The "American High-Speed Rail Act" aims to significantly bolster the development of high-speed rail corridors across the United States. It authorizes substantial appropriations totaling billions of dollars annually from fiscal years 2027 through 2031 for corridor planning, technology improvements, and development. Specifically, it allocates $3 billion each for planning and technology, and $35 billion for corridor development annually, demonstrating a major federal commitment to expanding rail infrastructure. The bill increases the federal share for high-speed rail corridor planning and development projects to up to 100 percent of costs, while prioritizing projects that secure at least 20 percent of funding from specified non-federal sources. It broadens eligibility for financial assistance to include consortia of public agencies and private entities, fostering greater collaboration. The legislation also introduces a new category, "higher-speed rail" (110-186 mph), allowing up to 20 percent of grants to support these projects alongside traditional high-speed rail (186 mph or more). To expedite project implementation, the Act permits advance acquisition of right-of-way and adjacent real property interests before or during environmental reviews, provided certain safeguards are met. It mandates comprehensive, performance-based safety regulations that promote interoperability within the high-speed rail network. Furthermore, the bill expands project evaluation criteria to include impacts on equity, resilience, sustainability, economic development, and climate , and removes mandatory spending timelines for project costs. The legislation facilitates the acquisition of freight rail right-of-way for high-speed rail projects by allowing rail carriers to sell or lease property and receive grants for acquiring additional property. It also provides tax exclusions for gains from such transactions and related capital improvements. Crucially, the bill clarifies labor protections , deeming operators and certain service providers for federally funded passenger rail as "rail carriers" and "employers" for purposes of the Railroad Retirement Act, Railway Labor Act, and Railroad Unemployment Insurance Act, with specific exceptions for construction contractors.
