Project Description
This project arose from New Jersey Transit’s desire to increase capacity and flexibility for Hudson-Bergen Light Rail operations. A series of rail upgrades was necessary to accomplish their goal.
An interlocking was created north of the Danforth Station requiring special track work consisting of a double diamond crossover and No. 10 turnout with siding track. A drainage system was installed including reinforced concrete pipe, E-inlets, headwalls and an under-drain. An electrical trough and retaining walls were added. Foundations were constructed for catenaries, signals, snow melters and instrument houses. An existing box culvert was modified and structural fill and final grading concluded the project.
An important feature of this project was our ability to maintain the client’s schedule without significant interruption. Through critical pre-planning and extensive coordination between all parties on site, we were able to perform a majority of the work during weekend outages. All tracks were returned to normal service after each outage and our preparations resulted in the safe and efficient completion of the work.
