This is a microprocessor-based safety-critical signalling subsystem for the safety of train operations, that works by controlling the set of signalling gears that prevents trains from conflicting movements, and by allowing trains to receive authority to proceed when routes have been set, locked, and detected in safe combinations.
Purposes :
- Safety of train operation by controlling a set of signalling gears
Interfaces :
Train Management System / Centralized Traffic Control
Level Crossing System
Central Maintenance Terminal Console / Diagnostic System
Features :
Certified for Safety Integrity Level CENELEC SIL 4
Enhanced or Improved System Capacity
System is approved by the respective safety and certification agencies of multiple countries including India (RDSO)
