Issue number: RO-2014-012-SI-01
Who it affects: All rail infrastructure managers
Issue owner: Genesee Wyoming Australia (GWA)
Operation affected: Rail: Infrastructure
Background: Investigation Report RO-2014-012

Safety issue description

GWA had no documented system in place to assess the suitability of second-hand components for re-use.

Proactive Action

Action organisation: Genesee Wyoming Australia (GWA)
Action number: RO-2014-012-NSA-017
Date: 28 April 2015
Action status: Closed

To mitigate the likelihood of a similar derailment, GWA conducted an inspection of all mainline fishplated joints to ensure structural integrity of each join and have since removed all the joints through a welding program.

In addition to the welding program, GWA completed an organisational audit and review of maintenance standards and processes. This review included the contracted maintainer (Transfield Services Australia), and targeted:

  • inspection of used fishplates prior to installation
  • removal of fishplates with flame cut bolt holes from service
  • improving the training of track inspectors with respect to monitoring and maintaining mechanical joints the accurate recording of the derailment risks attributable to the activities carried out by track maintenance staff
  • track standards to determine what constitutes a temporary joint along with track speeds and the inspection frequencies that should apply.

Through their own investigation GWA identified the degradation of the track substructure as a contributor to the derailment of 24KW. In cooperation with Arrium Iron Ore they are currently completing a study into the track substructure in the section between Iron Baron and 21km Junction and have engaged a subject matter expert to manage this process.

   
Current issue status: Adequately addressed
Status justification:

The ATSB is satisfied that the actions taken by GWA will adequately address this safety issue.
