Which system primarily governs train movements and ensures safety on designated tracks?

Centralized Traffic Control (CTC) is the system that primarily governs train movements and ensures safety on designated tracks. CTC utilizes a centralized command center that monitors and controls train operations across a network, allowing for efficient scheduling and management of train movements. This system communicates critical information such as track availability, train locations, and signal status to operators, thereby minimizing the risk of collisions and improving overall safety.

By centralizing control, CTC can quickly respond to any changes in train schedules or unexpected incidents, ensuring that trains are routed safely and efficiently. Its design allows for better coordination of multiple trains on the same track, making it a crucial component of modern rail systems.

Other systems, while important in their own contexts, do not primarily govern train movements in the same comprehensive manner that CTC does. For example, the Automated Inspection System is more focused on equipment monitoring rather than direct train control, while the Manual Block System involves more manual oversight and can be less efficient in managing traffic flow. The Locomotive Speed Limiter is designed to control speed but does not manage the broader aspects of train movement and safety oversight that CTC provides.
