  • Recently, fundamental innovation for the improvement of Korean railway industry is proceeding with the vertical separation into infrastructure and operation, and the privatization of railway operation. And also, with the advent of an era of high-speed railway, starting of Korea Train Express (KTX) will give a great change to circumstances of railway industry. It requires that a railway safety regulation policy and accident survey system cope effectively with this restructuring of railway system. Under these great changes, safety must have the first priority, and the function of management and supervision on railway safety will be ten to the governments responsibility; In this paper, according to changes of railway safety management system, foreign states railway accident system and direction of korea railroad accident survey system will be also introduced.

  • A Structure of a system is usually described as same as an architecture, but they are basically different. The architecture has a broader meaning than a system structure. In other words, an architecture can include many of system structures. So, to define the architecture, we need to consider how functions of a system are consisted and integrated. The architecture defined is applicable to railway safety management systems, and it can be made as a new model for railway safety systems, which is useful to systematize railway safety regulations. To establish the architecture as applicable to railway safety regulations, it is required to compare between regulation relations by analyzing roles before/after executing railway safety regulations. Therefore, in this research, we reviewed and classified different types of regulation conditions and safety requirements for railway systems and a variety of conditions before/after railway safety regulations changes are compared by defining system architectures subject to National railway safety.

  • Risk assessment of a railway system should be periodically conducted managing a large amount of accumulating accident/incident data and scenarios, which generally requires enormous time and efforts. Therefore, special information management system is essential for railway risk assessment, where data needed for decisions on managing the railway safety could be promptly supported. The objective of this study is to develop a railway accident analysis program for risk assessment. The program is application running on the web which links railway accident analysts throughout the railway industry to a central database. Data entered, together with associated code tables. is stored on MS-SQL database. The program uses the concepts of accident, safety events, causes, related factors(vehicle, person, infrastructure, tool/equipment), recommendations to bring together the various elements of railway accidents. The program will be useful in finding hazard conditions, accident scenarios, quantitatively assessing the risk, and providing pertinent risk measures, eventually serving to prevent railway accidents and reduce severities of railway accidents.

  • The creation of a single European rail transport market it is important to increase confidence between the actors on the market and between member states who shall ensure that railway safety is generally maintained and, where reasonably practicable, continuously improved. For this purpose the European railway safety directive introduces a mechanism to adopt a Common Safety Targets (CST) expressed in risk acceptance criteria for individuals and for society. This paper focuses on the apportionment of safety targets for European railway system. We develop a generic approach based on the Functional Hazard Analysis (FHA), to analyse the safety of railway systems for a unified European network and to comply with the CSTs required by the European railway Safety Directive. We suggest to combine the FHA technique with the functional railway architecture to allocate the safety targets to the railway functions.

  • IEC 62278, a standard for Railway applications of RAMS, was established in 2002. This IEC standard is based on CENELEC EN 50126 and covered overall railway fields. Activities that had to be performed from concept to decommissioning and disposal of railway system life-cycle, were contained in this standard. On the flow of internationalization, our Railway Authorities and railway support industry need to understand and apply this standard to railway fields. In this paper Railway RAMS in IEC 62278 is introduced.

  • Even though we usually analyze logistic market based on confined railway logistics, but this study would like to judge what is potential demand transferable to railway goods through accurate analysis of railway sharing rates by the analysis of origin and destination of each item in total freight transportation market. Accordingly, by analyzing each items transferable to railway, excluding items stuck to original market, this study wants to choose some major items which are expected to lasting demand and activate railway logistics plan by focusing on major items for marketing strategy.

  • A holistic approach is needed in railway network modernization. What matters is that each route is developed optimally throughout its life to meet business needs - whether the answer at a given point in time is a rail repair or an redevelopment scheme. Modernization of railway network will bring railway systems up-to-date, enabling them to deliver optimal performance. As the result, the railway network modernization for revitalise the railway is based on seeking out optimum conditions for financially efficient infrastructure management, developing infrastructure fully in line with market needs and last but not least, improving railway business.
