Centralized Traffic Control (CTC) is a system used in railways to manage train movements from a central location. It allows operators to monitor and control signals, switches, and train schedules, ensuring safe and efficient train operations. By centralizing these functions, CTC reduces the need for on-site personnel and enhances communication between different parts of the railway network. CTC systems utilize advanced technology, including computers and communication networks, to provide real-time information about train locations and track conditions. This helps in minimizing delays and optimizing the flow of trains, ultimately improving the overall efficiency of the railway system.
