ARTC allowed identified track twist defects to remain in track contrary to network track geometry requirements.
The ATSB is satisfied that the safety action taken by ARTC addresses the safety issue.
ARTC has addressed localised processes and enhanced work management processes for the response to geometry conditions in accordance with ARTC’s Safety Management System. These initiatives are being driven by the implementation of the AMIP (Asset Management Improvement Program) including improving processes around scheduled maintenance, defects, work orders and responding to AK Car track geometry findings.
Also, as an outcome of the AMIP, a new structure was introduced such that Works Planning Managers and Area Planners are now in place to support Provisioning Centre teams in reviewing known conditions and required responses in order to better manage the maintenance and projects activities across the ARTC Network.
