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...

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...

Accurate measurement of the railway track geometry is a task of fundamental importance to ensure the track quality in both the construction phase and the regular maintenance stage. Conventional track geometry measuring trolleys (TGMTs) in combination with classical geodetic surveying apparatus such as total stations alone cannot meet the requirements of measurement accuracy and surveying effici...

One of the characteristics of public transport is the need for transfers. During transfers, travellers are pedestrian wayfinders and have to find their way from the place of arrival to the place of departure of another means of transport. Wayfinding in public transport takes place in two types of spaces: network space and scene space. Network space includes the transport network. Scene space co...

The weak expansive soil subgrade of the railway in operation is prone to settlement a high-temperature climate, which results rapid deterioration geometric dimensions track, and affecting safety train operation. This paper uses Track Geometry Measurements (TGM) analyze characteristics track geometry parameters soil. Also establishes Settlement Prediction Model (SPM) identify time predict value ...
