SYSTRA and TYPSA design track for the Merced-Bakersfield rail line

Several European construction and engineering firms are involved in the Central Valley segment (Merced-Bakersfield) currently under construction: Spain's Ferrovial Agroman formed the "California Rail Builders" JV with Griffith Company and Spanish engineering firm Euroestudios for Construction Package 4 (design-build, 22 miles, Kern County, ~$442 million). Spain's ACS subsidiary Dragados partnered in the Dragados/Flatiron/Shimmick JV for Construction Package 2-3 (65 miles). In June 2024, a joint venture of France's SYSTRA and Spain's TYPSA was awarded a contract worth up to $131.2 million to design track and overhead contact systems for the full 171-mile Merced-to-Bakersfield route.

California's high-speed rail project is under construction in the Central Valley segment (Merced-Bakersfield), with completion no earlier than 2030-2033; the overall network is planned to eventually connect San José and Los Angeles. Several European firms are documented as construction and design partners: Ferrovial Agroman/Euroestudios (Spain) for Construction Package 4, Dragados/ACS (Spain) for Construction Package 2-3, and SYSTRA (France) together with TYPSA (Spain) for track and overhead-line design across the full 171-mile segment.
