Improving alignment design through the early integration of train performance simulation

On project applications, train performance simulation modelling is commonly used as a tool to validate an established rail alignment design. The application of performance modelling in this way does not fully exploit the benefits of performance modelling as an aid to alignment design. This paper explores what benefits can be gained by integration of performance modelling into the early rail alignment design process. Jacobs SKM recently designed options for a 150 kilometre heavy haul rail line as part of the Central Eyre Iron Project definitive feasibility study. Performance modelling was incorporated early in the design process which resulted in improvements in the alignment which may have otherwise been missed. Based on this experience, it is proposed that conducting performance modelling in parallel to the alignment design process in an iterative process can improve both designer efficiency and the final design.
