  • A. Automatic Train Control
    Automatic Train Control is a railway safety and control system that automates train operations such as speed regulation and braking to prevent collisions and ensure safe, efficient train movement.
  • B. Train Protection & Warning System
    Train Protection & Warning System is a British railway safety system designed to automatically stop or slow trains to prevent collisions and signal passed at danger incidents.
  • C. Automatic Train Supervision
    Automatic Train Supervision is a rail signaling subsystem that monitors, regulates, and optimizes train operations in real time, including scheduling, routing, and service regulation.
  • D. Automatic Train Operation (ATO)
    Automatic Train Operation (ATO) is a railway control system that automates key driving functions such as acceleration, speed regulation, and braking to improve safety, efficiency, and consistency of train operations.
  • E. Communications-Based Train Control
    Communications-Based Train Control is an advanced railway signaling system that uses continuous, high-capacity data communication between trains and track equipment to safely increase line capacity and operational efficiency.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
