Indian Railways Sanctions ₹432 Crore Electronic Interlocking Project

Synopsis: Indian Railways sanctions a ₹432 crore electronic interlocking project for Eastern Railway to modernise signalling systems. The upgrade aims to improve safety, reliability, and operational efficiency on busy routes.

Indian Railways sanctions a ₹432 crore Electronic Interlocking (EI) project for the Eastern Railway zone as part of its ongoing efforts to modernise railway signalling infrastructure. The initiative aims to enhance passenger safety, improve operational efficiency, and strengthen the reliability of train movement across high-density routes.

The project focuses on replacing older relay-based interlocking systems with advanced electronic signalling technology. Electronic Interlocking systems use computer-based controls to manage train routes, signals, and movements with greater accuracy, reducing the chances of signalling failures and improving overall network performance.

The modernisation initiative covers important locations on Eastern Railway routes that handle significant passenger and freight traffic. The upgrade is expected to improve train operations by enabling faster fault detection, quicker restoration of services, and better management of railway traffic.

The move is part of Indian Railways’ broader strategy to transform its signalling ecosystem through technology-driven solutions. Existing relay-based systems on several routes have been operating for decades and require higher maintenance due to ageing equipment and outdated components.

Electronic Interlocking provides improved safety by ensuring that train routes are set correctly before movement is authorised. The system enables precise monitoring and control of signalling operations, supporting smoother train flow and reducing operational disruptions.

The project also supports Indian Railways’ preparations for the adoption of advanced technologies such as the indigenous Automatic Train Protection system, Kavach, Automatic Block Signalling, and Centralised Traffic Control. These technologies are designed to improve safety standards and increase railway capacity.

Eastern Railway is among the important railway zones handling large volumes of passenger and freight movement. Strengthening its signalling infrastructure is expected to support more efficient operations and improve reliability across critical corridors.

The initiative aligns with Indian Railways’ larger modernisation programme, which focuses on improving infrastructure, enhancing safety, and using digital technologies to upgrade railway services. Signalling upgrades remain a key priority as train traffic continues to increase across the network.

The investment in Electronic Interlocking is expected to benefit both passenger and freight services by enabling smoother scheduling, reducing delays caused by signalling issues, and improving capacity utilisation on busy routes. The project will contribute to a more efficient and technology-enabled railway system.

With this signalling upgrade, Indian Railways continues to advance its vision of creating a safer, smarter, and more reliable transportation network. The Eastern Railway project represents another step towards building a modern railway infrastructure capable of meeting future mobility requirements.
