Traction power supply equipments are the core part of the high-speed railway, so the maintenance of the power supply system is crucial for the security of the railway. Based on the research on the durable years of the traction power supply equipments, this paper puts forward the model of testing the traction power supply equipments of the reliable high speed railway. Some practical researches h...

In the context of making timetables for railway companies the following railway carriage routing problem occurs. Given a timetable containing rail links with departure and destination times/stations and the composition of the trains, nd a routing of railway carriages such that always the needed carriages are available if a train departs. We will present a local search approach for this routing ...

the vibrations produced by trains include two parts which are deterministic and random vibrations. due to variation of dynamic loads and patterns of load-time, the random vibration of moving train is one of the most important issues in the field of railway engineering. one of the important sources in producing the train vibrations is rail roughness and irregularities. in this paper, responses o...

The paper outlines the main constituents of occupational risk in railway workers, which are based on the sanitary and biomedical criteria of injury safety. Sociomedical aspects of the incidence of railway occupational diseases and injuries are discussed. A list of major occupational factors and causes that determine a high occupational risk in railway workers is given.

BACKGROUND The majority of fatalities on the European Union (EU) railways are suicides, representing about 60% of all railway fatalities. The aim of this study was to compare time patterns of suicidal behaviour on railway tracks in Germany between two observation periods (1995-1998 and 2005-2008) in order to investigate their stability and value in railway suicide prevention. METHODS Cases we...

Passenger rail transport market share has been drastically reduced in the last fifty years. The reforms were aimed at opening the market of railway services and development of competition in the railway sector in order to obtain the benefits of “market forces” and reduction of interventions in the railway sector. Determination of the level of reform often causes confusion and conflicting opinio...

t: -The railway tourism has become a trend due to cultural heritage preservation. There have been voices calling for re-opening of the Old Mountain Line Railway. The service quality controlled by the management will have a great influence on tourists’ intention to use the railway again. Therefore, the service quality after the railway re-opening is the key issue to be considered when it comes t...

Safety should be the primary concern when building a railway network. The safety of a railway network typically depends upon the use of track-side signals in regulating the safe passage of trains. Establishing the correctness of the systems that control the track-side signals therefore plays a crucial role in ensuring the safety of the railway network. The aim of the assignment is to develop a ...

This study aims to investigate the effects of the centralized allocation and optimization of Taiwan’s railway resources (personnel and equipment) on the overall operational efficiency of its railway industry, based on the concept of two-phase centralized allocation and reallocation of resources. A Taiwan railway data analysis conducted in 2011 showed that the high overall output due to the effi...

The project named “the rescue system and key technology of high-speed railway in perilous mountains” primarily focuses on current railway constructions and operations in China. To state the relationship between risk events and risk factors, we classified the risk sources of operating tunnels of high-speed railway in perilous and mountainous area and established a hierarchical assessment system ...
