In modern railway signaling systems, Communication Based Train Control (CBTC) can mainly be used in urban railway lines, either for metro or heavy rail systems. CBTC systems are widely accepted worldwide as they support attainment of optimum capacity, minimize headway and help maintain safety requirements.

The course has been designed such that it covers a comprehensive range of topics related to safety in railway signalling, including theoretical concepts, practical applications, and case studies to enhance understanding and application of the material.
