Positive Train Control (PTC) is a system designed to prevent train-to-train collisions, derailments caused by excessive speeds, unauthorized train movements in work zones, and the movement of trains through switches left in the wrong position. PTC networks enable real-time information sharing between trains, rail wayside devices, and “back office” applications, regarding train movement, speed restrictions, train position and speed, and the state of signal and switch devices.
The Rail Safety Improvement Act (RSIA), which was enacted on October 16, 2008, and the corresponding regulations issued by the Federal Railroad Administration (FRA) require passenger and major freight railroads to implement PTC on most major track lines by December 31, 2015. The National Transportation Safety Board (NTSB) has named PTC as one of its "most-wanted" initiatives for national transportation safety.
Positive Train Control (PTC) and Compliance with Historic and Environmental Statutes
The systems deployed by railroads to implement Positive Train Control (PTC) may require new infrastructure to be built. In certain circumstances, new infrastructure projects must be reviewed for compliance with the historic and environmental statutes. For more information about the review process, please go to the FCC’s tower and antenna siting website.
