Amtrak, Gateway Harrison Fourth Track

Amtrak, Gateway Harrison Fourth Track

Project Overview

This project includes the design and construction of approximately 2,000 ft. of additional main track along the Northeast Corridor through the city of Harrison, NJ. This track will be constructed on the northern side of the corridor and require new embankment and retaining structures, track, signals (both Amtrak and PATH), 3rd rail, catenary system modifications, and a relocation of the current westbound PATH track to accommodate the new alignment. The project will also identify any design changes necessary to connect the new track with the existing infrastructure and be coordinated with PATH’s Harrison Station project.

The outcomes of this project will be increased safety and reliability and expanded railway infrastructure to enable the near doubling in train volumes expected in the future.

Envision provided cost estimating and CPM scheduling services for Amtrak’s Design of 4th Rack of Northeast Corridor. Envision was responsible for providing cost estimating services through the conceptual and 30% design phases of this project which entailed Relocation and Installation of New Track, relocation of signal and catenary infrastructure, and removal/replacement of portions of passenger platforms to accommodate this new track within the busy NE Corridor.
