The NYCT Signals and Train Control Program is a major capital initiative focused on modernizing New York City’s subway signal and train control systems to improve safety, reliability, capacity, and operational efficiency. The program includes the implementation of advanced technologies such as Communications-Based Train Control (CBTC), Automatic Train Supervision (ATS), and Solid State Interlocking (SSI) across multiple subway lines. Delivered within an active transit environment, the work involves extensive construction oversight, system integration, testing, and quality management to ensure new infrastructure meets performance requirements and supports the long-term modernization of the transit network
