  • The railway has been developed largely by the characteristic factors of the railway through change of the society and culture. The railway trends has been changing from instinctive methods to settle the mass transport of the early days, to sensitive methods to pursue the railway culture centering around human being. As dividing by period according to the changes of railway trends into the external nation, there are to analyze the development history of the railway design. Accordingly each nation (United Kingdom, Germany, France, Japan) and the style's change, to confirm the changes into the design applied in society and culture needs, and to analyze by a year in changes of the environment and the railway history from the 1800's to 2005, so there contribute in the development of railway design to present the paradigm of the future railway by analyzing the trend according to the changes of railway design and the life environment in this paper.

  • Studied was a strategy of technology development for railway system in terms of railway network. First, The successful launch of the Korean HST system has not only decreased logistics burden but also significantly transformed the Korean trunk-line railway network, revolutionizing the logistics and technology sectors and reinvigorating the Korean railway industry in one century. Korean railway industry sector is now investing to develop many different types of railway system(G7, Post G7, tilting train...) so that these kinds of various railway system development should be integrated with the National Inter-modal Transportation Network Plan. To secure sufficient capacity that is required by the National Railroad Plan, the railway industry needs to establish mid- and long-term train purchase and operation strategies in compliance with railway construction and operation policies. During a railway construction planning, train operators, based on their train operation strategies, should come up with measures to closely cooperate with project operators from the planning stage through to the opening of a railway system. To be more precise, train operators should establish long-term train procurement plans reflecting both long-term national railroad network plans and plans for each railway line in order to suggest appropriate roles and schedules for each line. Also, based on the long-term railway plan, directions should be decided concerning the research and development of trains in advance.

  • The purpose of research will establish the foundation to enhance the skills of Railway Color Design in the future by accurately analysing the Railway Color characteristics. The emotion and demnds of times influences trend of Railway Color Design, the contents of this research also reflects trend in society and culture. The research contains the history of Railway Design and advance research of Railway Color trend especially influenced by society and culture in the from the 1960's to the year 2005. The study is based on the concept of Railway Color Design. it analyzed the related current of society, culture and Railway Color. Collected Railway Color samples(Railway 46 images) were studied by using visual sensation. The Munsell Color System was used as references. This research analyzed railway introduced as railway models by top 4 nation (United Kingdom, Germany, France, Japan) and Korea in the past years(1960-2005) for their Railway Color Design trend by Munsell Color System. Although the Railway industry has rapidly risen according to life style in society and culture, there has been a lack of organized data for Railway Color Planing. this research on the basis will offer the significant information for Railway Color Design.

  • A railway station is a place where the railway operator concretize his marketing policy to meet the internal and external changes of a railway. Hence the analysis on the railway stations could give some useful information on the conditions which influence the shape of railway station. The purpose of this study is to analyze the development of Japanese railway stations. This study shows that the influencing factors on the shape of Japanese railway stations are as follows: invitation of investment from outside the japanese railway, necessity to define measures against the cut off the urban fabric by the railway facilities, profitability of the railway operator by the creation of subsidiary business, integration of administrative or public function into the station building. And the future of Japanese railway stations is now preparing by the policies on the accessibility and commodity of users and by the research projects on the environmental quality, user satisfaction.

  • The railway system requires safety and reliability of service of all railway vehicles. Suitable technical systems and working methods adapted to it, which meet the requirements on safety and good order of traffic, should be maintained. For detection of defects, non-destructive testing methods-which should be quick, reliable and cost-effective - are most often used. Since failure in railway wheelset can cause a disaster, regular inspection of defects in wheels and axles are mandatory. Ultrasonic testing, acoustic emission and eddy current testing method and so on regularly check railway wheelset in service. However, it is difficult to detect a crack initiation clearly with ultrasonic testing due to noise echoes. It is necessary to develop a non-destructive technique that is superior to conventional NDT techniques in order to ensure the safety of railway wheelset. In the present paper, the new NDT technique is applied to the detection of surface defects for railway wheelset. To detect the defects for railway wheelset, the sensor for defect detection is optimized and the tests are carried out with respect to surface and internal defects each other. The results show that the surface crack depth of 1.5 mm in press fitted axle and internal crack in wheel could be detected by using the new method. The ICFPD method is useful to detect the defect that initiated in railway wheelset.

  • Recently, the Korean government is considering a policy of adopting competition in railway transportation, such as the establishment of a subsidiary company to Korail as a company to operate a part of the KTX line, the separation of deficit-running lines of local railways and the opening of railway transportation to private operators. The termination of local railway service, which is a major provider of public transportation, will not only deprive the public of a means of transportation but also lead to a decline in the quality of public transit in general. The termination of local railway service is being decisively affected by the national railway policy. The purpose of this thesis is to clarify local railway policy in Japan by studying the development and philosophy of the local railway policy of the Japanese National Railway (JNR).

  • The interests about railway safety have been highly increased. Early railway safety was widely studied in Europe and Japan, and safety standards were established in 1990s. EN 50126 of CENELEC, Railway applications - Specification and demonstration of RAMS, became IEC 62278 in 2002. This standard provides Railway Authorities and railway support industry with a process which will enable the implementation of a consistent approach to the management of RAMS. IEC 62278 will be often referred to in the field of railway system. This paper examined the application of railway RAMS on basis of IEC 62278.

  • In this paper, we reviewed the evaluation methodologies of railway project considering the benefit incidence. Generally railway projects are much more reduced tile energy consumption, traffic accident and environmental pollution than road projects. But conventional B/C analysis of railway project does not measured including those benefits. Also there is a few attention to an incidence of benefits producing from railway construction. So we developed the evaluation method of railway project contained the railway oriented benefits and also considered of the benefit incidence producing from railway construction.
