Title: TRACK MAINTENANCE PLANNING USING COMPUTER ANALYSIS
Abstract: Planning track maintenance in a railroad system requires the accurate measurement of track condition and the definition of its relationship to the various system costs. The Track Management model has been developed by BHP Research - Melbourne Laboratories for use by heavy haul railroads. The model calculates recommended maintenance cycles and associated operating costs and determines the cost-effective track condition in terms of the weighted Track Quality Index (TQI). The TQI was developed by BHPR-ML to indicate the track quality in terms of the effect of various track geometry parameters on damage-related costs. Sensitivity analyses on the model have indicated that the TQI degradation rate, in terms of variation with gross tonnage, has the most significant effect on the model output, followed by the efficiency of the tamping and lining operation. Other parameters such as curve radius, axle load and allowable head loss limits have also been examined.
