How Does Positive Train Control (PTC) Work?

Widespread deployment of new technologies like Positive Train Control (PTC) — strategically designed to address human error — will open the door to an exciting new era of safety and efficiency improvement for U.S. freight railroads. Developing PTC from scratch has been a significant undertaking. Thanks to the relentless dedication of freight rail employees, Class I railroads successfully met the congressionally mandated deadline to have PTC fully operable by the end of 2020. Today, PTC is fully implemented and in operation on 100% of Class I PTC route-miles network-wide.
