 for each trip taken under this arrangement. For riders who do not hold such passes, there is generally only a token discount ($.25 to $.50) provided to passengers transferring to and from trains to other transit modes. The Santa Clara Valley Transportation Authority does honor BART transfers for a local fare credit ($.50 to $1.75) towards the 120, 140, 180 and 181 trans-county express lines departing the Fremont BART station, but all riders are required to disembark in Santa Clara County. There is no credit applied when traveling towards the Fremont BART Station.

Proposals to simplify the fare structure abound. At one extreme, a flat fare that disregards distance has been proposed by BART director Joel Keller. The lesser extreme involves the implementation of a simplified structure that would create fare bands or zones. The implementation of either scheme would demote the use of distance-based fares and shift the fare-box recovery burden to the urban riders in San Francisco, Oakland and Berkeley and away from the suburban riders of East Contra Costa, Southern Alameda, and San Mateo Counties, where density is lowest, and consequently, operational cost is highest.

Automation

BART was one of the first U.S. systems of any size to have substantial automated operations. The trains are computer-controlled via BART's Operations Control Center (OCC) and headquarters at Lake Merritt and generally arrive with regular punctuality. Train operators are present to make announcements, close doors, and operate the train in case of unforeseen difficulties.

As a first-generation system, BART's automation system was plagued with numerous operational problems during its first years of service. Shortly after revenue service began, an on-board electronics failure caused one two-car test train (with car 143 as the lead car) to run off the end of the elevated track at the Fremont station and into a parking lot. This incident was dubbed the Fremont Flyer, and there were no serious injuries. When revenue service began, "ghost trains" (or false occupancies), trains that show up on the computer system as being in a specific place but don't physically exist, were common, and real trains could at times disappear from the system, as a result of dew on the tracks and too low of a voltage (at 0.6 volts rather than the industry standard 15 volts) being passed through the rails for train detection. Under such circumstances, trains had to be operated manually and were restricted to a speed of 25 mph (40 km/h). Enhancements were made to the train control system to address these "ghost trains" (or false occupancies). However, manual blocking that kept trains in stations until the train ahead had left its station were mandated for several years.

The original signaling technology and subsequent enhancements used to control the trains was developed by Westinghouse.

During this initial shakedown period, there were several episodes where trains had to be manually run and signaled via station agents communicating by telephone. This caused a great outcry in the press and led to a flurry of litigation among Westinghouse, the original controls contractor, and BART, as well as public battles between the state government (advised by University of California professor Dr. Bill Wattenburg), the federal government, and the district, but in time these problems were resolved and BART became a reliable service. Ghost trains apparently still persist on the system to this day and are usually cleared quickly enough to avoid significant delay, but occasionally some can cause an extended backup of manually operated trains in the system. In addition, the fare card system was easily hackable with equipment commonly found in universities, although most of these flaws have been fixed.

Connecting rail and bus transit services

BART has direct connections to two regional rail services – Caltrain, which provides service between San Francisco, San Jose, and Gilroy, at the Millbrae Station, and Amtrak's Capitol Corridor, which runs from Sacramento to San Jose, at the Richmond and Coliseum/Oakland Airport stations. A third Capitol Corridor connection at the Union City station is planned as part of a larger Dumbarton Rail Corridor Project to connect Union City, Fremont, and Newark to various peninsula destinations via the Dumbarton rail bridge. BART is the managing agency for the Capitol Corridor until 2010.

BART connects to San Francisco's local light rail system, the Muni Metro. The upper track level of BART's Market Street subway, originally designed for the lines to Marin County, was turned over to Muni and both agencies share the Embarcadero, Montgomery Street, Powell and Civic Center stations. Some Muni Metro lines connect with (or pass nearby) the BART system at the Balboa Park and Glen Park stations.

