Risk management is an important part of system assurance and it is widely used in safety-related system. Railway signal system is one kind of safety-related system and its most important goal is to guarantee the safety of railway system. The method based on risk management can find and solve the security issues of railway signal system more effectively. This paper introduces the basic conceptio...

Railway traffic has increased over the last decade due to greater energy costs and the need to reduce emissions. Ensuring the dependability and capacity of railway infrastructure requires efficient and effective maintenance which, in turn, requires good understanding of various physical behaviours, e.g. deterioration and environmental effects. This paper studies the effect of cold climate on ra...

Passenger flow safety detection in high-speed railway transport hub is considered in this paper. For accurately detecting the passenger flow safety, an improved watershed algorithm and a recognition algorithm are respectively proposed in sensor-based detection process. Computational experiments on sensor data from a specific Chinese high-speed railway transport hub show that the proposed algori...

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 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...
