California High-Speed Rail (CAHSR) is a publicly funded high-speed rail system being developed in California by the California High-Speed Rail Authority. Phase 1, about 494 miles (795 km) long, is planned to run from San Francisco to Los Angeles and Anaheim via the Central Valley, and is partially funded and under construction. A proposed Phase 2 would extend the system north to Sacramento and south to San Diego, for a total of 776 miles (1,249 km). The project was authorized by a 2008 statewide ballot to connect the state's major urban areas and reduce intercity travel times. Phase 1 targets a travel time of 2 hours and 40 minutes from San Francisco to Los Angeles, compared to about nine hours on existing Amtrak service.
