Los Angeles to San Diego

As the high-speed rail system grows to include the entire Phase 1 service, opportunities will exist to extend the benefits of Phase 1 service into Phase 2 corridors such as Los Angeles to San Diego via the Inland Empire. This project section is approximately 167 miles long.

Corridor planning is helping to prioritize the timing and type of investments necessary to extend the Phase 1 system. Near term service improvements to Metrolink, Amtrak Pacific Surfliner and Coaster services will be identified, while also laying the groundwork for full Phase 2 high-speed rail service in the future.  In conjunction with Statewide Rail Modernization, Planning, and Integration efforts the Authority and the Inland Corridor Group have been working to define the southern Phase 2 corridor.

High-speed rail has undertaken a technical planning study in close coordination with local agencies that is focused on developing strategies for how high-speed rail will be implemented in the project section, including prioritizing locations for advancing enhanced connections to the Phase 1 system, early blended service, phasing, opportunities for right-of-way preservation and approaches for environmental clearance, partnerships and funding, and next steps to move the project forward.
