Our work with our supply chain partners to minimise coal dust by utilising a combination of veneering, improved wagon loading practices and monitoring systems, has resulted in a reduction of coal dust by up to 75%*.

We actively assess and implement dust management practices and customised these to suit the particular needs of each of the rail systems where we operate.
In Queensland, we have led the development of two Coal Dust Management Plans for the South West System and Central Queensland Coal Network. The plans provide a thorough analysis, supported by scientific evidence, of the impacts associated with coal dust in addition to identifying leading practices to managing and reducing these impacts.
In the Hunter Valley, we are working with our coal supply chain partners to conduct studies to determine further opportunities to reduce coal dust as part of the Hunter Rail Corridor Users and Operators Group. We are also an industry representative on the Lower Hunter Reference Group (LHR Group).
We have made improvements based on scientific studies, including a wind tunnel testing report on Hunter Valley coal types. Interim data released by the LHR Group also shows coal dust levels well below the NSW EPA acceptable level of deposited dust. The LHR Group will report on its final conclusions shortly.

We have worked continuously to address the management of coal loss from wagons by improving its design. The design includes features that reduce coal loss during loading, unloading, and transit as illustrated on the right.
We also have introduced design features that reduce coal hang up on wagons allowing coal to be shed from the wagon at the loading and unloading points.
We will continue to invest in ongoing research and development of innovative design solutions for coal wagons to minimise coal loss in transit.
