The All Aboard Act of 2024 is a comprehensive rail modernization bill that authorizes over $175 billion in federal spending over five years to expand passenger rail service, electrify rail infrastructure, and develop rail workforce capabilities. The legislation establishes a state formula grant program with minimum funding of $10 million per state plus population-based allocations, creates a $50 billion Green Railroads Fund for electrification projects, and provides $80 billion for the Federal-State Intercity Partnership program to build high-performance rail corridors. The bill aims to transition all U.S. locomotives to zero-emission technology by 2047, with interim targets of 50 percent zero-emission trains by 2030 and all new trains by 2035. The legislation also creates two rail workforce training centers, establishes labor protections requiring project labor agreements and prevailing wage standards, and directs the EPA to provide $500 million in grants addressing air pollution from railyards. Eligible recipients include states, Amtrak, public agencies, freight railroads, tribal nations, and labor organizations, with preference given to projects benefiting environmental justice communities and those along high-trafficked intercity corridors.
