California’s rail agencies have signed a new agreement to coordinate environmental work, design and station integration for the Palmdale high-speed rail connection to Victor Valley.

Agreement centers on Palmdale Station

The California High-Speed Rail Authority⁠ announced the memorandum of understanding on July 20. It commits the Authority and the High Desert Corridor Joint Powers Agency to closer coordination of environmental clearances, station integration and design, particularly where the planned systems would meet at Palmdale Station.

The agreement also provides for coordination on construction activities and joint purchases of materials. The agencies say those steps are intended to reduce public costs and accelerate delivery, but the MOU is a planning and coordination instrument rather than a construction authorization.

The High Desert Corridor JPA represents Los Angeles County, LA Metro, Palmdale, Lancaster, Adelanto and Victorville. It leads the planned rail corridor between the Antelope Valley and Victor Valley.

A 54-mile link to Victor Valley

The proposed High Desert Corridor⁠ would run 54 miles from Palmdale to Victorville. Preliminary concepts call for a dedicated double-track railway designed for speeds up to 180 mph, with grade separations and structures across roads, highways and desert washes.

At Palmdale, the corridor would connect with California’s statewide high-speed rail system. At Victor Valley, it would link to Brightline West, providing a future rail connection toward Rancho Cucamonga and Las Vegas.

The High Desert Corridor JPA⁠ says the project is undergoing a federal environmental reexamination of its 2016 environmental impact statement, with a Record of Decision targeted for late 2026 or early 2027. Preliminary engineering, surveys, geotechnical borings and utility coordination are listed as subsequent milestones.

Central Valley work moves toward rail systems

Meanwhile, major sections from Merced to Bakersfield remain under design and construction. Nearly 90 miles of guideway and 61 major structures are complete, while 30 more structures are underway across Madera, Fresno, Kings and Tulare counties.

The statewide Phase 1 system is planned for 494 miles between San Francisco and Los Angeles/Anaheim, of which 463 miles are environmentally cleared and construction-ready. The Authority is preparing to begin track, electrification and systems installation in the Central Valley later in 2026.
