Following the collision at Cleveland, Queensland Rail implemented procedures to manage and reduce the incidence of wheel slide events. The procedures applied to rail traffic crew, network control officers, network maintenance staff, rolling stock engineers and rail safety management staff. Research conducted by two universities on wheel/rail contamination and work by the Wheel Rail Interface Working Group prepared a standard for the management of wheel slide events. This standard (Management of Rail Traffic Wheel Slide Events) applies to all Queensland Rail business groups and train operations. All instances of wheel slide on the network are reported and recorded. The new standard requires every wheel slide event greater than 6-cars (about 150 m) to be investigated including analysis of train event recorder information to determine the probable cause.
The ATSB notes that a new standard for the management of wheel slide events has been implemented with respect to recording wheel slide events, but is not yet mature at assessing, reviewing and implementing solutions associated with poor wheel/rail adhesion.
The ATSB is satisfied that the action taken by Queensland Rail will adequately address the safety issue. The ATSB will monitor the progress of the safety action.
