Class 777 CRE Thermal Imaging ISM

This procurement is for the provision of a Conductor Rail Equipment (CRE) monitoring service for the MerseyRail Class 777 fleet.

The service will cover the design, supply, installation, commissioning, and ongoing operation and maintenance of thermal and visual imaging equipment on two Class 777 units, as well as secure provision of processed data and insights.

The CRE monitoring service will provide the following core functionalities:

• Thermal Imaging: Identification of hotspots indicating loose connections, high resistance points, and damaged insulators.
• Visual Monitoring: Forward-facing video to provide context and enable remote inspection of the rail corridor and equipment.
• Automated Alerts: Near real-time detection of potential CRE faults to support proactive and predictive maintenance interventions.

This service will enable Network Rail to identify emerging defects earlier, minimise CRE-related failures, reduce service disruptions and manual trackside inspections, and contribute to a safer and more reliable network.
