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 ope |
