The ATSB recommends that the Australian Rail Track Corporation
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 when faults are detected en-route
and operators are advised by the Australian Rail Track
Corporation.
