Context:
-
The Indian Railways’ indigenously developed Kavach Automatic Train Protection (ATP) system, planned for the high-density Mumbai–Delhi–Kolkata routes, has faced another deadline extension.
-
The system is now expected to become operational only by 2026, after missing earlier targets.
Key Highlights:
Government Initiative / Policy Details
-
Kavach is a flagship railway safety initiative aimed at preventing accidents through automatic braking intervention.
-
The Ministry of Railways initially targeted completion by March 2025, later revised to December 2025, and now extended further.
Implementation Status & Progress
-
Around 25% of installation work on the Mumbai–Delhi–Kolkata corridors has been commissioned.
-
Kavach Version 4.0 commissioned successfully on 738 route km, including:
-
Palwal–Mathura–Nagda section
-
Howrah–Bardhaman section
-
Infrastructure Development
-
Optical fiber cable laid across 7,129 km
-
Around 800 telecom towers installed for communication support
Stakeholders Involved
-
Ministry of Railways
-
Indian Railways safety and signaling divisions
-
Loco pilots and station authorities
Significance / Concerns
-
Delays show challenges in deploying a technology-intensive safety system across India’s vast rail network.
-
Timely implementation is crucial for reducing collisions and improving passenger safety.
Relevant Prelims Points:
-
Kavach is an indigenous Automatic Train Protection (ATP) system.
