Which regulatory body oversees rail transport in the U.S.?

The Federal Railroad Administration (FRA) is the regulatory body responsible for overseeing rail transport in the United States. It is part of the U.S. Department of Transportation and plays a crucial role in ensuring the safety, efficiency, and reliability of the nation's railroads. The FRA formulates and enforces regulations regarding railroad safety standards, tracks inspections, and equipment performance. It also conducts research and provides funding for improvements to the rail system.

While other agencies like the Transportation Security Administration deal with security aspects of transportation, and the Environmental Protection Agency focuses on environmental regulations, they do not specifically oversee rail transport. The Federal Rail Enforcement Bureau is not a recognized entity in the structure of U.S. rail regulation, making the FRA the clear authority in this area.
