New cable racking system with fire-resistant cables: The rehabilitation plan uses a racking system to suspend fire-resistant cables on the side of the tunnel rather than buried inside a concrete bench wall, making cables easier to maintain and upgrade and decreasing potential for damage from flooding.
New wall structure with industrial fiber-reinforced polymer (FRP): This material, used to carry heavy loads of bridges in transit projects worldwide, was used to create a new wall structure along the tunnel, creating structured panels which are installed to wrap around the damaged bench wall.
New tracks, including new plates and continuous welded rail: 6,305 track feet have been installed, including new track ties, using continuous welded rail - allows trains to safely operate at faster speeds and reduces wear and tear of car equipment and the associated maintenance costs.
New discharge lines, pipes and controls: The pumping system has been upgraded to handle even greater flooding from potential natural disasters - more than doubles the water pumping capacity.
New fiber optic monitoring system is being calibrated: 7,000 feet of specialized hydro- and geo-sensing fiber optic cables have been installed in the first tube. The system will automatically process and transmit data and any alerts directly to the NYCT rail control center.
