ARTC advised that on 1 December 2014 it introduced a more structured Asset Management Policy supported by an Annual Works Program that fits within a 10 year Asset Management Plan.
ARTC advised that this new plan includes the annual analysis of rail wear as recorded by the AK Car. Based on further monitoring and predicted rates of deterioration, a 20 year program for rail replacement is developed. The plan for replacement is reviewed each year to validate rail condition and the required time for replacement.
ARTC further advised that this updated rail replacement planning process is supported by on-site verification.
ATSB is satisfied that effective implementation of this policy and plan will address the safety issue.