A number of bus transit services connect to BART, which, while managed by separate agencies, are integral to the successful functioning of the system. The primary providers include the San Francisco Municipal Railway (Muni), Alameda-Contra Costa Transit (AC Transit), San Mateo County Transit District (SamTrans), Central Contra Costa Transit Authority (County Connection), and the Golden Gate Bridge, Highway and Transportation District (Golden Gate Transit). Until 1997, BART ran its own "BART Express" connector buses, which ran to eastern Alameda County and far eastern and western areas of Contra Costa County; these routes were later devolved to sub-regional transit agencies such as Tri-Delta Transit and the Livermore Amador Valley Transit Authority (WHEELS) or, in the case of Dublin/Pleasanton service, replaced by a full BART extension.

BART is connected to Oakland International Airport via AirBART shuttle buses, which bring travelers to and from the Coliseum/Oakland Airport BART station. These buses are operated by BART and accept exact-change BART fare cards in addition to exact change. BART also connects to the San Francisco International Airport, though in this case the train actually enters the airport directly and no shuttle is necessary, although connections are available to AirTrain for those not departing or arriving from the international terminal.

Other services connect to BART including the Emery Go Round (Emeryville), WestCAT (north-western Contra Costa County), Benicia Transit (Benicia), Union City Transit (Union City), and the Santa Clara Valley Transportation Authority (VTA, in Silicon Valley).

The bus service connecting the University of California, Berkeley to the Berkeley BART station was once called Humphrey Go-BART, a spoonerism of the famous actor and director Humphrey Bogart. It has since been replaced by a number of regular AC Transit bus routes and shuttle bus routes operated by the university.

Other connecting services

BART hosts carsharing locations at many stations, a program pioneered by City CarShare. Riders can transfer from BART and complete their journeys by car. BART has started to offer long-term airport parking through a third-party vendor at most East Bay stations. Travelers must make an on-line reservation in advance and pay the daily fee of $5 before they can leave their cars at the BART parking lot.

Casual carpools have formed at North Berkeley station and the area around El Cerrito Del Norte station. The lots are convenient since most carpoolers use public transit back to their final destination. However, because of how BART charges for parking, passengers cannot park at most BART lots without paying a fare.

BART history

Origins and planning

The idea of an underwater electric rail tube was first proposed in the early 1900s by Francis "Borax" Smith. It is no coincidence that much of BART's current coverage area was once served by the electrified streetcar and suburban train network called the Key System. This early twentieth century system once had regular trans-bay traffic across the lower deck of the Bay Bridge. By the 1950s the entire system had been dismantled in favor of automobiles and buses and the explosive growth of highway construction.

Proposals for the modern rapid transit system now in service began in 1946 by Bay Area business leaders concerned with increased post-war migration and growing congestion in the region. An Army-Navy task force concluded that an additional trans-bay crossing would soon be needed and recommended a tunnel; however, actual planning for a rapid transit system did not begin until the 1950s. In 1951, California's legislature created the San Francisco Bay Area Rapid Transit Commission to study the Bay Area's long-term transportation needs. The commission's 1957 final report concluded the most cost-effective solution for the Bay Area's traffic woes would be to form a transit district charged with the construction and operation of a high-speed rapid rail system linking the cities and suburbs. Nine Bay Area counties were included in the initial planning commission.

The San Francisco Bay Area Rapid Transit District was formed by the state legislature in 1957, comprising the counties of Alameda, Contra Costa, Marin, San Francisco, and San Mateo. Because Santa Clara County opted instead to first concentrate on its Expressway System, that county was not included in the original BART District.

In 1959, a bill was passed in the state legislature that provided for the entire cost of construction of the tube to be paid for with surplus toll revenues from the San Francisco-Oakland Bay Bridge. This represented a significant portion of the total cost of the system.

By 1961, a final plan for the new system was sent to the boards of supervisors of each of the five counties. The system's initial plans were for four lines connecting Concord in the east, Richmond in the north-east, Fremont in the south-east, Palo Alto in the south-west, and Novato in the north-west. However, in April 1962 San Mateo County made the decision to opt out, citing high costs, existing service provided by Southern Pacific commuter trains, and concerns over shoppers leaving their county for stores in San Francisco. Marin County followed soon thereafter in May. Marin was forced out of the BART district because of engineering objections from the board of directors of the Golden Gate Bridge. BART officials refused to allow Marin supervisors to stay in the district because they were afraid Marin voters would not approve the bonds, which had to win more than 60% approval. The BART plans were finally approved by the voters of the three remaining participating counties in November 1962.

