1. Position of RBC Within the Overall System
The RBC (Radio Block Center) is a core train control system that monitors the position and speed of trains via wireless communication, and grants movement authority to ensure safe operation.
It plays a central role in managing real-time train traffic within the communication-based signaling architecture.

Level Transition
This function ensures the train safely transitions between different signaling systems or control modes, switching to the appropriate KTCS level as it enters a new section.
Movement Authority (MA)
Defines the safe operational section for a train. The RBC provides the MA to the train via wireless communication, ensuring controlled and secure movement.
Emergency Brake (EB)
The emergency stop function enables forced braking of a specific train or all trains without conditions or validations. It is triggered in critical danger scenarios to immediately halt train movement.
Handover
The handover function enables the seamless transfer of control between RBCs as the train moves from one RBC's jurisdiction into another, maintaining continuous safety and communication.

Train Control – ATO
(Automatic Train Operation)
ATO (Automatic Train Operation) is a system that enables trains to operate automatically based on predefined data.
It calculates the optimal speed profile to ensure precise stopping at stations within scheduled arrival times,
offering high energy efficiency and improved operational accuracy.
Block Schematic
Automatic Departure and Precise Stop Control
Ensures the train departs and stops at the exact designated location on the platform through automated control logic.
Automatic Acceleration and Deceleration
Provides trains with real-time Journey Profile (arrival time data) and Segment Profile (trackside condition data), allowing optimized speed control for energy-efficient operation.

Signal Violation Prevention System
SVPS
When a train operated under driver-responsible mode violates a stop signal, SVPS immediately issues a warning to the driver and activates the emergency brake. In addition, it automatically halts nearby trains to prevent secondary collisions, significantly enhancing overall operational safety.
