This Guideline for Wheel and Rail Profile Development provides  guidance on assessing wheel and rail profiles theoretically and in the field (in service) and provides a change management process for developing, testing and implementing new wheel and/or rail profiles.

This Guideline is applicable to all Australian rail networks, including narrow, standard, and broad-gauge railways.

This guideline is not specifically intended to cover light rail networks that may have different requirements; however, could be applied if deemed appropriate by the relevant light rail manager.

The influence on wheel profile wear due to braking forces applied to the wheel via brake shoes is not considered within the scope of this guideline.