In the 1980s planning was underway for extension south from San Francisco, the first step being the Daly City Tailtrack Project, upon which turnaround project the San Francisco Airport Extension would later build.

Construction of the initial system

BART construction officially began on June 19, 1964 with President Lyndon Johnson presiding over the ground-breaking ceremonies at the 4.4-mile (7.1 km) test track between Concord and Walnut Creek in Contra Costa County.

The enormous tasks to be undertaken were daunting. System wide projects would include the construction of three underground rail stations in Oakland's populated downtown area, four stations through San Francisco’s downtown beneath Market Street, as well as four other underground stations in other parts of San Francisco, three subterranean stations in Berkeley (which paid more to bury them, in contrast to the stations in neighboring Oakland and El Cerrito), the 3.5 miles (5.6 km) tunnel through the Berkeley Hills; and of course the 3.6 miles (5.8 km) Transbay Tube between Oakland and San Francisco beneath the San Francisco Bay. Constructed in 57 sections, The Tube is the world's longest and deepest immersed tunnel at cost $180 million and was completed in August 1969.

Peter Hall, author of the book Great Planning Disasters, describes BART as one of the sensational planning disasters of the 20th century, alongside the Anglo-French Concorde and the Sydney Opera House.

Operation

BART began regular passenger service on September 11 1972, reporting more than 100,000 passengers in its first five days of operations. The Transbay Tube opened two years later on September 16 1974, thus linking each of four branches extending to Daly City, Concord, Richmond, and Fremont. During the first five years of operation, BART operated on a weekday-only schedule.

The 1989 Loma Prieta earthquake gave BART an unequaled opportunity to shine as a star and major hero during the catastrophe. Transportation between San Francisco and Oakland was affected drastically, with the breakage of a section of the San Francisco-Oakland Bay Bridge and the near-total destruction of the Cypress Street Viaduct. With some of the Bay Area's major freeways either heavily damaged or destroyed, BART trains, within six hours of the original earthquake, were again operational effectively becoming the sole mode of transportation throughout the area. Even with routine service interruptions following aftershocks for inspection of tracks, over- and under-crossings, and tunnels, BART remained operational.

BART prohibits eating, drinking, smoking, and graffiti past faregates, even at outside stations.

Expansion to the original system was made possible by a region-wide agreement under which San Mateo County was to contribute $200 million to East Bay extensions as a “buy-in” to the system without actually joining the BART district. Funds also came from many east county residents who paid into the system for many years. The North-of-Concord extension opened in two phases: service to North Concord/Martinez beginning on December 16 1995, and service to Pittsburg/Bay Point beginning a year later on December 7 1996. The first service south of Daly City began on February 24 1996, to Colma. A year later on May 10 1997, service began from Bay Fair to Castro Valley and Dublin/Pleasanton. Although the Dublin/Pleasanton extension is now a main trunk line, it was not originally conceived as such, but rather a shuttle service between the Dublin/Pleasanton and Bay Fair stations.

BART has a unionized work force that went on strike for two weeks in 1976 in solidarity with the BART Police Officers Association. During the 1970s, BART union workers received quarterly cost of living increases. With inflation running in excess of 18%, however, this policy became expensive. In 1979, there was a 90 day lockout by management, or a strike by union workers, depending on which side one believes. Trains were able to run during this period because one of the unions, AFSCME, was then only an informal association known as BARTSPA, and management and BARTSPA had enough staff to keep the trains running. One result of this strike is that the cost-of-living increases were greatly reduced to an amount far below the Consumer Price Index, and that such raises are only received if no other raise occurs in a particular year.

For six days in 1997, a BART strike caused a complete system-wide shutdown. This resulted in a four-year contract offering a 7% raise, and a one-time payment of $3,000 to all employees in lieu of a raise the first year. Such one-time payments are becoming more common as a way to prevent the effects of compounding on wages and salaries.

