After 1860’s the railway systems has started to be used in urban transportation in the world. However, especially after the 1950’s, automobile usage has been increased quickly. Thus the dense of transportation has started to move from railway systems to the ones with rubber tire vehicles in Istanbul. Traffic density in urban transportation has started to be experienced since 1950 with the incre...

current practices in railway track analysis and design are reviewed and discussed in this paper. the mechanical behavior of railway track structure comprising of various components has not been fully understood due to the railway track structural complexity. although there have been some improvements in the accuracy of current track design methods in recent decades, there are still considerable...

INTRODUCTION TRANSPORTATION of people is increasing as our society grows and the demand for railway services that can provide high-speed and high-capacity transportation is becoming greater. The number of train rides taken in Japan in 2006 was 22,243 million, more than anywhere else in the world by some margin, making Japan one of the world’s leading railway nations. A major feature of railway ...

The most important issue in railway systems is to provide safe transportation. Since no error can be tolerated in railway systems it is an obligation to use reliable signalization and interlocking systems which have to decide what to do in unexpected situations like switch disruptions or signal light defects. By the rapid development in railway systems more formal methods are needed for modelin...

Active steering system of railway vehicles has proven its ability to bridge the gap between stability and curve friendliness. Generally scaled railway vehicles were developed to reproduce the fundamental dynamic behavior of the full size railway vehicle in laboratory conditions. This paper describes the design of the braking/traction control systems as a part of a 1/5 scaled railway vehicle for...

Mobile Laser Scanning (MLS) systems are widely applied for spatial data collection and support applications in many aspects. In recent years, MLS technology had been introduced to railway applications and greatly enhanced the spatial detail and efficiency when compared to traditional approaches. However, the advance of MLS technology is not completely applied to railway environment. Typical MLS...

This paper describes a railway system simulation to be used by train railway system operators. We have developed a learning tool for education, but, besides, different railway system models can be analyzed. Wedonot need to build the physical railway model, but may experiment with the planned system on the computer. The modeled system can be built easily and effectively and its behaviour may be ...

this article is concerned with the static analysis of structural cables used in railway overheads. structural analysis computer program named ansys is used for analysis. two effects are considered in the analysis. first one is the bending behavior effect of cables. beam188 in addition to link10 and link180 is used to see the difference in case of additional bending effect. besides, link10 and l...
