The ultrasonic testing regime was not effective in consistently identifying corrosion and wasting of the rail web at unsealed level crossings.
The ATSB is satisfied that the action taken by Speno has increased the effectiveness of its ultrasonic inspection of corrosion defects in rail at unsealed level crossings.
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:
