The Pittsburg/Bay Point–SFO/Millbrae line is a Bay Area Rapid Transit (BART) line in the San Francisco Bay Area that runs from Pittsburg/Bay Point station to the SFO and Millbrae stations. It has 26 stations in Pittsburg, Bay Point, Concord, Pleasant Hill, Walnut Creek, Lafayette, Orinda, Oakland, San Francisco, Daly City, Colma, South San Francisco, San Bruno, and Millbrae.

BART colors this line yellow on maps but does not refer to it by color. It is commonly called the Pittsburg/Bay Point line, or alternatively the Concord line for its original terminus.

This line runs to Millbrae station after 8pm on weekdays and all day on weekends when the Richmond–Daly City/Millbrae line terminates at Daly City or is not running. At other times, SFO–Millbrae passengers can transfer between the Richmond–Daly City/Millbrae line and this line at San Bruno station.

The Pittsburg/Bay Point–SFO/Millbrae line was the second of BART's five lines to open. Service from Concord to MacArthur began on May 21, 1973. The line was extended to Daly City when the Transbay Tube opened on September 16, 1974. The North Concord/Martinez, Colma, and Pittsburg/Bay Point stations were added in 1995-1996.[1]

This line has BART's longest average train length with many ten-car trains on weekdays and eight/nine-car trains on evenings and weekends. It is BART's only line with short turn trains that augment the regular 15-minute-interval full-distance trains. Each weekday during peak hours, 15 short turn trains per direction terminate at Daly City, 24th St., or Montgomery to the west and Pleasant Hill or beyond to the east.

SFO/Millbrae extension service[edit]

When the SFO/Millbrae extension opened on June 22, 2003, BART extended the Pittsburg/Bay Point–SFO/Millbrae line to Millbrae but bypassed SFO. BART rerouted this line to SFO in place of the Dublin/Pleasanton line on February 9, 2004, with service extended to Millbrae outside of weekday peak hours. San Mateo County is not a member of the San Francisco Bay Area Rapid Transit District, so SamTrans funded the county's BART service. When the extension's lower-than-expected ridership caused SamTrans to accrue deficits, BART agreed to SamTrans' request to operate only the Dublin/Pleasanton line south of Daly City effective September 12, 2005.

SamTrans and BART reached an agreement in February 2007 in which SamTrans would transfer control and financial responsibility of the SFO/Millbrae extension to BART. In return, BART would receive additional fixed funding from SamTrans and other sources.[2] BART has since again increased service south of Daly City, and this line now terminates at SFO on weekdays, with service extended to Millbrae on evenings and weekends.

Expansion plans[edit]

As part of BART's East Contra Costa extension project, a new eBART line will extend BART service to Antioch station in 2017. A new transfer platform just east of the Pittsburg/Bay Point station will allow transfer between the Pittsburg/Bay Point–SFO/Millbrae line and the eBART line. eBART will run a fleet of Diesel Multiple Unit trains. Current proposals call for eBART to be eventually extended to Brentwood and Byron.
