Since 2012, European high speed railway networks are meant to have gone to market. Hence, several high speed trains, such as ICE, TGV, ETR 500, Sapsan..., are likely to run on the same tracks, whereas they have been originally designed for specific and different railway networks. Due to different mechanical properties and structures, the dynamic behaviors, the agressiveness of the vehicle on th...

Zaitsev1 1ITEP, Institute for Theoretical and Experimental Physics, Russia; 2GSI, Darmstadt, Germany; 3KIP, University of Heidelberg, Germany The cellular automaton (CA) based track finder of the CBM experiment [1, 2] is a flexible algorithm operating on space-points which makes it maximally independent of the actual geometry ...

the main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. therefore, railway track desig...

In a context of increasing interoperability, several high speed trains, such as ICE, TGV, ETR 500, are likely to run on the same tracks, whereas they have been originally designed for specific and different railway networks. Due to different mechanical properties and structures, the dynamic behaviors, the aggressiveness of the vehicle on the track and the probabilities of exceeding security and...

In this project, we explore a data-­‐driven approach for monitoring rail infrastructure from the dynamic response of a train in revenue-­‐service. Presently, rail inspection is performed either visually or with dedicated track geometry cars. We examine a more economical approach where ...
