Our OHE diagnostics systems ensure reliable power delivery to trains by continuously assessing overhead equipment health.

Key OHE Monitoring Technologies:

• OHE Position and Wear Measurement System
  High-speed laser and image sensors measure wire height, stagger, wear, and contact surface, supporting safe pantograph-wire interactions.
• Instrumented Pantograph
  Equipped with precision load cells and accelerometers, this system records dynamic contact forces and pantograph acceleration to identify excessive forces, bounce, or loss of contact.
• Rear Window Recording System
  Captures panoramic high-resolution video of the OHE and surrounding infrastructure for review and post-run analysis.
• GSM-R Based Real-Time Data Transmission
  Enables seamless wireless data transfer of measurement and inspection data to maintenance teams for quick response and predictive maintenance.

Benefits of Our Onboard Diagnostics:

• Continuous, real-time condition monitoring of both track and OHE
• Early detection of infrastructure anomalies
• Reduced manual inspections and associated downtime
• Improved safety and ride comfort through predictive maintenance
• Actionable data for asset managers and planners to optimise track and OHE maintenance cycles