Unionized BART employees, particularly professionals, saw their wages and standard of living erode during the Silicon Valley economic boom that drove up real estate prices and salaries in the Bay Area in the 1990s. In addition, BART began large scale layoffs of rank and file workers, increasing the workload on those remaining. In its 2001 negotiations, the BART unions fought for, and won, a 24 percent wage increase over four years with continuing benefits for employees and retirees. Another threatened strike on July 6 2005 was averted by a last-minute agreement between management and the unions. In this agreement, Union workers received a 7% raise over four years, and paid an increase in the cost of medical insurance. The net increase (3%) is well below the current rate of inflation, which is about 4% per year (or 16 percent over the four-year contract); and also below the average private sector raise, which was 4.6% for 2006.

In October 2004, BART received the American Public Transportation Association's Outstanding Public Transportation System Award for 2004 in the category of transit systems with 30 million or more annual passenger trips. BART issued announcements and began a promotional campaign declaring that it had been named Number One Transit System in America. In 2006, the same industry trade group presented BART with the token AdWheel award for 'creative approaches to marketing transit' in recognition for BART's development of an iPod-based trip planner.

Incidents and accidents

BART has had relatively few accidents during its nearly four decades of operation. There have been no accidents attributed to brake failure. The following incidents are known to have occurred on the BART system:

• In 1972, shortly after the system opened, a train, dubbed the Fremont Flyer, failed to stop at the Fremont terminus station and ran off the tracks and into the station parking lot. However, it was only a test run and carried no passengers. There were no injuries.

• The tube was closed from 17 January to 4 April 1979, after a train caught fire while in the Transbay Tube, injuring dozens, killing a fireman, and damaging equipment. Most of the injuries were caused by inhalation of toxic smoke from the burning polyurethane in the seats, leading to a $118,000 replacement program which was completed in November 1980.

• On December 17, 1992, a BART train derailed south of 12th Street station and caused a five day closure of the line.

• On March 9, 2006, debris on BART tracks between Montgomery and Embarcadero stations caught fire and caused a 1.5 hour system-wide shutdown. Frustrated passengers accused BART of mishandling the incident.

• On March 28 and 29, 2006, BART experienced computer glitches in its system during rush hour, which left about 35,000 commuters stranded inside trains or stations while the problem was being resolved.

• On December 1, 2006, a BART train jumped the tracks near the Oakland Wye, between 12th Street and Lake Merritt stations. There were no injuries.

• On May 10, 2008, two separate early morning fires at different power substations disrupted service on the Fremont line. No injuries were reported from the incident. The resulting damage left the Fremont line impaired as several computer control loops went offline between South Hayward and Union City Stations. Train operators were forced to manually drive trains at 25 MPH. Normal service was finally restored on July 13th, 2 weeks before initial estimates.

San Francisco International Airport extension

The $1.5 billion extension of BART southward to San Francisco International Airport's (SFO) Garage G, adjacent to the International Terminal, was opened to the public on June 22, 2003. Ground was broken on the project in November 1997, adding four new stations including the SFO station, South San Francisco, San Bruno, and Millbrae. The Millbrae station has a cross-platform connection to Caltrain, the first of its kind west of the Mississippi. The airport extension used to run from SFO to Millbrae station, and operated with two motormen (train operators) — one on each end of the train — between the San Bruno and Millbrae stations to reduce dwell time at SFO during peak hours; the train entered the SFO stub-end station under the control of the primary motorman and exited in the opposite direction towards Millbrae controlled by the secondary. Since SFO is now the terminus of the line that serves it, this practice was discontinued as it would not reduce the in-transit time for any trips.

The airport extension project added 8.7 miles (14.0 km) of new railway; 6.1 miles (9.8 km) of subway, 1.2 miles (1.9 km) of aerial, and 1.4 miles (2.3 km) of at-grade track. The launch point was the Daly City Tailtrack project, which extended the tracks further south of the existing terminus in San Francisco and was completed in the 1980s.

