Richmond–Millbrae line
The Richmond–Daly City/Millbrae line is a Bay Area Rapid Transit line in the San Francisco Bay Area that runs from Richmond station to Millbrae station. It has 23 stations in Richmond, El Cerrito, Berkeley, Oakland, San Francisco, Daly City, Colma, South San Francisco, San Bruno, and Millbrae. The line shares tracks with the five other mainline BART services.
The line is colored red on maps, and BART has begun to call it the Red Line It runs until 9 pm on weekdays and until 7 pm on Saturdays. Saturday service terminates at Daly City station rather than Millbrae; the SFO–Millbrae line provides service to Millbrae at times that the Richmond line does not.
Service history
The Richmond–Daly City/Millbrae line was the fourth of BART's five primary rapid transit lines to open. A few trains a day began running between Richmond and Daly City in April 1976, and all-day service began on July 7, 1980 after BART reduced its mandated train headway through the Transbay Tube.Citing increased ridership, BART extended weekday service on this line from 7pm to 8pm starting September 10, 2012. BART further extended service until 9pm on weekdays starting September 14, 2015.
SFO/Millbrae extension service
When the SFO/Millbrae extension opened on June 22, 2003, the Richmond–Daly City/Millbrae line continued to terminate at Daly City. BART extended this line to SFO and Millbrae during weekday peak hours 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 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 for BART receiving additional fixed funding from SamTrans and other sources. BART has since again increased service south of Daly City, and this line now terminates at Millbrae on weekdays and Daly City on weekends.
