  • 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.

  • The communication protocol for interface among railway signalling systems is designed and established as national standard in Korean from a few years ago. So the communication link for information transmission among railway signalling system can be a good example of application of this standard. Communication protocol which is standardized among Korean railway signalling is considered to apply information transmission. And we confirmed there is no the states of deadlock of livelock in std. protocol which is applied formal verification which is one of the analytic method for inspection of safety characteristics in the design course of protocol. But the safety of protocol has to necessarily accomplish this normal analysis approach about satisfying requirement matters with such this analytic approach. In this paper we analyzed the safety characteristics of standard protocol for Korean Railway signalling through the requirement matters for safety transmission of railway transmission system which is required in international standard. So through this study we confirm whether it satisfies safety requirement matters of the level which require in international standard and tried to confirm whether standard protocol has enough safety character in the real railway field.

  • A standard framework of CFD(Computational Fluid dynamics) analysis for railway system has been developed to evaluate the overall aerodynamic performance of railway system and has been adopted to numerical simulation of the pressure field around KTX train. The framework is composed of standard aerodynamic model and standard aerodynamic performance to customize the general CFD solution process reflecting the characteristics of railway system such as various operation mode and performance factors. The results show that the standard framework of CFD analysis for railway system can provide objectivity and consistency to the CFD analysis for railway system and the pressure field around KTX train has been successively solved.

  • Safety is important factor in railway system. Now most of the electric and electronic system which is applied in railway system is the embedded system which software is used. The constitution rate of software which is involved in railway system is gradually increasing. Most of the software which is used in railway system is implemented by the software developer. Thus the implemented code has different features according to the developer and this may cause the bad effect on the software's maintenance. International standard IEC 62279 requires an adoption the coding standard to developing the railway software. And it is plan to recommend complying with the coding standard in safety criteria for railway software which is noticed as the regulation of the Korean railway safety law. In this paper, we review the requirement of coding standards which is present in the software criteria for railway software and international standard. Also it investigates the coding standard which is in other safety related industry and presents the effective way to apply the software coding standard to domestic railway industry.

  • The coldproofness should be studied in order to operate the freight car by connecting the South and North Korea Railway. Actually, there is no standard for coldproofness in South Korea Railway, The standard for coldproofness of the Russian Railway, the Chiness Railway and the North Korea Railway was studied. From the analysis of these standards, the standard of coldproofness was proposed for the freight vehicle connecting the South and North Korean Railway.

  • According to Korean railway safety law and its ordinances, the Korean railway standard(KRS)s to recommend railway operators and manufacturers the regulations for safety and inter-operability of railway system were enacted in the early 2006. In order to reflect rapidly advancing railway technologies and correspond to the international railway standard led by Europe and Japan, KRSs should be confirmed and revised continuously. This paper deals with recent trends in enacting international standards by IEC and the Europe and Japan's activities for this, and presents advancement directions for KRS.

  • Recently in Korea, noise is one of the most important social issues because the living standard becomes more higher. Railway noise is also annoying one in our society, although railway has very positive role in our country. The major measures for mitigation of railway noise in Korea are rail welding and installation of noise barrier on the noisy area. But these measures have its own limit for the calm and comfortable living environment. In Europe the railway noise problem has been treated more systematically and aggressively, there has been emission noise standard for Trans-European rail network. In this paper, the trend of noise standard for railway vehicles will be reported and the check point for our country will be discussed.

  • Railway bridge, contact of vehicle needs to design considering the running safety about the running train load of the railway bridge, ride comfort and dynamic safety. Also, upper structure of the railway bridge has to satisfy design standard about moving load(train). So, the railway bridge has to satisfy the requirement for vertical acceleration of the bridge deck, vertical displacement of the bridge and face distortion, which is suggested railway design standard in Korea(2011.5.). In this study, it was investigated and evaluated to the running safety about the running train load of the railway bridge, ride comfort and dynamic safety with railway design standard for steel composite(Steel Box Girder) railway bridge considering KTX, freight train and standard train load.

  • According to railway safety regulations for securing the railway vehicle's quality and performance, it can be partly exempted that the performance tests and production inspections on the railway vehicles which are produced and assembled for the purpose of test and research. The reasons of this exemption are for ensuring maximum autonomy and for saving time considered the development period of railway vehicle. However, it was continuously demanded the necessity of supplementation on the confirmation about railway vehicle's quality & performance. Therefore, we added "The monitoring step" which is for securing the quality and performance in high speed railway vehicle's subsystem & compartment to supplement those tests & inspections in development. In this paper, based on a standard ABS(Activity Breakdown Structure) of railway vehicle and a WBS(Work Breakdown Structure) of the railway vehicle system, we investigate the necessity of monitoring in the High speed railway vehicle development. And by comparing and analyzing the essential requirements of international standard, IRIS(International Railway Industry Standard) & TSI(Technical Specification for Interoperability), we try to examine a standard monitoring procedure.
