Description

This Notice of Proposed Rulemaking (NPRM) proposes to amend noise emission regulations to address the unique noise emission characteristics of trains operating at speeds exceeding 160 miles per hour (mph). It establishes an alternative standard for noise emissions from trains exceeding 160 mph up to 220 mph and introduces a special approval process for trains exceeding 220 mph. The proposal aims to remove regulatory barriers for high-speed rail operations while maintaining public health protections. Existing noise limits for trains up to 160 mph will continue to apply and remain available for compliance at higher speeds.
