About Positive Train Control
Known as PTC, Positive Train Control is complex signaling and communications technology that is designed to make rail even safer. This cutting-edge technology has been developed, tested, and installed in rail systems across the country.
Most of PTC can’t be bought “off-the-shelf,” it comes from industry-wide innovation to meet the technical challenges. Many of these components are new technologies being designed and developed for PTC, and railroads must integrate them with their existing systems.
