“…With reference to the maintenance limits explained in Section 2, Table 2 presents the different geometry states. Owing to the complexity of the degradation process and the maintenance process, predicting the effect of employing different inspection intervals on the track geometry condition is a difficult task (Andrews et al, 2014;Quiroga & Schnieder, 2012). Therefore, the Monte Carlo simulation technique is used to handle the variation of the various parameters within the proposed integrated model and to estimate the percentage of time spent in the different track geometry states.…”

“…The required track condition data can be assessed using both statistical and stochastic track deterioration models. Statistical models based on simple linear (Corbin et al, 1981) and exponential regressions (Quiroga et al, 2011) have been researched widely over the last three decades (Andrade et al, 2016). Stochastic models have also been proposed within different academic literature (Andrews et al, 2013;Zhang et al, 2014), but unlike statistical models, they have not been adopted widely within the railway industry.…”

“…Stochastic models have also been proposed within different academic literature (Andrews et al, 2013;Zhang et al, 2014), but unlike statistical models, they have not been adopted widely within the railway industry. Monte Carlo simulation (MCS) was identified as an efficient method for such stochastic modelling (Quiroga et al, 2011), as it can be used to run hundreds of thousands of iterations before arriving at a track condition with the highest probability of occurrence for a given time. This paper adopts a stochastic track quality deterioration model using MCS suggested by Quiroga et al (2011) and assumes the track quality to be a linear function of cumulative tonnage or time and is given by Equation 1.…”

“…The most relevant superstructure track failures can be sorted into two main groups [26], i.e., i) track-geometryrelated faults (cross-level, alignment, longitudinal levelling, twist, and gauge) and ii) rail-surface-related faults (surface, corrugation, long and short waves). It is worthy to notice that the above classes of failures are strictly dependent.…”
