New Jersey Transit Positive Train Control (PTC) System – New Jersey, USA
- New Jersey Transit Corporation
Design And Urban Planning, Engineering, Program/Construction Management (PM/CM)
We served as prime contractor and design-builder for the New Jersey Positive Train Control (PTC) System, providing a turnkey system to develop, install, and integrate an interoperable Federal Railroad Administration (FRA) certified PTC system on NJ Transit’s 300+-mile regional commuter rail system.
Delivering The Northeast Corridor’s First Interoperable PTC Systemwide Implementation
This significant contract represented the first of its kind interoperable PTC systemwide implementation to be awarded in the Northeast Corridor area which needed to be interoperable with Amtrak. We managed the overall program and provided design, installation, documentation, testing, integration, commissioning services, construction oversight and warranty. In addition, we led the overall radio frequency infrastructure development, managed the development of the network management system, and provided an interface to the dispatching system.
What Is Positive Train Control (PTC)?
PTC is a collision avoidance technology that monitors and controls train movements. Implementation of PTC technology improves safety for New Jersey Transit’s passengers and workers, as it is capable of preventing train-to-train collisions, over-speed derailments, and movement of a train through a switch in the wrong position.
We are a recognized leader in the application of communications-based train control systems and the technical lead on multiple installations worldwide.
Our certified PTC system is fully interoperable with the Amtrak, NS, and CSX’s PTC systems. NJ Transit’s PTC systemwide implementation program will consist of the following:
- A PTC back-office system (two systems)
- PTC on-board computers, speed display units, Crash Hardened Event Recorders (CHER), GPS tracking, and radios on over 400 cab cars and locomotives
- Stop enforcement system
- Wayside interface to NJ Transit’s signal interlockings
- A systemwide communication network to link the wayside signals, trains, and the centralized dispatch office using the Advanced Civil Speed Enforcement System (ACSES) II compliant 220 MHz radio system and NJ Transit’s backhaul communication infrastructure
Pioneering PTC in the Northeast Corridor
We delivered this PTC system to meet the federal mandate and designed and installed the system while standards and protocols are still in development. Working with Alstom, NJ Transit, and the FRA this project set the standard for the Northeast Corridor.
