  • Integration of microprocessor-based interlocking and axle counters

  • Migration strategies for transitioning from old systems to electronic interlocking

Their ability to implement scalable signalling architectures with rigorous compliance to Indian and international railway standards has made Sensedge a trusted partner in major railway projects across the country.

SAT Testing, Commission, and Control System – Bridging Development and Deployment

A key phase in deploying any railway signalling or automation system is the SAT Testing Commission and Control System, commissioning, and control integration. This phase validates that all systems perform correctly under operational conditions and are ready for safe revenue service.

Sensedge brings unparalleled precision and planning to SAT testing and commissioning processes. Their approach is structured, compliant, and data-driven, ensuring every system is tested against real-world scenarios, stress conditions, and failover events. With specialized test benches and control room integration tools, Sensedge minimizes human error and optimizes the commissioning timeline.

Their offerings include:

  • SAT test case development and execution

  • Automated test environments for interlocking systems

  • Control room interface testing with OCC/SCADA

  • Real-time monitoring and fault diagnostics during commissioning

By streamlining the SAT and commissioning process, Sensedge significantly reduces project deployment timelines and enhances system readiness for Indian Railways.

Interlocking Logic Circuits in Railway Signalling – Engineering Safety at the Core

Interlocking Logic Circuits in Railway Signalling form the critical backbone of railway signalling systems, ensuring that train movements are conflict-free and safely coordinated. As Indian Railways expands and modernizes, the complexity of interlocking circuits has also increased, necessitating smarter, more reliable design and testing methodologies.

Sensedge specializes in the design, simulation, and verification of interlocking logic circuits—both hardware and software based. Their solutions utilize logic simulation tools and formal verification techniques to model train routes, signals, and points with exacting accuracy.

Key capabilities include:

  • Development of safe interlocking logic for electronic interlocking systems

  • Simulation and validation of route locking and point control logic

  • Automated testing of interlocking tables and logic circuits

  • Safety validation using fail-safe principles and redundancy mechanisms

This rigorous process ensures that every signal, switch, and control logic deployed in the field complies with the highest safety norms. Through its innovation in logic simulation, Sensedge enhances operational safety and efficiency in complex track layouts and junctions.

Conclusion: Sensedge – Driving the Future of Safe and Intelligent Railways

As Indian Railways accelerates its journey toward digital transformation and automation, the importance of reliable, safe, and intelligent signalling systems becomes even more vital. Sensedge has emerged as a key enabler of this transformation, offering end-to-end expertise in RAMS management, signalling design, SAT testing, interlocking logic circuits, and system integration.
