Signaling systems are configured by onboard signaling, wayside signaling, TTC(Total Traffic Control), performing automatic train protection, automatic train operation, train location detection, restrictive speed control, automatic train control and monitoring. Signaling systems are designed in accordance with the fail-safe principle to ensure safety and reliability of operation of the it’s environment. Major components of the system have redundancy so as to minimize system failures or train suspension due to faults of the system in the process of commercial services.
