  • The amended law of railway safety in Korea has recently come into effect in order to strengthen the railway safety management system. The new law, which took effect March 1, 2014, will implement stricter oversight of railway companies. As a result, a company that manufactures railroad system or components for domestic use must obtain an approval in accordance with the technical specifications of manufacturer approval. Although Korea had established the legal system in enforcing railway safety, the government wants the companies continue to develop the more improved safety systems until they gain competitive edge on the world class railway manufacturers. This paper presents an in-depth analysis of the technical specifications for manufacturer approval in International Railway Industry Standard (IRIS), which is the global standard. This paper also proposes measures and guidelines that would help Korean manufacturers those who want further develop their safety management systems, as a prerequisite for them to obtain the manufacturer approval.

  • A study on Technical Specifications of the current collection system in G7 Korean High Speed Train Project is performed in this paper. First, an appropriate level of contact wire tension for 350km/h commercial operation is proposed based on the foreign high speed train operation experiences and a relevant technical criterion, Second, two optimized design specifications of the pantograph for G7 Korean High Speed Train are proposed based on current collection quality. In order to perform design optimization, a formulation on the follow-up characteristics of a pantograph with 3 levels of masse-spring-damper is derived in this paper. Dynamic design parameters of the pantograph are adjusted to maximize follow-up capability at the dropper and span passing frequencies.

  • The railway industry is constrained by barriers within itself, which prevent it from competing effectively with other means of transportation, particularly road transportation. Therefore, many countries have adopted the policies that aim to remove barriers to providing international transport services by creating a common framework for railway industry. Recently, the European Union has produced the European Interoperability Directives, which aim to remove the technical problems involved in running trains between member states. In this respect, it is important to harmonize the technical requirements and specifications of Korea railway industry. This paper presents an action plan for the advancement of railway technical specifications in Korea. For this, the railway law and regulations of other countries are reviewed. Also the technical problems and operational barriers of railway industry are analyzed in Korea. This will help transportation agencies to resolve the technical problems of criteria in Korea railway industry.

  • Technical Specifications (TSs) for a nuclear power plant is an important licensing document which defines various operational requirements or conditions. Recently, many researchers have evaluated the risk impacts associated with the TS requirements, using probabilistic safety assessments becoming widely available. This paper presents insights gained km our review of recent risk-based analyses of TSs, focussing on surveillance requirements and AOT (allowed outage time) requirements.

  • Mo-Am arch bridge is only the long-span bridge (with 125m span) in the Kyong-Bu high-speed line in service, while other bridges are PSC box girder bridges and steel composite bridges with span lengths of $25\sim50m$. However, in foreign high-speed lines, special cable-supported bridges like cable-stayed bridges and extradosed bridges are being adopted in earnest with technical specifications. The cable supported bridge is recognized as one of the indices of technology in civil engineering field, and thus it is being adpoted with a sense of rivalry in countries with advanced technology in railway engineering. In this paper, to apply the top-level cable-supported bridge technology to the domestic high-speed line up to 400km/h by establishing the technical specifications on cable-supported bridges including span length, the requirements for securing the dynamic stability and running safety of high speed train are analyzed through case studies for domestic and foreign cases.
