Abstract

The Aurizon (formerly QR National) Workshops in Rockhampton is a large rail heavy maintenance facility where the primary function is to repair and modify rollingstock. As the workshops are in close proximity to the Central Queensland coal fields most of the rollingstock presented are coal wagons and locomotives. Due to the fact that most of the rollingstock in the workshop yard is unpowered an external power source in the form of a rail mounted shunt vehicle is used to place the rollingstock in the desired location. The site has two shunt vehicles, a DN 300 and a DN 100. Both vehicles are designed for on road and on track operation. The on track operation is facilitated by the rubber road tyres contacting the track to provide traction with the on track guidance provided by hi-rail wheels front and rear.

Both machines have derailed during normal operations heightening the risk of possible injury as well as causing major disruptions to production as the machine is quarantined for investigation following a derailment. Management are therefore very keen to try and establish a root cause of these derailments. The focus of this preliminary report is to provide an update on the investigations into the root causes of these derailments.
