چکیده
Abstract: To evaluate train-running safety during seismicity on an entire railway line quantitatively, we should use risk analysis method. A lot of studies for seismic risk management were widely performed in various kinds of research fields. However, the study for fragility curve of train-running safety has not been conducted and its basic characteristics have not been obtained. Through this study, we clarified the PGA and PGV fragility curves on entire railway line based on a numerical analysis, as well as influence of train-running direction and phase difference of earthquake motions. We also investigated verification for vehicle guide device, which minimized damage when railway vehicle was derailed by a large-scale earthquake.

A Study of the Wear Behavior of a Rail Material
The rail track is one of the most important elements of a railway system. During the passage of trains, the rails are subjected to contact load that comes from the wheels of the train. The railway track often fails in service due to wear caused by contact fatigue and other wear damage mechanisms that could also limit the life span of the railway infrastructure and railway vehicle. The aim of t...
متن کاملEffect of Rail Corrugation on the Amount of Train Induced Vibrations near a Historical Building
The evaluation and control of the trains induced vibrations needs even more attention in the case of underground tracks which passes near to monuments and historical sites. The rail corrugations which occur due to the wheels’ impulse loads during the operation period of underground railway tracks, usually amplify the ground borne noise and vibration. In the current study, the mentioned phenomen...

This paper develops a methodology which allows the correlation between the cost which is required for the application of preventive and mitigation measures dealing with accidents which occur within a railway system and the improvement of the level of safety as a result from their implementation. The safety level is expressed either quantitatively, by the decrease of “fatality risk” indicator...

Risk assessment is becoming increasingly important for railway signal system in order to safeguard their passengers and employees while improving safety and reducing maintenance costs. However, the application of risk assessment methods in railway signal system may not give satisfactory results because the risk data are incomplete or there is a high level of uncertainty involved in the risk dat...
متن کاملSolving railway line planning problems using a decomposition algorithm
The passenger line planning is a process of strategic long-term decision-making problem in the field of railway passenger planning. A line is a route between starting point and destination with certain stops, which has a certain frequency of train schedule. A new solution based on decomposition algorithm has been proposed in this paper, which is defined in a master problem and two sub problems....
