Given a railway network together with information on the population and their use of the railway infrastructure, we are considering the e ects of introducing new train stops in the existing railway network. One e ect concerns the accessibility of the railway infrastructure to the population, measured in how far people live from their nearest train stop. The second e ect we study is the change i...

Planning a railway infrastructure is an extensive process. Placement and interaction of all infrastructural elements including security components like signals and level crossings has to be considered. Verifying the railway infrastructure against legal guidelines is an important task within this planning process. The verification purpose is to ensure a safe operation on the infrastructure. Duri...

In an effort to protect the quality of the water system, interest in non-point source pollution is increasing. Recently, studies of non-point sources pollution are continuing in relation to various land-use areas, but such studies have not been fully conducted in railway facility sites. Using monitoring data of railway bridge area with concrete road-bed, the runoff characteristics, pollutant un...

With the development of economy and the progress of science, the proportion of electrified railway load in the power gird has been keeping on increasing, which impacts the short-term forecasting in load a lot, therefore, it is very important to analyze short-term load of electrified railway forecasting. This paper analyzes the power gird load-forecasting considering the influence of the electri...

(Received: November 21, 2013; Accepted: November 29, 2013) The objective of this paper is to control the railway tracks by using anti-collision techniques. The model of railway track controller is designed by using 8952 microcontroller to avoid railway accidents. When we go through the daily newspapers we come across many railway accidents occurring at unmanned railway crossings. This is mainly...

In order to support the market opening across Europe, the European Commission decided to define a common and harmonised approach for managing the railway safety. To take this forward, the EU Legislators have approved in April 2004 the railway safety directive 2004/49/EC. This directive allocates amongst others the task of defining a Common Safety Method (CSM) on risk evaluation and assessment t...

As one of the main aerodynamic noise sources of high-speed trains, the bogie is a complex structure containing many components and the flow around it is extremely dynamic with high-level turbulence. Flow around a simplified bogie at scale 1:10 is studied numerically using Computational Fluid Dynamics (CFD) for comparison with experimental measurements. The upstream inlet flow is represented as ...

The efficient use of infrastructures is a hard requirement for railway companies. Thus, the scheduling of trains should aim toward optimality, which is an NP-hard problem. The paper presents a friendly and flexible computer-based decision support system for railway timetabling. It implements an efficient method, based on meta-heuristic techniques, which provides railway timetables that satisfy ...

In this paper, we review the main concepts and methods to perform capacity analyses, and we present an automated tool that is able to perform several capacity analyses. Capacity is extremely dependent on infrastructure, traffic, and operating parameters. Therefore, an in-depth study of the main factors that influence railway capacity is performed on several Spanish railway infrastructures. The ...
