The ATSB recommends that Pacific National develop and validate a procedure for the use of Bearing Acoustic Monitoring systems. The procedure should include but not be limited to the following:
a) identification of limiting factors and circumstances for the withdrawal of wagons from service when a fault or number of developing fault readings has
been detected
b) formalisation of the actions to make sure that faults detected are acted on in a specified time
c) formalisation of the actions by train crews and others when faults detected enroute are advised by the Australian Rail Track Corporation.
