Train performance analysis using heterogeneous statistical models

This study investigated the eect of harsh winter climate on the performance of high speed passenger trains in northern Sweden. Novel approaches based on heterogeneous statistical models were introduced to analyse the train performance in order to take the time-varying risks of train delays into consideration. Specically, stratied Cox model and heterogeneous Markov chain model were used for modelling primary delays and arrival delays, respectively. Our results showed that the weather variables including temperature, humidity, snow depth, and ice/snow precipitation have signicant impact on the train performance.Special issue, also published as printed edition:Emerging Hydro-Climatic Patterns, Teleconnections and Extreme Events in Changing World at Different Timescales / [ed] Ankit Agarwal, Naiming Yuan, Kevin K.W.
