FRA Proposes New Noise Rules for High-Speed Trains

USA: FRA has proposed new high-speed train noise rules for operations above 160 mph, while FTA is offering $22 million for transit safety, accessibility and technology projects.

The two federal actions address different parts of passenger transportation. The rail measure is a proposed regulation rather than a rule already in force, while the transit funding is available through two competitive grant programs.

Proposed standard addresses aerodynamic noise

The Federal Railroad Administration proposal would amend 49 CFR Part 210 to reflect how the main sources of train noise change at very high speeds. Mechanical and rolling noise generally dominate at lower speeds, but airflow around the train becomes the leading contributor above 160 mph.

For operations exceeding 160 mph and up to 220 mph, FRA proposes an optional alternative compliance standard based on total pass-by noise. The baseline would be 96 dB(A) at 160 mph, measured 25 feet from the track, with higher limits allowed as speed increases. Operators could still use the existing federal standards instead.

Systems exceeding 220 mph, including magnetic levitation technology, would receive a special approval pathway. Existing requirements would continue to govern trains operating at up to 160 mph. FRA says no US train currently operates above that threshold; the country’s fastest trains now have a maximum operating speed of 150 mph.

USDOT estimates the proposal could produce approximately $100 million in benefits for high-speed rail developers over 30 years by avoiding some equipment modifications. The estimate depends on the proposal becoming final. The public comment period will run for 60 days after publication in the Federal Register.

FTA divides $22 million between two programs

Separately, the Federal Transit Administration is offering approximately $12 million through the Innovative Coordinated Access and Mobility program. ICAM funds capital projects that coordinate public transportation with non-emergency medical transportation for disadvantaged populations. Applications are due September 9, 2026.

Another $10 million is available through the Bus Safety, Accessibility and Innovation Research Program. It supports research and prototypes for safer bus designs, improved operator protection, passenger accessibility and technology that can be retrofitted to existing vehicles or installed on new buses. Applications close September 28, 2026.

FTA also identifies contactless fare payment, improved scheduling for riders with accessibility impairments, family-friendly vehicles and maintenance facilities among the eligible areas. The rail proposal and grant competitions now move on separate tracks: FRA must complete rulemaking, while FTA will evaluate applications after the two September deadlines.
