![]() ![]() In March 2023 the California High-Speed Rail Peer Review Group raised some significant concerns about the project's continued viability. The implementation of the project has been controversial due to its selected route, management, delays in land acquisition and construction, cost over-runs, and inadequate funding for finishing the entire system. ![]() The high-speed rail system is anticipated to provide environmental benefits (reducing pollution and carbon emissions), traffic benefits (improving passenger travel, and reducing vehicular traffic and air travel congestion), and economic benefits (especially in the Central Valley). Once the full Phase 1 system opens, the nonstop trains between San Francisco and Los Angeles – which are about 350 miles (560 km) apart by air – must not exceed 2 hours and 40 minutes travel time. Maximum train speeds will be about 220 miles per hour (350 km/h) in the dedicated HSR segments, and about 110 miles per hour (180 km/h) in the blended segments. Extending the Interim IOS to connect to the northern and southern metropolitan segments is dependent on future funding, so their timing is uncertain. Concurrently, in the major metropolitan areas of San Francisco Bay Area and Greater Los Angeles, the commuter rail systems are being upgraded for improved safety and service, and to support a "blended system" in the future with CAHSR sharing upgraded tracks, power, train control, and stations. It will run from Merced to Bakersfield, and is planned to begin operations in 2030 (or slightly later). The first of the dedicated HSR segments, the Interim Initial Operating Segment ("Interim IOS"), is being constructed now in the San Joaquin Valley portion of California's Central Valley. The CAHSR system is currently being implemented in phased segments. In 2008, voters approved the plan as specified in Proposition 1A, with a route connecting all the major population centers of the state, authorized bonds for beginning implementation, and establishing other requirements. In 1996, the California Legislature and Governor Pete Wilson established the California High-Speed Rail Authority with the task of creating a plan for the system, and then presenting it to the voters of the state for approval. California High-Speed Rail (also known as CAHSR or CHSR) is a publicly funded high-speed rail system currently under construction in California in the United States. ![]()
