At approximately 2310 on 28 September 2017, the driver of train 9T90 noticed sparks coming from the rear of the train. After stopping the train near Kimburra to investigate, the driver identified a broken axle on the sixteenth wagon. This was reported to the network control officer in Townsville who then arranged the appropriate recovery response.
There were no injuries or reported sulphuric acid product spill. The track and rolling stock sustained minor damage.
The ATSB has commenced an investigation and is collecting relevant evidence, including metallurgical examination of the failed axle and interviews with directly involved parties. The evidence will be analysed and a draft investigation report compiled. This draft report will be forwarded to relevant parties for comment prior to the completion and release of the final report.