The project has not been without problems, however. The SFO extension currently draws 35,107 daily riders, significantly less than its target of 50,000 average weekday riders. Another significant problem of note had been the rocky relationship between BART and San Mateo County Transit District (SamTrans) which was not a part of the BART district, but by agreement was responsible for the extension's operating costs. Fueled by the reality that the extension was not paying for itself, the acrimony between BART and SamTrans over changes and reductions in bus and train service reached a high. BART wanted to increase service to attract ridership, while SamTrans wanted to reduce service to trim costs. Thus, service along the extension was changed several times. Eventually SamTrans and BART worked out a deal in which SamTrans paid BART $32 million, plus approximately $2 million a year, and BART assumed all costs and control of operating the extension. The latest revision to the SFO service has Pittsburg-Bay Point trains running to SFO at all times. During peak times, Richmond trains will run to Millbrae, with Dublin-Pleasanton trains terminating at Daly City, and during off-peak hours (nights and weekends), Dublin-Pleasanton trains will run to Millbrae (replacing Richmond service on the extension). Consequently, the new routing requires passengers connecting between San Francisco International Airport and Oakland International Airport to make an additional transfer. In addition, the cessation of direct BART service between Millbrae and SFO requires Caltrain passengers wanting to travel to the airport to make an additional transfer at San Bruno Station.

Many critics of the SFO Extension contend the project was merely a cover for BART's ultimate goal of ringing the bay, eliminating Caltrain altogether.

Future expansion and extension

Warm Springs & San Jose extensions

An 8.7 km (5.4 mi) extension of BART southward past Fremont to the Warm Springs District in southern Fremont, with an optional station at Irvington between the Fremont and Warm Springs stations, is in the planning/engineering stage by BART planning staff. This extension received a green light from the federal government when the Federal Transit Administration issued a Record of Decision on October 24, 2006. The action enables BART to begin purchasing the necessary right-of-way for the project and receive state-administered federal funding to finance the project.

An extension to San Jose is undergoing planning by BART and the San Jose area's transportation district, the Santa Clara Valley Transportation Authority (VTA). Since Santa Clara County is not among the member counties of the BART District (having opted out of the district at its inception, like neighboring San Mateo county), VTA plans to build the extension within Santa Clara County. In December 2002, VTA purchased a freight railroad corridor from Union Pacific Railroad which would serve as much of the necessary right-of-way for both the Warm Springs and San Jose extensions for $80 million. The route would continue south from the Warm Springs station in Fremont. In Milpitas there would be one "optional" station, which is not currently planned to be built but remains an option as a future infill station, at Calaveras Blvd/SR 237 in downtown Milpitas. The next station in Milpitas would be at Montague Expressway, co-located with the existing VTA Montague light rail station. In San Jose, there would be an elevated station at Berryessa Road. Before crossing US 101, the BART right of way would enter the subway portal into downtown San Jose. The Alum Rock subway station would be on N 28th St between the Julian Ave and Santa Clara St. The Downtown San Jose station would be underneath Santa Clara St spanning the block from 3rd St to Market St. The Downtown San Jose station was combined in 2005 from earlier plans for separate subway stations at Civic Plaza/San Jose State University and Market Street. The Diridon/Arena station would be between the San Jose Arena and the Diridon train station, which currently serves Amtrak, Caltrain, ACE and VTA light rail. The BART subway would then turn north following the Caltrain route, exiting to the surface at a subway portal after crossing under I-880. The Santa Clara BART station would be co-located at the existing Santa Clara Caltrain station. Separate construction plans by San Jose International Airport would bring a people-mover train to the Santa Clara BART/Caltrain/ACE station.

For the subway segment in San Jose, VTA plans to use a tunnel boring machine for most of the length in order to reduce disruptions to downtown during construction. Only the station locations would have cut and cover construction. This is different than how the BART subways were built in San Francisco and Oakland, which used the cut and cover method. The construction of the cut and cover stations in downtown San Jose would still cause major though temporary disruption, including closing several blocks of Santa Clara St and severing the VTA light rail line at Santa Clara St.

