APT (Automatic Passenger Train Control)

APT (Automatic Passenger Train Control) is a safety and management system that automatically regulates train operations to ensure safe, efficient, and timely service. It monitors train speeds, signals, and track conditions, adjusting or restricting train movement as needed. By doing so, APT helps prevent accidents, maintain proper spacing between trains, and optimize schedules without requiring constant manual control. Essentially, it acts as an automated oversight system that helps train operators run trains safely and smoothly, enhancing overall rail network reliability.
