summary: 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.

# High-Speed Train Noise Emission Standards

## TL;DR
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.
