Safety issue description

The wheel bearings on train 2224, consist BT22, were only being monitored in-service by periodic inspections, roll-bys, and hot box detections. These measures were ineffective in detecting the failure of the bearing on train 2224 before it led to the derailment.

Proactive Action

Action number: RO-2010-001-NSA-008
Action organisation: Pacific National Pty Ltd
Date: 04 July 2011
Action status: Closed

No equipment is on these routes.

It is not economical to put wayside equipment on all corridors. Some trains can be diverted over wayside if it is able to be done so. A program of certain trains running in vicinities of available equipment, has been established to divert trains over some corridors with wayside available.

Additional equipment is being programmed for installation on this corridor, but as mentioned not all PN trains will be able to be captured.

From 31 January 2010, Pacific National began running consist BT22 (and the other similar consists) on special trips through the RailBAM facility at Kingswood in the RailCorp network. Pacific National also advised that additional equipment is being programmed for installation on this corridor

ATSB comment:

The ATSB is satisfied that the action taken by Pacific National adequately addresses the safety issue.
