The All Aboard Act of 2025 is designed to enhance the United States' rail system through a comprehensive approach that includes establishing grant programs, promoting electrification, and addressing air quality issues. The legislation aims to modernize rail infrastructure, expand passenger services, and support workforce training to ensure these improvements are sustainable and beneficial to communities. A key provision of the act is the creation of a State rail formula grant program, which allocates financial support to states for developing rail plans and improving rail services.
