NEW YORK CITY – Phase three of MTA’s signal modernization work on the G Line will begin on Monday, August 12th and continue through September 3rd.
During this time, there will be no G train service between Bedford-Nostrand Avs and Church Av. Riders can information regarding shuttle services at MTA’s website here.
The signal system dates back to the 1930s and will be modernized with communications-based train control (CBTC). The MTA says this will make the service more reliable for its customers. Once this project is completed, the G Line will be the third in its subway system that has been fully converted to the CBTC, joining the L and the 7. Phase 3 will start with replacing curved track. This area between Bergen St and Hoyt St has seen wear and tear due to trains making sharp turns.
Phase 1 and 2 saw the “complete reconstruction of the train interlocking between 21st Street and Court Sq.” The new interlocking includes 3,000 feet of new third rail and more than 50 miles of new cables that support a fiber optic and wireless communications system. Additionally, the MTA reports crews have added a “new track lubrication infrastructure” for noise reduction. All three of the project’s phases include implementing modern composite ties so as to be more water resilient than traditional wooden ties.
Below is a video from the MTA showing crews working on the G Line Signal Modernization Project:
“We’re transforming the subway with a modern signal system that will deliver faster and more reliable service for generations to come,” said MTA Chair and CEO Janno Lieber. “I’m proud of the successful shuttle bus operation New York City Transit has delivered to keep train customers moving throughout the duration of this project.”
“We appreciate customers’ understanding as we work to modernize a signal system that dates back to the FDR administration,” said MTA Construction & Development President Jamie Torres-Springer. “And we’re delivering this project better, faster and cheaper with phased outages that ensure we get this critical work finished as efficiently as possible.”
