On 1 July 2001, loaded coal train EG37 derailed on Connors Range causing $A21M damage to rolling stock and infrastructure. The accident resulted in the derailment of 75 wagons and 2 electric locomotives and extensive damage to about 500 metres of track and overhead wiring. There were no injuries resulting from the accident.

The investigation into the accident determined that an extended loss of Locotrol radio signal at the top of the range and the failure of the back up safety mechanism in the train brake system triggered the event. The brake system failure was due to a stray O-ring lodged in the seat of the cut off portion of the Brake Pipe Control Valve. The braking of the train was consequently reduced to something less than half its normal capacity. This was insufficient to allow the driver to control the speed of the train down the range.

Queensland Transport acknowledges the efforts of the ATSB for chairing the panel and Queensland Rail for their professionalism and unlimited provision of technical expertise.
