BART Yellow Line|

The Pittsburg/Bay Point - SFO Line of the Bay Area Rapid Transit system in the San Francisco Bay Area consists of 25 metro stations from Pittsburg/Bay Point to San Francisco International Airport. It passes through Concord, Pleasant Hill, Walnut Creek, Lafayette, Orinda, Oakland, San Francisco, Daly City, Colma, South San Francisco, and San Bruno.

When BART officially opened the extension to the San Francisco International Airport on June 22, 2003, this line bypassed the airport and went straight to Millbrae; only the Dublin/Pleasanton Line served the airport's station. In order to attract more riders, BART truncated the Dublin/Pleasanton Line back to Daly City on February 9 2004, in favor of the Pittsburg/Bay Point Line, which generally carried more passengers. However, BART, at the urging of SamTrans (which pays the operating expenses for BART's SFO extension) announced on August 11, 2005, that it was scaling back service on this line; effective September 12, 2005, Pittsburg/Bay Point trains once again terminated at Daly City Station. [http://www.sfgate.com/cgi-bin/article.cgi?f=/c/a/2005/08/12/BAGV9E6VFG1.DTL] .

Now as of January 1, 2008, the Pittsburg/Bay Point Line became reidentified on maps as the Pittsburg/Bay Point – SFO Line, as service to/from the stations between Daly City and SFO was reinstated during all of BART's operating hours, with service to Millbrae station during the first and last hour of service each day. At other times the Richmond - Millbrae line or Dublin/Pleasanton – Millbrae line serves the Millbrae station.

BART lines are usually not referred to by the color that identifies them on official system maps, so this line is rarely called the Yellow Line and the term has only recently come into use by BART officials. [http://www.insidebayarea.com/search/ci_5881409] It is commonly called the Pittsburg/Bay Point Line, though a few people may still call it the Concord Line, after its original termination point in Contra Costa County.

This line generally operates the longest trains in the system, with ten car trains common throughout the day and eight or nine car trains at night and on weekends. In addition, peak hour service is operated on the line to Pleasant Hill and Concord, supplementing the normal BART headway of 15 minutes on weekdays and 20 minutes on nights and weekends.

Future Plans

BART is planning the Pitsburg/Bay Point line to be built all the way to Brentwood in the future. Fact|date=July 2008
