Find your country's enquiry point on WTO ePing (opens in a new tab)Notice of proposed rulemaking (NPRM); request for comments - This NPRM seeks to amend the noise emission regulations to address the unique noise emission characteristics of trains operating at speeds exceeding 160 miles per hour (mph). Specifically, the proposed regulation would provide an alternative standard for noise emissions from train operations exceeding 160 mph, up to 220 mph, and also provide a special approval process for noise emissions from train operations exceeding 220 mph. This alternative noise emission standard and compliance process would effectively remove an existing regulatory barrier to the railroad industry for high-speed rail operations, while continuing to protect public health and welfare. Existing noise emission limits for all train operations at speeds up to 160 mph would continue to apply, and these existing limits would remain available for demonstrating compliance at higher speeds as well.
