I. Indian Railways have prepared a National Rail Plan (NRP) to create a ‘future ready’ railway system by 2028.
II. ‘Kavach’ is an Automatic Train Protection system developed in collaboration with Germany.
III. ‘Kavach’ system consists of RFID tags fitted on track in station section.
Which of the statements given above are not correct?
Explanation
Statement 1 is incorrect: The National Rail Plan aims to create a ‘future ready’ railway system by 2030, not 2028. The objective of the Plan is to create capacity ahead of demand, which in turn would also cater to future growth in demand right up to 2050 and also increase the modal share of Railways to 45% in freight traffic and to continue to sustain it.
Statement 2 is incorrect: ‘Kavach’ is an indigenously developed Automatic Train Protection (ATP) system by Indian Railways, not in collaboration with Germany. The name "Kavach," meaning "shield" in Hindi, reflects its purpose of delivering robust protection and upholding top safety standards in railway operations. With its certification at the highly regarded Safety Integrity Level 4 (SIL-4), Kavach demonstrates outstanding reliability.
Statement 3 is correct: Radio Frequency Identification (RFID) tags are placed throughout the entire track length to enable the Kavach system to track train positions and detect any potential safety issues along the route.
Automatic Train Protection (ATP) is a train safety system designed to ensure that a train’s speed remains within the limits set by the signalling system. It continuously monitors the train’s speed and automatically enforces compliance with permitted speed restrictions. If the train exceeds the allowed speed or fails to respond to specific signal aspects, ATP promptly activates the emergency brakes to bring the train to a stop. Tolerable Hazard Rate (THR) and Safety Integrity Levels (SIL):
The Tolerable Hazard Rate (THR) acts as a benchmark for evaluating safety-related failures. THR evaluates both systematic and random safety-related failures within a system. It establishes a quantitative framework to define the required safety level, ensuring compliance with acceptable risk standards. Safety integrity is classified into four tiers, ranging from SIL 4 (highest safety assurance) to SIL 0 (no mandated safety measures). A Safety Integrity Level (SIL) is determined through a qualitative review of factors such as safety protocols, quality management systems, and technical safeguards. Attaining the correct SIL is crucial for mitigating risks posed by systematic flaws and random operational failures.
