Summary

FRA is supporting deployment of advanced signal and train control technology to improve the safety, security, and efficiency of freight, intercity passenger, and commuter rail service through regulatory reform, technology development, implementation of Nationwide Differential Global Positioning System (NDGPS), and financial assistance. Positive Train Control (PTC) refers to technology that is capable of preventing train collisions, overspeed derailments, and casualties to roadway workers (e.g., maintenance-of-way workers, bridge workers, signal maintainers) operating within their limits of authority. This technology has the potential capability to limit the consequences of events such as hijackings and runaways that are of special concern in an era of heightened security.
