The Dublin/Pleasanton–Daly City line is a Bay Area Rapid Transit (BART) line in the San Francisco Bay Area that runs between Dublin/Pleasanton station and Daly City station. The line is colored blue on maps, and BART sometimes calls it the Blue Line.^[2] It has 18 stations in Dublin, Pleasanton, Castro Valley, San Leandro, Oakland, San Francisco, and Daly City.

History[]

Of BART's five primary rapid transit services, the Dublin/Pleasanton–Daly City line was the most recent to open. Service began when the Dublin/Pleasanton extension opened on May 10, 1997.^[3] The West Dublin/​Pleasanton infill station was added to the line on February 19, 2011.^[4]

SFO/Millbrae extension service[]

When the SFO/Millbrae extension opened on June 22, 2003, BART extended the Dublin/Pleasanton–Daly City line to SFO. BART truncated this line back to Daly City and rerouted the Pittsburg/Bay Point line to San Francisco International Airport in its place on February 9, 2004. 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 this 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 for BART receiving additional fixed funding from SamTrans and other sources.^[5] BART has since again increased service south of Daly City, but this line now terminates at Daly City.

2019–2021 changes[]

MacArthur-bound train at 19th Street Oakland in February 2019

On February 11, 2019, the line began operating between MacArthur station and Dublin/Pleasanton station on Sundays. The change was to allow single-tracking in the Market Street Subway during electrical work, with only the Antioch–SFO/Millbrae line running through the Transbay Tube to serve San Francisco.^[11]

Sunday service to San Francisco resumed on February 16, 2020, with trains terminating at Montgomery station during single-tracking work and Daly City at other times.^[12] Trains terminated at 24th Street Mission during single-tracking work from September 20, 2020, until March 22, 2021, when Montgomery again became the terminal.^[13][14]
