The distribution of load placements on wagons, i.e. the Centre of Gravity (CoG) of wagons and the distribution of loads between wagons in the train configuration, i.e. train make-up can significantly change the train operational dynamics and, in some circumstances, contribute to derailment of wagons and wheel/rail damage (wear and Rolling Contact Fatigue (RCF)).
In order to reduce derailment risks and wheel/rail damage, the lateral, longitudinal and vertical limits for placing loads on wagons and constraints for the placing of empty or lightly loaded wagons in a consist of loaded wagons should be defined.
The preliminary analysis performed shows that no clear methodology for control of these issues exists in Australia at the present time
The project will utilise train dynamics and vehicle system dynamics simulations to develop a derailment risk and track damage assessment methodology for quick prediction of possible worst operational cases for the investigated train configurations that consider different positions of empty/lightly loaded wagons in a train consist and the CoG for full or partially loaded wagons
