Speno has undertaken safety actions to improve the effectiveness of its ultrasonic inspection of rail at unsealed level crossings. Capability improvements include the introduction of procedures for the identification of corroded rail at level crossings, and associated staff training. Specific procedural inclusions to enhance detection of deteriorated rail include:
- A reduced test vehicle speed of five km/h for testing at level crossings
- Criteria and protocol for re-inspection in the case of any identified discontinuities
- Criteria and protocol for follow-up hand testing and engineering inspection
- Enhanced reporting requirements.
