The Alp Transit Gotthard is an ambitious railway construction project, which will incorporate the world's longest railway tunnel of 57 km travelling through the Swiss Alps and under the St. Gotthard massif. Future passenger trains will journey at speeds of up to 250 km/h, adding further to the highly successful European high-speed network and bringing a huge reduction in travelling time. The co...

In this article, we address a variant of the rolling stock (RS) problem in dense railway systems within a metropolitan context. It consists in determining every train composition and scheduling empty trains to efficiently fit the demand. By empty trains we refer to scheduled trips where trains travel along the system without carrying passengers. A heuristic is presented to generate eligible slo...

Petri Net being one of the most useful graphical tools for modelling complex asynchronous systems, we have used Petri Net to model multi-track railway level crossing system. The roadway has been augmented with four half-size barriers. For better control, a three stage control mechanism has been introduced to ensure that no road-vehicle is trapped on the level crossing. Timed Petri Net is used t...

High-speed railway is playing an important role in mass transportation, due to its lower energy consumption, less environmental pollution, larger capacity and higher safety features. The development of high-speed railway makes people's life more and more convenient. Meanwhile, providing high quality of service broadband communications for fast-moving users still remains unsolved, despite the fa...

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 ...

Özet When compared with the other transportation systems, railway systems are economical, safer and more environment friendly. Despite all these features, investments on railways in Turkey remained quite restricted in comparison to other European countries. The initial construction costs of railways are high and developing its signaling system also requires a lot of attention. Signaling system ...

As railway signalling systems hardware improved from mechanical switches and electrical relays to electronic tubes and semiconductors, the software improved from direct control and event-driven approach to object and agent-oriented programming. This paper aims at the use of agent-oriented programming for railway applications. In order to do that some agent basic concepts such as organizations (...

s light rail transit (LRT) systems mature and expand, outlying passengers are faced with increasingly longer trip times to reach the urban core. Providing service to these customers by conventional means can be disproportionately expensive for the transit carrier in terms of operating and capital expense. Innovative operational practices to expedite train movements, however, are often confounde...

At the beginning of 1820s. Marc Seguin and his brothers started negotiations with French government for the construction of a railway line from the Saint-Etienne coal field to the Rhone valley and the city of Lyon. This railway is the first French railway using locomotives. Because there are few papers and publications on the history of this important railway, the writers have studied about the...

OVERVIEW: The primary role of a signaling system is to ensure the safe and stable running of trains. There is also a great need, however, for improving the efficiency of railway operations and reducing the maintenance cost through the modernization of signaling systems. One approach to meeting these needs is a highly safe and highly functional signaling system using general-purpose computers. H...
