predated the All Nighter initiative. Overnight service has consistently operated within San Francisco, but service outside of San Francisco has been inconsistent, rising and falling with the financial fortunes of the various transit agencies. AC Transit's long-standing overnight service was completely withdrawn in 1996, restored in 1999, and expanded in later years. SamTrans introduced overnight service to SFO in 2001 and maintained it with a subsidy from the airport starting in 2003. VTA introduced overnight service on Route 22 and the light rail network, but later withdrew overnight light rail service due to financial difficulties. Golden Gate Transit, which had long offered an essentially 24-hour service on Route 80 to Santa Rosa, reduced the span of service in 2003. 24-hour service was one of the issues considered in the Metropolitan Transportation Commission's 2001 Lifeline Network study, which detailed the transportation needs of economically disadvantaged individuals. Discontinued routes The All Nighter service initially included County Connection Route 820, which operated between downtown Oakland and central Contra Costa County. This route was discontinued effective December 28, 2008 due to budgetary problems and low ridership. Route 820 operated between downtown Oakland and Concord BART. WHEELS Route 810 was another initial service offering which operated between Bay Fair BART in San Leandro and Livermore via Dublin/Pleasanton BART. Route 810 was discontinued effective June 27, 2009 due to budgetary problems and low ridership. Additional service from Bay Fair BART to Castro Valley BART via AC Transit Route 880 was discontinued effective March 28, 2010 due to that agency's budgetary problems. Route 880 operated between Bay Fair BART and Castro Valley BART. Weekend service to Pittsburg/Bay Point BART via AC Transit Line 822 was introduced as a one-year pilot program in December 2014; it was discontinued one year later effective December 20, 2015 due to low ridership. Line 822 operated weekends from San Francisco to Pittsburg/Bay Point BART via Oakland, Pleasant Hill BART and Walnut Creek BART. Late Night Transportation Working Group In April 2014, Supervisor Scott Wiener formed the Late Night Transportation Working Group to study options for improved public transportation in and around San Francisco. In September, the Working Group announced that BART would test more frequent service for AC Transit route 800, cutting headways from 30 to 20 minutes, and introduce service from San Francisco to Pittsburg/Bay Point BART via a new AC Transit route 822.
