Nominal height from top of rail to rooftop 12ft 8-1/8 in. Nominal height from top of rail to floor 3ft 3 in.

The BART to Antioch extension trains are Diesel Multiple Unit (DMU). They are fueled by renewable diesel, an advanced biofuel produced from bio-based sources such as vegetable oil.

Speed
70 mph maximum; 35 mph average, including 20-second station stops. For BART to Antioch DMU trains, the maximum speed is 75 mph; 60 mph average.


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 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.

A centralized control center is needed to operate the BART to Antioch DMU system independent of BART operations. It is located in the maintenance annex north of State Route 4 near the Antioch Station. A dispatch, control and monitoring desk at the Central Control Facility is used to communicate with transit operations and maintenance personnel. The facility is also linked to the Operations Control Center to allow synchronization of operations at the DMU Transfer Platform.
  
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. Addfare machines are located in the paid area of the stations, and are intended for use by customers who need to add value to exit the system. Addfare machines accept cash, credit and debit. In some stations, Addfare machines also serve for parking validation/payment. 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.

Fares

Clipper
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 and pay by phone options.

BART Tickets
BART stopped selling paper tickets in 2020 and stopped accepting paper tickets on November 30th, 2023. 

The BART magnetic ticket, with its blue and black stripes and simple white arrows pointing straight, has become an iconic piece of ephemera in the San Francisco Bay Area.  

BART had offered:

A blue ticket for adults.
A green ticket for seniors 65 and older. 
A red BART ticket for disabled individuals and youth ages 5 through 18.
A “BARTPlus” ticket, which was terminated in 2015 and would later be replaced by Clipper Card.

Fares
BART fares are based on how far you travel. To check fares visit the Fare Calculator. Fares are paid for with a Clipper card, which is the Bay Area’s all-in-one transit card administered by the Metropolitan Transportation Commission. Clipper is reusable, reloadable, and regionally accepted on other transit systems. Children 4 and under ride free, children 5 through 18, senior citizens (age 65 and over), persons with disabilities, and low income residents are eligible for discounts. Visit the Ticket section for more information.

Proof of eligibility is required for discount tickets and Clipper cards and therefore are not available at station vending machines. Discount Clipper cards can be obtained by mail or in person at multiple locations across the Bay Area
