（簡稱加州高鐵局）計劃籌備，未來亦由同單位設計、建造與經營整條高速鐵路。整個執行計畫在2005年8月通過，預計從計劃階段到第一階段通車須至少花費八到十年的時間。自2007年起整個計劃正在進行環境評量中。全線行車速度設計為最高可達350 km/h，連接舊金山與洛杉磯，並減短路程到兩小時半之內.

 California High-Speed Rail is a controversial planned high-speed rail system in the state of California to be run by the California High-Speed Rail Authority, commonly referred to simply as the Authority. The planned line would connect Los Angeles with San Francisco with future extensions south to San Diego and north of Sacramento. Initial funding for the project was approved by California voters on November 4, 2008, with the passage of Proposition 1A authorizing the issuance of US$9.95 billion in general obligation bonds for the project. This latest price estimate by the Authority for a Full Build option is $91.4 billion (in year-of-expenditure dollars), according to the 2012 Business Plan.

 According to the Authority website, it is "responsible for planning, designing, building and operation of the first high-speed rail system in the nation. California high-speed rail will connect the mega-regions of the state, contribute to economic development and a cleaner environment, create jobs and preserve agricultural and protected lands. By 2029, the system will run from San Francisco to the Los Angeles basin in under three hours at speeds capable of over 200 miles per hour. The system will eventually extend to Sacramento and San Diego, totaling 800 miles with up to 24 stations. In addition, the Authority is working with regional partners to implement a state-wide rail modernization plan that will invest billions of dollars in local and regional rail lines to meet the state’s 21st century transportation needs." Criticisms of the plan have advocated alternatives and highlighted the costs of the project.

中國中鐵在中國已完成總長2萬5000公里的鐵路，占全國四分之一。該公司工程單位還前進南非、中東，這些高鐵經驗可分享加州，尤其加州高鐵需穿過隧道、橋樑，也行經人口密集的都會區，都和中國高鐵工程類似。

中國高鐵加油,CHSR對美國做出整體性的高速鐵路從規劃,探勘,設計,施工,營運,管理,養護及售後服務皆可以和西班牙,德國,英國,法國,日本的高速鐵路競爭,加油中國高鐵5年以後筆者將重遊美國加州探訪親朋好友,預祝中國高鐵美國加州得標成功,為美國高速鐵路建設貢獻,展現中國人的驕傲並告慰150年前華裔鐵路勞工犧牲奉獻建設美國鐵路在天之靈,只不過如今的鐵路工程建設大都以機械設備代替勞工人力,否則中國定會派出10萬人鐵路建設部隊大軍,以為美國效力竣工後就留下來美國生活,繁衍下1代?

歷史真的會重演?
