In April 2013, New York City Transit issued the notice of award to TC Electric for the upgrade of the DC power systems at 207th Maintenance Yard, an $8.5 million project. Work includes replacement of DC feeders to the shop, DC power distribution equipment, a pre-fabricated building, replacement of the trolley distribution systems, and installation of control and alarm systems for improved safety and reliability.
The focus of the 207th St project is to remove and replace the outdated trolley system, which supplies power for trains within the shop during maintenance. As part of the upgrade, a new DC switchgear house was installed atop of the maintenance shop along with the associated switchgear, controls and alarms. The DC positive and negative feeders were also replaced, and the electrical distribution was upgraded in the facility’s Boiler House.
Phasing was critical on this job since all work is done without any outages in yard which operates 24/7. This project was completed ahead of schedule and on budget.
