<P> The CAHSRA was established by an act of the California State Legislature and tasked with presenting a high - speed rail plan to present to the voters . This plan, Proposition 1A, was presented to and approved by voters in 2008 and included a $9 billion bond to begin construction on the initial leg of the network . Construction began in 2015 after a groundbreaking ceremony in Fresno . Completion of the initial operating segment between San Jose Diridon Station and Bakersfield with a spur to Merced is expected in 2025, and the complete first phase between San Francisco and Anaheim is expected in 2029 . Phase 2 extensions to Sacramento and San Diego are still in the planning stages . </P> <P> AB 3034, the authorizing legislation for Proposition 1A (which was submitted to the voters and approved), specified certain route and travel time requirements . Among these were that the route must link downtown San Francisco with Los Angeles and Anaheim, and link the state's major population centers together "including Sacramento, the San Francisco Bay Area, the Central Valley, Los Angeles Basin, the Inland Empire, Orange County, and San Diego ." The first phase of the project must link San Francisco with Los Angeles and Anaheim . Up to 24 stations were authorized for the completed system . </P> <P> This system will be built in two phases . Phase 1 will be about 520 miles (840 km) long, and is planned to be completed in 2029, connecting the downtowns of San Francisco, Los Angeles, and Anaheim using high - speed rail through the Central Valley . In Phase 2, the route will be extended in the Central Valley north to Sacramento, and from Los Angeles east through the Inland Empire and then south to San Diego . The total system length will be about 800 miles (1,300 km). Phase 2 has no dates as of yet . </P> <P> On February 18, 2016, the Authority released its 2016 Draft Business Plan, which significantly altered its near - term plans for the system implementation . While construction was always intended to begin in the Central Valley, the Initial Operating Section has always had two options: extend from the Central Valley northward toward the Bay Area (the IOS - North, San Jose to Bakersfield), or southward to Southern California (IOS - South, Merced to San Fernando Valley). In the 2012 and 2014 Business Plans the goal was to implement the IOS - South, but a more recent analysis of the funding available and time necessary to bring an IOS online the Authority is now proposing the IOS - North be implemented instead . This is being called the Silicon Valley to Central Valley Line, and it is expected that sufficient funding will be available to bring this segment online by 2025 . The Authority remains committed to pursue additional funding to complete the Phase 1 system by 2029 . </P>
