The All Stations Accessibility Program Reauthorization Act, or ASAP Act, creates a new federal grant program to help states and local governments make older railroad and rail transit systems more accessible to people with disabilities. The bill authorizes $350 million annually starting in fiscal year 2027 for competitive grants that can fund station repairs, accessibility improvements, retrofits, and planning projects at rail systems that were operating before 1990. Recipients of grants must commit to long-term accessibility improvements that serve people with physical, sensory, and intellectual disabilities, while also addressing service equity for low-income riders and communities of color. The federal government will cover up to 80 percent of project costs, with local entities providing the remaining funding. Appropriations will be adjusted annually for inflation, and the bill encourages grant recipients to work with disability advocacy organizations when planning and assessing accessibility improvements.
