California High-Speed Rail Authority Unveils Draft Environmental Review for LA–Anaheim Segment

Home » California High-Speed Rail Authority Unveils Draft Environmental Review for LA–Anaheim Segment

In a major step toward completing California’s bullet train vision, the California High-Speed Rail Authority (CHSRA) today, December 5, 2025, released the Draft Environmental Impact Report/Environmental Impact Statement (EIR/EIS) for the 30-mile Los Angeles–Anaheim corridor. The move marks a critical milestone in the state’s effort to deliver high-speed rail service to Southern California.

The LA–Anaheim segment, which stretches from Los Angeles Union Station to the Anaheim Regional Transportation Intermodal Center (ARTIC), is the final link in the Phase I route connecting San Francisco to Los Angeles and Anaheim. With today’s release, 100% of Phase I’s nearly 500 miles are now under environmental review or cleared.

Shared Passenger Corridor and Electrification

The preferred design, known as Shared-Passenger-Track Alternative A, proposes two electrified high-speed rail tracks running alongside existing freight and Metrolink service. The project includes the installation of overhead catenary systems, a new light maintenance facility in Vernon, and upgrades to existing passenger stations. While no new stations will be constructed, modifications at LA Union Station and ARTIC will enable seamless high-speed rail operations.

Environmental and Community Impact

According to the Draft EIR/EIS, the project would displace approximately 256 businesses and three homes, mostly in Commerce and Vernon. CHSRA has pledged relocation assistance and mitigation measures to minimize disruption. Environmental benefits include significant reductions in air pollutants and greenhouse gas emissions once service begins.

However, the report also identifies unavoidable visual impacts to historic infrastructure in Downtown Los Angeles, where modern HSR equipment would alter the character of several bridges. Mitigation strategies such as aesthetic design treatments and shielded lighting have been proposed.

A Key Step Toward High-Speed Connectivity

The release of the draft environmental review opens a 45-day public comment period and initiates the final stretch of planning for a corridor that sees daily congestion on both road and rail. With Union Station and ARTIC serving as multi-modal hubs, the LA–Anaheim segment is expected to become a crucial link in California’s statewide mobility network.

When complete, the Los Angeles–Anaheim section will connect directly with the Central Valley HSR spine and future extensions toward San Francisco, promising a dramatic reduction in travel time across the state. Trains will reach speeds of up to 220 mph in dedicated segments, with zero-emission electric service throughout.

Looking Ahead

Construction contracts for LA–Anaheim are expected to be awarded following completion of the final EIR/EIS, anticipated in 2026. With over 463 miles of the Phase I system already environmentally cleared, CHSRA is pushing forward on multiple fronts, including active track and systems procurements in the Central Valley.

Today’s release marks more than just a paperwork milestone—it signals real momentum for a transformative infrastructure project decades in the making.

Public hearings for the LA–Anaheim segment will be held throughout December and January, with community input set to shape the final design. This project is one of the major rail developments currently underway in the United States.
