NJ Transit, ASES II Positive Train Control

Project Overview

Positive train control (PTC) is collision avoidance technology that monitors and controls train movements. It is intended to prevent train-to-train collisions, over speed derailments, and movement of trains through switches left in the wrong position, as well as prevent train incursions in to work areas. To improve railroad safety in the United States, federal legislation mandates that passenger railroads and large freight railroads (Class I railroads) install positive train control, on all main line track where intercity passenger railroads and commuter railroads operate, as well as on lines carrying hazardous materials.

This project has its unique challenges, including the ability to provide interoperable operations and technology with other operators on the Northeast Corridor. This project also requires design of independent RF systems for commuter and freight operations. NJ Transit has divided the project up into six phases.

Envision was responsible for project document control, including developing and maintaining a Records Management System compatible with the NJ Transit’s Electronic Content Management System (ECMS). Envision assisted with document uploads, development of the Configuration Management Plan, Contract Documents Log, and quality control of all documents to provide an accurate and historical record that can trace decisions made throughout the project’s life cycle.

Envision provided the overall program planning and resource allocation, including review of the implementation schedules, overall program schedule with respect to industry capacity, and NJ Transit’s capacity to support construction, ongoing review of project budget and schedules change orders and claims, and ongoing preparation of cost and schedule trend analysis. In addition, all force account work and hours were tracked in the schedule. The force account activities were required to support the ongoing construction.
