Operations Control Center (OCC)
The current Operations Control Center (OCC) replaced the old "central control room," which made history when the system first opened in 1972, with what was considered the largest monitor display board of its kind in the country. The OCC functions as the nerve center of BART's 104-mile system, performing supervisory control of train operations and remote control of electrification, ventilation and emergency response systems. The display boards use computer imaging and video projection to display the entire system, combining information into two: one for track and train positions and the other for maintenance information and electrification. Stations and wayside - Network of control devices and track circuits controlling train speeds, stops and safe spacing. Backup train protection system - Sequential Occupancy Release System (SORS): 52 mini-computers in 26 stations.
Automatic Fare Collection (AFC)

Station Equipment
300 ticket vending machines, 579 faregates, and 168 addfare machines supplied by Cubic Transportation Systems, Inc. Ticket vending machines in the free area of BART stations accept cash as well as debit/credit cards and vend regular BART Blue as well as BART Plus tickets.  The ticket vending machines also eventually will load value on Translink smart cards.  Addfare machines are located in the paid area of the stations, and are intended for use by customers who need to add value to their BART ticket in order to exit the system.  Addfare machines accept cash only.  In some stations, Addfare machines also serve for parking validation/payment.  See individual stations descriptions to identify parking validation/payment requirements.  Additionally, there are over 80 bill-to-bill change machines located throughout the BART system.  These machines break $10 and $20 bills into $5 denominations, for use in the ticket vending machines and addfare machines.

Entry fare gate
Records time, date, station; returns ticket.

Exit fare gate
Computes fares, informs if additional payment is needed or deducts proper amount from the ticket.  The exit gate keeps "exact fare" tickets, and returns all other tickets with their remaining value printed on them.

Accessible gate
This is a wider gate to accommodate passengers with wheelchairs, bikes, strollers and baggage.  It serves as both an entry and exit gate, with ticket slots on both the entry and exit ends.  It works in the same manner as the regular fare gates.

Ticket Information

BART Tickets
BART tickets are plastic, credit-card sized, with magnetically encoded value.  Fare gates automatically deduct trip fares from the stored fare value on ticket.  Just like a regular credit card, the magnetic BART ticket should always be kept dry and away from magnetic sources and should not be folded or bent.

The Clipper fare payment system is a Bay Area regional project managed the Metropolitan Transportation Commission. Clipper provides Bay Area transit customers a single fare payment medium for all their transit trips, through use of electronic "smart card" technology.

BART fares are based on how far you travel. To check fares visit the Fare Calculator. Discounted tickets are available at participating banks, retailers, social-service agencies and community-based organizations and the BART Customer Service Office. Discount tickets are not available at BART Stations. Children 4 and under ride free, children 5 through 12, senior citizens (age 65 and over) and persons with disabilities are eligible for discounts. Visit the Ticket section for more information.
