Electronic Interlocking (EI)
Modernizing railway operations by replacing older relay-based systems with advanced Electronic Interlocking (EI) systems to make train movements safer, faster, and more efficient.
Param Enterprises Private Limited, in collaboration with Siemens Ltd., has been involved in the execution of 100+ Electronic Interlocking (EI) systems for Indian Railways as part of railway infrastructure modernization.
Electronic Interlocking uses advanced software-based logic to control railway signals and train movements, reducing dependence on traditional relay-based systems. This helps improve safety, reliability, operational efficiency, and traffic management, while dramatically reducing operational bottlenecks.
Advantages of Upgrading to EI
Significant Space & Maintenance Reduction
Highly integrated solid-state logic cards eliminate vast relay rooms, cutting down physical wear-and-tear failures, minimizing cable requirements (using OFC), and reducing lifetime maintenance costs.
Scalability & Centralized Control
EI systems can easily integrate with advanced Centralised Traffic Control (CTC) systems, enabling railway controllers to monitor and manage train movements from a single, centralised interface.