As a very large public-works project, the San Jose extension is not without controversy. It draws opposition from many corners, especially where it competes for funding. Some opposition includes supporters of the expansion of other transit modes and systems, such as Caltrain commuter rail, as well as other areas of Santa Clara County which would not be directly served by the BART extension and other parts of the Bay Area that have competing transportation projects. Engineering and design remain to be completed. Part of the funding arrangements remain unresolved. The VTA has allocated funds for constructing BART using the proceeds from a sales tax referendum which was passed by Santa Clara County voters in 2000. But the agency does not have enough money to pay for all the projects included on the 2000 ballot measure, or all the post-construction operational costs of the BART extension. In addition, the San Jose extension project received a "not recommended" rating from the Federal Transit Administration, primarily due to the VTA's financial issues, placing the federal portion of the funding in jeopardy. According to a study by the Sierra Club, which is an opponent of the project, the taxpayer subsidy required to attract each new rider on this extension would be between $31 and $72 per rider per trip; this translates to a public subsidy of $62 to $144 per rider per round-trip, or $15,500 to $36,000 per rider per year over a 20-year period.

Oakland Airport Connector

Procurement is currently underway for a people mover that would directly connect the Coliseum station to the terminal buildings at Oakland International Airport. This connection would physically resemble the AirTrain connection to New York City's JFK Airport, in that passengers would leave standard subway cars at a nearby station and enter a specialized people mover to reach the airport itself. However, unlike the AirTrain, the Oakland Airport Connector will be operated by BART, and integrated into the BART fare system, with standard BART ticket gates located at the entrance to the station at the Airport end of the people mover. Construction of this extension is expected to start in 2007, with revenue service expected by 2011. The airport connector will provide connecting travelers that fly into SFO and out of OAK (or vice versa), the ability to make the connection exclusively by train with three train transfers (SFO AirTrain, two BART trains and OAK AirTrain) but no bus transfer.

eBART

An alternative plan for extension into the communities of Antioch, eBART calls for diesel multiple unit train service to be implemented from the existing Pittsburg/Bay Point station with a cross-platform transfer east along the Highway 4 corridor to the town of Byron, with the future possibility of service to Tracy in the San Joaquin Valley. New stations would be located in Pittsburg, Antioch, Oakley, Brentwood, and Byron. Another option would be a Caltrain-like service on the existing Union Pacific right-of-way from North Concord to Brentwood and beyond to Tracy and Stockton, though such a project would be subject to problems associated with using non-dedicated rights of way. Service was expected to start in 2010 but the project has been delayed.

'tBART': I-580/Tri-Valley Corridor

This extension of either conventional BART or diesel multiple unit BART service would go from Dublin/Pleasanton station east to Livermore and over the Altamont Pass into Tracy and the Central Valley along I-580. It could possibly also go north through Dublin, San Ramon, Danville, and Alamo to the existing Walnut Creek station via the I-680 corridor.

Currently, a petition to extend BART to Livermore is being circulated by Linda Jeffery Sailors, the former mayor of Dublin, California.

The extension of conventional BART rail to Tracy is considered unlikely, as San Joaquin County, in which Tracy is located, is not part of the nine district counties and does not pay into the regional BART tax. The extension of third-rail BART, which would require exclusive and grade-separated rights-of-way over such a long distance, would be substantially more expensive. With conventional rail, existing trackage can be used, and incremental upgrades (such as grade separations at selected intersections, overhead electrification, signaling improvements, utilities relocation, etc.) are possible as funding dollars become available, but choosing BART would require a full build-out of the system initially, along with comprehensive funding.

An existing diesel commuter rail line, the Altamont Commuter Express (ACE) currently operates on much of this route. A free shuttle transfers passengers between the ACE Pleasanton station and the BART Dublin/Pleasanton station, linking the two systems.

