SACRAMENTO, June 2026 — The California High-Speed Rail Authority (CHSRA) has approved the award of a US$3.5 billion contract covering trackwork, electrification and railway systems for the Central Valley high-speed rail corridor. The contract marks the project's transition from large-scale civil works to the installation of core railway infrastructure required for future passenger operations.
The contract was awarded to the Dragados-Flatiron Joint Venture and encompasses the design and installation of track, overhead electrification, signalling, communications and associated railway systems along the initial operating segment between Merced and Bakersfield. The scope also includes testing and commissioning activities needed to prepare the line for service.
The award represents one of the most significant procurement milestones since construction began in the Central Valley. With major viaducts, grade separations and earthworks already completed or under construction, project delivery is now shifting toward creating a fully functional railway capable of supporting high-speed train operations.
For the rail industry, the contract demonstrates continued progress on North America's largest high-speed rail project despite longstanding scrutiny over costs and timelines. The installation of railway systems is a critical phase that will determine operational readiness, safety certification and future service performance across the corridor.
The development reflects a broader trend among major rail infrastructure projects worldwide, where digital signalling, electrification and integrated systems are becoming central to network delivery. As California advances toward track installation and systems commissioning, the project moves closer to establishing the first dedicated high-speed rail service in the United States.
