Detailed yet computationally efficient simulation models are needed to support the design and operation of modern rail infrastructure systems. LIBROS-II is a model component library for microscopic rail operations simulation. Basic rail elements are modeled as atomic DEVS models which are further aggregated into more elaborate rail component models. The latter can in turn be used modularly for ...

The demand for safe, fast, and reliable rail services continues to be the reason for concern in all the countries across the globe. Lack of operational efficiency and reliability, safety and security issues, and aging railway systems and practices are haunting various countries to bring about a change in their existing rail infrastructure. The global rail industry struggles to meet the increasi...

This paper explores the development of rail systems in Ireland and Australia. The paper highlights the different trajectories of both systems and charts the experiences and influences of Empire and Commonwealth on both. In Australia the rail system was developed as a way to promote nation building and overcome isolation while in Ireland both prior to and after partition the system enabled acces...

in this paper, the main factors in the analysis of the railway concrete sleepers areinvestigated and new recommendations are made in order to improve the accuracy of the currentpractices in analysis of the railway track system. first, a comprehensive literature survey isconducted, then, fem models for a railway track system are developed and used to discuss andevaluate the assumptions commonly ...

This paper advances the field of network interdiction analysis by introducing an application to the urban rail transit network, deploying protective resources against intentional attacks. The resource allocation problem for urban rail transit systems is considered as a game between two players, the attacker interdicting certain rail stations to generate greatest disruption impact and the system...

This paper describes a system for automated rail scheduling currently being developed at Dutch Rail (NS). This system will be used initially to base infrastructure decisions upon. Rail infrastructure poses constraints upon the rail schedules that can be made within it, because of the large extent in which trains share it. Good infrastructure is the one that allows good schedules. The Petri net ...

In this work, a Euclidean distance calculator is presented. The circuit comprises of simple computing blocks, their basic element being the floating gate MOSFET (FGMOS), exploiting the merits of this device in designing circuits with low-voltage and rail-to-rail operation. Therefore the overall circuit has the characteristics of modularity, low-voltage and rail-to-rail operation under a single ...

In comparison with the other transportation modes, rail rapid transit already enjoys a higher degree of safety as it is designed with the exclusive right of way and the automatic train control and monitoring systems. Nevertheless, rail rapid transit systems are not free from serious accidents, which often led to human injuries and facility damages. The planning of accident prevention and emerge...

The purpose of this study is to provide a model with a dynamic system method to investigate the factors affecting the technological capabilities enhancement in the high-tech industries of high-speed train of the rail transportation system. For this purpose, after reviewing the literature and conducting several meetings with experts in the rail transportation industry, a conceptual and qualitati...
