The North American Joint Positive Train Control (NAJPTC), was an ambitious project to develop, test, and demonstrate PTC capabilities, including flexible block operations, interoperability, and advance activation of highway grade crossing devices, in a corridor with both freight and passenger service. The projects safety objectives were to: (a) prevent train-to-train collisions (positive train separation), (b) enforce speed restrictions, including civil engineering restrictions and temporary slow orders, and (c) provide protection for roadway workers and their equipment operating under specific authorities. Additionally, the project would provide for industry interoperability, demonstrate safe operation of locomotives equipped with interoperable systems, and implement moving block functionality. The project would provide a cost-effective design in order to enhance prospects for deployment. |
