Rio Tinto Rail Wagons

Composite reinforcements have successfully extended the operational life of 46 year old rail wagons, targeting a 14 year life extension to end-of-mine life.

All significant fatigue cracking has been eliminated for over 6-7 years in a hot, tropical climate. Long term success has been proven on over 80 rail wagons.

Examples of the carbon fibre reinforcements at each wagon corner are shown below.