'wBART': I-80/West Contra Costa Corridor

A corridor study of extending the service north from the Richmond Station is underway with numerous options being studied. One would create commuter rail service utilizing lightweight diesel multiple units (DMU) to operate on existing or new tracks. In order to operate on existing tracks with freight service, however, heavier-weight DMU vehicles adhering to Federal Railroad Administration regulations would need to be used. This option is known as wBART. A second option would create a commuter rail service running from the BART terminus along the Amtrak line to Hercules and possibly Fairfield and Vacaville in Solano County, similar to the Caltrain or ACE train services. Yet another option would extend conventional BART to a North Richmond station near the Richmond train yard at 13th Street/Rumrill Avenue and Market Street, then continue along the existing Southern Pacific rail line and the Richmond Parkway expressway to Interstate 80. The service would have a Hilltop station and then continue along I-80 to State Route 4 in Hercules, near Hercules Transit Center. Service would continue along I-80 through Vallejo until the I-505 interchange in Vacaville. Finally, a proposed option would stretch BART westward across the Richmond-San Rafael Bridge into central Marin County.

Infill stations

BART planners have studied and/or planned infill stations for at least three sites within the system. Infill stations are stations constructed on existing line segments between two existing stations. Construction costs for a planned 30th Street Mission station in San Francisco, between the existing 24th Street Mission and Glen Park stations, are estimated at approximately $500 million. A proposal for a Jack London Square station in Oakland was rejected as being incompatible with existing track geometry. A one-station stub line to Jack London Square at the foot of Broadway and the use of other transit modes also were studied.

The new infill West Dublin/Pleasanton station is currently under construction in the median of I-580, just west of the I-680 interchange between the Castro Valley and Dublin/Pleasanton stations. Construction estimates for this station are $100 million, with funding coming from a unique public-private partnership and transit-oriented development (TOD) project on adjacent BART-owned property. Construction on the station began in October 2006, and is slated for completion in 2009.

BART compared with other rail transit systems

BART, like other transit systems of the same era, endeavored to connect outlying suburbs with job centers in Oakland and San Francisco by building out lines that paralleled established commute routes of the region's freeway system. The majority of BART's service area, as measured by percentage of system length, consists of low-density suburbs. Unlike the New York City Subway or the London Underground, individual BART lines were not designed to provide frequent local service, as evidenced by the system's current maximum achievable headway of 13.33 minutes per line through the quadruple interlined section. Muni provides local light-rail and subway service within San Francisco city limits and runs with smaller headways than does BART. BART could in many ways be characterized as a "commuter subway," since it has many characteristics of a commuter rail system, including lengthy lines that extend to the far reaches of suburbia with significant distances between most adjacent stations. However, in the urban areas of San Francisco and downtown Oakland, multiple lines converge, and BART takes on the characteristics of an urban subway, including short headways and transfer opportunities to other lines.

Many of the suburban stations—particularly those in Contra Costa County, southern Alameda County, and San Mateo County—have park and ride facilities. These stations are spaced two or more miles (3 km) apart and offer free or subsidized parking; thus many lots are filled to capacity for the morning commute. To augment its revenues, BART charges for parking at select stations, however the agency has garnered criticism that its parking fees are too heavily subsidized and are thus significantly below the market-clearing rate, as evidenced by the capital outlays of building an individual parking space at between $15,000 and $39,000 per space. A unique feature of BART parking is that parking fees are paid, not upon exiting the lot, but immediately after passing through the fare gates and just prior to entering the train platform areas.

As such, some sources consider BART to be more of a regional commuter rail service, such as the Berlin S-Bahn or the Paris RER. However, BART also possesses all the qualities and services of a metro system, including electrified third-rail propulsion, exclusive grade-separated right-of-way, frequent headways in its urban service areas, and pre-paid fare card access. Urban stations are as close as one-half mile (800 m) apart and have combined 2.5- to 5-minute service intervals at peak times. These factors contribute to the consideration of BART as a hybrid metro-commuter system, functioning as a metro in the central business districts of San Francisco, Oakland and Berkeley, and as commuter rail in the region's suburban areas.

A recent study shows that along with some Bay Area freeways, some of BART's overhead structures could be extensively damaged and could potentially collapse in the event of a major earthquake, which is predicted as highly likely to happen in the Bay Area within the next 30 years. Extensive seismic retrofit will be necessary to address many of these deficiencies, although one in particular, the penetration of the Hayward Fault Zone by the Berkeley Hills Tunnel, will be left for correction after any disabling earthquake, with the consequences for in-transit trains, their operators, and their passengers left to chance.

