Abstract

The aim of this paper is to find whether there are significant differences in the running performance of different train series when running along the same high-speed line under the same circumstances. Axlebox accelerations have proven to be a useful indicator to monitor train-track dynamic interaction, thus serving as the basis of track maintenance. Nevertheless, there are still some doubts around possible remarkable differences in the running behaviour of different high-speed train series. In order to delve into this issue, three different train series currently operating in the Spanish high-speed network were monitored, and both lateral and vertical axlebox acceleration were gathered. Data from each train series were compared using different statistical significance tests. The 66.7% of tests show a noticeable difference in the running performance among the three train series. Hence, this factor may become relevant in some situations such as choosing the type of train series for track maintenance condition monitoring, or when choosing the type of train for providing commercial service.
