California’s bullet train just crossed from earthmoving into railroading. The California High-Speed Rail Authority awarded a roughly $3.5 billion contract on June 4 to a team of Kiewit, Stacey Witbeck and Herzog to install track and the systems that actually run trains across the Central Valley.
It’s the largest single contract the authority has handed out, and it changes the character of the work. For a decade the program has been about viaducts, grade separations and trenches. This package is about the railroad itself.
What the track-and-systems award covers
The scope runs the length of the 171-mile initial operating segment between Merced and Bakersfield. Crews will lay track, string the 25-kV overhead contact system, and install the signaling, train control and communications gear that lets trainsets run at up to 220 mph. All three firms are U.S. contractors with deep rail résumés. Kiewit brings heavy civil and rail experience, Stacey Witbeck specializes in transit trackwork, and Herzog runs rail systems and maintenance across the country.
Why the Central Valley segment matters now
The award ties the program to a concrete deliverable: an operating line, not a string of structures waiting on the next funding cycle. That distinction has dogged the project for years. Critics point to the budget, which has climbed well past early estimates, and to a financing gap the state still hasn’t fully closed.
None of that disappears with one contract. The authority needs billions more before Merced and Bakersfield are linked by moving trains, and the early-2030s target depends on money that isn’t fully in hand. What changed on June 4 is the work in front of crews. Track and systems mean a contractor is now on the hook to make trains run, and that’s a different kind of pressure than pouring another viaduct.
