Transportation Secretary Sean Duffy announced a proposal to deregulate certain noise pollution standards for trains as part of efforts to facilitate the development of high-speed rail in the United States. The proposed rule, announced by the Transportation Department on July 31, 2026, aims to reform noise emissions regulations for trains traveling between 160 and 220 miles per hour.
Currently, there are no high-speed trains in the U.S. that exceed 160 miles per hour, and Duffy indicated that existing noise regulations have hindered infrastructure development. In a statement, he emphasized the administration's commitment to reducing regulatory barriers to attract businesses and investors to collaborate with the U.S. Department of Transportation (USDOT).
The fastest train in the U.S. is Amtrak's NextGen Acela, which operates at speeds up to 160 miles per hour along the northeastern corridor between Washington, D.C., and Boston. This train complies with existing Environmental Protection Agency (EPA) noise pollution standards.
The proposed changes would allow for alternative noise emission rules for high-speed trains, and a special approval process would be established for trains exceeding 220 miles per hour. The Federal Railroad Administration Administrator David Fink noted that current regulations disadvantage trains that produce noise from sources other than their engines, and updating these rules could help overcome obstacles to high-speed rail operations.
Countries such as Japan, France, and China have successfully implemented high-speed maglev trains, which utilize magnetic levitation technology to minimize noise pollution. The Transportation Department anticipates that the proposed reforms could save high-speed rail developers approximately $100 million over the next three decades.
