The California High-Speed Rail Authority has released its Draft 2026 Business Plan for a 60-day public review and comment period, setting out updated cost projections and delivery proposals for the state’s high-speed rail programme.

The estimated cost of delivering Phase 1 of the system, linking San Francisco with Los Angeles and Anaheim, has fallen by 1.7 billion USD. The reduction is attributed to streamlining measures intended to accelerate construction and manage expenditure.

The draft plan outlines proposals to complete the initial operating segment between Merced and Bakersfield, before extending services to larger population centres to generate operating revenue. It also refers to potential private financing, legislative changes and partnerships designed to support long-term funding.

The Draft 2026 Business Plan sets out the path forward: completion of Merced to Bakersfield, expansion to major population centres for revenue positive service, and early asset commercialisation to produce additional revenue to build out high-speed rail. It explains how we build from progress underway, prioritize investments that produce early and durable commercial benefits, and create the conditions for long-term financial strength and private-sector participation as the system expands.

The authority states that the draft plan reflects established international practices in high-speed rail development, including phased delivery and asset commercialisation to support future growth.

The consultation period runs from 28 February to 29 April. Members of the public may submit comments via an online form, by email, by post to the authority’s Sacramento headquarters, or in person during the public comment section of the board’s meeting on 4 March 2026.

Meanwhile, construction activity continues across the Central Valley. 171 miles of the route between Merced and Bakersfield are under design or construction. Nearly 80 miles of guideway have been completed, alongside almost 60 major structures, with a further 29 structures currently under way in Madera, Fresno, Kings and Tulare counties.
