In this $119.3 million, 50-month project, RailWorks installed a modern, relay-based signal system and constructed track and enclosures for the new interlocking on the New York City Transit Authority (NYCT) Culver Line between Ditmas Avenue and 4th Avenue stations.
L.K. Comstock rehabilitated the signal system on the existing four-track railroad with two Interlockings and below-grade yard. The project called for a new communications-based train control (CBTC)-ready NYCT signal system design, furnished by Alstom Signaling Co.
L.K. Comstock and RailWorks Transit also performed track reconstruction, civil and electrical work associated with the construction of a two-story relay room building and three new central instrument rooms (CIRs); two located on the mezzanine level and one in the tunnel. Additional work included renovating the existing Church Avenue Tower and Dispatcher’s office. These structures include the latest communications, fiber optic network, security controls, INERGEN® fire protection and associated heating, ventilation and air conditioning (HVAC) equipment systems.
