Abstract
Time based track maintenance, in context of rail profile and track geometry, has conventionally been looked as engineering decisions. Current rail track maintenance activities are typically based on use of exceedence thresholds each measurement is compared against a pre-set threshold such that if it exceeds the threshold then maintenance is done on either of rail profile or track geometry. Time based Condition monitoring system can be used to find defects in rail profile or track geometry. Such system helps in identifying trends for effective and efficient condition monitoring of rail track. One such way is an in depth by information analysis of rail profile and track geometry parameters, over the time, thus finding significant correlations, an then reconciling hypothesis correlations with experimental results, among various parameters of both modalities. Such analysis will not only help in understanding, parameters behaviour of each modality but also leads to significant track maintenance productivity gains.
