Quick Revision: AI-powered surveillance at non-interlocked level crossings uses real-time CCTV feeds and automated alerts to verify gate closure, addressing human error risks in manual monitoring systems.

Why is this in the news?

The Indian Railways is deploying AI-powered surveillance cameras at non-interlocked level crossings to mitigate the risk of accidents caused by gates remaining open. This initiative follows a fatal accident in Tamil Nadu’s Cuddalore district in July 2025, where a train collided with a school van at a manned level crossing, allegedly due to a gate being left open despite the gateman’s confirmation of closure. The AI-enabled system will provide real-time monitoring and automated alerts to railway officials, addressing a critical safety gap in the existing monitoring framework.

Background

• Level crossings in India are classified as interlocked or non-interlocked based on the presence of a mechanical or electrical interlocking system that synchronises gate operation with train movement.
• Non-interlocked level crossings rely on manual operation by gatemen, who are required to close and lock the gate and confirm closure to the Station Master via a private number (PN) exchange.
• The Cuddalore accident (July 2025) highlighted systemic vulnerabilities in manual confirmation processes, where human error or miscommunication led to a gate remaining open despite the gateman’s claim of closure.
• The Railway Board issued directives in 2025 for the installation of CCTV cameras at all non-interlocked level crossings to enhance oversight and accountability.
• The deployment of AI-powered cameras aligns with broader efforts to integrate digital technologies in railway safety, including the use of IoT and machine learning for predictive maintenance and real-time monitoring.

What are AI-powered surveillance systems for non-interlocked level crossings?

• AI-powered cameras are advanced CCTV systems equipped with computer vision algorithms to detect and analyse the status of level crossing gates in real time.
• The system provides live video feeds directly to the Station Master of the nearest railway station and the engineering control room, enabling direct visual verification of gate closure.
• AI algorithms are programmed to generate automated alerts if a gate remains open beyond a predefined threshold or fails to close within the required timeframe, reducing reliance on manual confirmation.
• The cameras are solar-powered, ensuring operational continuity in remote or power-deficient areas, and are designed to withstand harsh environmental conditions.
• Safeguards include accuracy thresholds to minimise false alerts, with human oversight retained for critical decision-making to avoid over-reliance on automation.
• The system complements existing safety protocols, such as the private number (PN) exchange, by providing an additional layer of verification and accountability.
• Implementation is prioritised at non-interlocked crossings due to their higher accident risk, where manual processes are more prone to human error or miscommunication.
• The initiative is part of a broader digital transformation in Indian Railways, aimed at enhancing safety, efficiency, and transparency in operations.
