Cover Story: This paper analyzed the change in track gauge in the curves (transition, circular and entire) of ten Hungarian rail lines for ten years, including five lines with low traffic levels and the other five with high traffic levels. Statistical calculations were performed. The change in the track gauge parameter was analyzed based on the distribution functions by calculating the Vaszary-type shape number. A statistical test with the Kolmogorov–Smirnov test was executed and whether the measurement data of the railway lines followed a normal or lognormal distribution was analyzed. The skewness and kurtosis parameters were also examined. It was concluded that the type of the track system and the sleeper type influence the change in track gauges in curves. The exact deterioration ratios for all analyses are contained in this paper. View this paper
