California High-Speed Rail Authority

California High-Speed Rail (CAHSR) is a publicly-funded high-speed rail system under construction across California by the California High-Speed Rail Authority. The project was authorized by a 2008 statewide ballot to connect the state's major urban areas. The project is to be constructed in two major phases. Phase 1, as approved by voters will connect San Francisco and Los Angeles in two hours and 40 minutes. A Phase 2 would extend the system north to Sacramento and south to San Diego, for a total system length of 776 miles (1,249 km). With a top speed of 220 mph (350 km/h), CAHSR trains would be the fastest in the U.S. and among the fastest in the world.
