As North America’s leading rail systems contractor, RailWorks delivers specialized construction and maintenance services exclusively to the rail transportation market. With a long-standing, partner-first approach, RailWorks supports passenger rail and transit agencies, Class I, short line, and regional railroads, as well as industrial operators, ports, utilities, and manufacturers.

RailWorks brings a rich history in track construction and maintenance across all forms of rail travel, combined with proven capability in managing complex, large-scale construction programs throughout the full project lifecycle. From early constructability input and interface planning through construction, systems integration, testing, commissioning, and long-term maintenance, RailWorks applies an end-to-end understanding that supports safe, reliable, and cost-effective transit operations.

Through its L.K. Comstock brand, RailWorks also provides comprehensive transit systems capabilities, including train control, signaling, communications, traction power, AC high- and medium-voltage power distribution, and overhead catenary systems. This integrated track and systems experience enables RailWorks to effectively manage system-wide interfaces, construction sequencing, testing, commissioning, and maintainability—an essential capability for large, technically complex programs such as the California High-Speed Rail Track & Systems Construction Contract (TSCC).

RailWorks averages approximately $1 billion in annual revenue and employs more than 3,500 professionals operating from over 50 facilities across the United States and Canada. In California, RailWorks and L.K. Comstock have delivered—and continue to deliver—some of the largest and most complex transit and rail projects in North America, bringing disciplined program management, systems integration, and a strong safety culture coupled with long-term operations and maintenance experience. This full lifecycle perspective provides delivery certainty and lasting value for the California High-Speed Partners team.
