What is the purpose of a train control system?

The purpose of a train control system is primarily to monitor and manage the movement and safety of trains on a track. This system plays a critical role in ensuring the safe and efficient operation of trains by controlling their speed, spacing, and routing. It incorporates various technologies and methods to prevent collisions, manage track occupancy, and ensure that trains follow prescribed schedules. By maintaining communication with the trains and trackside infrastructure, a train control system enables real-time decision-making that maximizes safety and efficiency on the rail network. Thus, the correct answer emphasizes the system's fundamental role in operational safety and coordination, which is essential for all rail operations.