By November 2005, BART had become the first transit system in the nation to offer cellular communication to passengers of all wireless carriers on its trains underground. As of summer 2006, service is available for customers of Verizon Wireless, Sprint/Nextel, AT&T Mobility, and T-Mobile in and between the four San Francisco Market Street stations from Civic Center to Embarcadero. This is in contrast to other systems in US, which, while having some cellular service, do not provide it for passengers of all the major cell phone carriers. Coverage is eventually planned for the entire system, with coverage for the segment between Balboa Park and 16th St. Mission by the middle of 2007 and between Lake Merritt and 19th St./Oakland some time after that.

Since the mid 1990s, BART has been trying to modernize its aging 30-year-old system. The aforementioned fleet rehabilitation is part of this modernization; presently, fire alarms, water-sprinkling systems, yellow tactile platform edge domes, and cemented-mat rubber tiles are being installed. The rough black tiles on the platform edge mark the location of the doorway of approaching trains, allowing passengers to wait at the appropriate locations for the train, instead of waiting until the train arrives to figure out where to board. All faregates and ticket vending machines have also been completely replaced. BART'S original Ticket machines had Nixie Tube Displays to show the amount of money inserted into the machine.

On April 10, 2007, BART General Manager Tom Margro, who has been BART chieftain for eleven years, announced his retirement.

In late May, 2007, BART stated its intention to improve non-peak (night and weekend) headways for each line to only 15 minutes. The current 20-minute headways at these times is viewed as a psychological barrier to ridership. June 2007, BART temporarily reversed its position stating that the shortened wait times would likely not happen due to a $900,000 state revenue budget shortfall. Nevertheless, BART eventually confirmed the implementation of the plan by January 1, 2008.

Furthermore, in June 2007, BART suddenly removed all references to implementation of the Translink payment system from their website. BART spokesperson Marty Moran stated (via email) that Translink now may be implemented as early as late 2007. Implementation of Translink on BART was pushed back even further due to disputes regarding the processing of fares between MTC and BART. Translink will now be rolled out simultaneously on BART, SF Muni, and Caltrain in Spring 2008.

As BART celebrated the 50th anniversary of its creation by the state legislature, it announced its plans for the next 50 years. Its vision includes adding a four-bore transbay tube beneath San Francisco Bay that would run parallel and south of the existing tunnel and emerge at the Transbay Transit Terminal to provide connecting service to Caltrain and the proposed future California High Speed Rail system. The four-bore tunnel would provide two tunnels for BART and two tunnels for conventional/high-speed rail. BART's plan focus on improving service and reliability in its core system (where density and ridership is highest), rather than extensions into far-flung suburbia. These plans include: a line that would continue from the Transbay Terminal through the South-of-Market, northwards on Van Ness and terminating in western San Francisco along the Geary corridor, the Presidio, or North Beach; a line along the I-680 corridor; a fourth set of tracks through Oakland.

BART recently detailed their upcoming service changes, beginning January 1, 2008. Among the changes, the Pittsburg/Bay Point line will extend to the SFO station (at all hours of operation), but will not continue to Millbrae. (A few red eye Pittsburg/Bay Point trains will extend to Millbrae in addition to serving SFO). During weekdays (excluding nights), the Richmond line will extend to the Millbrae station (bypassing the SFO station); during weeknights and weekends, the Dublin/Pleasanton line will extend to Millbrae (also bypassing SFO). This does mean that there will no longer be a direct connection between the airport and Millbrae, introducing an inconvenience for Caltrain system passengers wishing to travel to SFO. BART discontinued this citing low ridership between Millbrae and SFO, however they claim that there will be timed transfers at the San Bruno station for passengers connecting from SFO to Millbrae. Additionally, there will be a 5.4% fare increase, with the minimum fare increasing from $1.40 to $1.50.

In 2008 BART announced that it would install solar power systems at on the roofs at its train yards and maintenance facilities in Richmond and Hayward in addition to car ports with rooftop solar panels at its Orinda station. The board lamented not being able to install them at all stations but it stated that Orinda was the only station with enough sun for them to make money off of.
