On Train / Judicial Data Recorders (JRU / OTDR)
On-Train / Judicial Data Recorders (OTDR/JDR) are tamper-resistant monitoring and recording systems designed to capture, store, and protect critical operational and safety data from tram and rail vehicles.
The system continuously records key parameters such as speed, braking commands, traction status, driver inputs, safety system activations, and selected environmental or video data. In the event of an incident, the recorded data provides an objective, time-synchronised record to support incident investigation, regulatory compliance, and operational improvement.

Operational Challenges
Following incidents or operational events, operators face:
• Limited objective data for incident investigation
• Challenges demonstrating regulatory and legal compliance
• Difficulty identifying systemic operational trends
• Prolonged investigation timelines
The absence of reliable recorded data increases risk and uncertainty.
Operational Benefits
Secure data recording systems provide:
• Objective, time-synchronised event reconstruction
• Faster, more accurate incident investigations
• Improved regulatory and legal confidence
