The Signal System Replacement program is a key component to the modernization of PATH. This integrated program will ensure the long-term viability of PATH by bringing it into the 21st Century using the latest technology and continuing to provide customers with reliable and safe service. This new signal system will allow PATH trains to safely run closer together, increasing the number of trains we can fit on the system during peak times. Over the past few years, the Board authorized projects for the replacement of the entire PATH Signal System with a modern Automatic Train Control System (ATC) using communications-based train control technology. PATH staff is diligently working with the Signal Contractor and has currently completed Final Design Reviews.
