Restructuring of European railway companies has resulted in creating new subjects within railway systems infrastructure managers (IM) on the one hand and railway operators (RO) on the other. In this paper we examine the efficiency and rank different business strategies of railway infrastructure managers using the combined AHP/DEA method. Different strategies include different number of paths al...
The aim of this paper is to present the results coming from an experimental campaign aimed at definition vibrations acting on a powered and trailer bogie railway vehicle for mass rapid transit during commercial service. results, multiple sensors placed in specific points two wheelsets, can give significative overview dynamic behaviour components, highlighting, when present, notable differences....
Abstract Railway wheels are commonly made from medium carbon steels (~0.55 wt.% C), heat treated to a near pearlitic microstructure with 5–10% pro-eutectoid ferrite. During the operation of freight trains, where block brakes used, high thermal loads occur together contact stresses, which combined can affect mechanical properties material. In this study, effects annealing on local and in railway...

Abstract Tread wear and rolling contact fatigue (RCF) damage propagated on railway wheels are the two extremely important focal points as they can tremendously deteriorate wheel/rail interactions hunting stability destroy wheel surface materials, subsequently, cut down lifetime of wheels. The on-board anti-slip controllers essence aiming to hold back striking slipping powered wheelsets under lo...
