In 2004, railway safety law was established since intimidatory factors have increased for railway industry, such as high speed rail, urban transit extension, induction of new transportations. The projects for safety system establishment and guidelines are performed including the safety guidelines for station and platform. Therefore, in this study the safety rules are examined through investigation for stations

Currently, the Korean railway standards (KRS), managed by Korea National Railroad, have been managed by the Korean Ministry of Construction and Transportation. According to Korean railway safety law, which were established for the guarantee of railway safety, the management of KRS including enactment and revision of technical standards for railway vehicle and components, was committed to Korea Railroad Research Institute (KRRI). In this paper, the detailed master plan for the management of KRS will be introduced for the effective management of KRS, and KRS management direction for the future will be suggested.

As the Korea Railroad (KR) was privatized at the beginning of 2005, the Korean Railway Standards (KRS), which was managed previously by KR, have been managed by the Korean Ministry of Construction and Transportation. According to Railway Safety Law and ordinances, which are for the guarantee of safety in railway applications, the management of KRS including enactment and revision of technical standards for railway vehicle and components, was committed to Korea Railroad Research Institute. In this investigation, the detailed management plan and contents are introduced for the effective management of KRS.

The purpose of this study is to develop automated structural design and analysis aided-program of aluminum extrusion carbody structures for railway vehicle. This developed program is possible to perform simultaneously structural design and design verification of aluminum extrusion profiles independent of expertise and experience of design engineers. Design engineers was able to design it using database of existing aluminum extrusion profiles or user-defined function. The design verification was programmed to evaluate its structural integrity according to Korean Railway Safety Law or Urban Transit Safety Law. Also, this program could automatically generate an executable file of various commercial finite element program and CAD files such as stp and iges by GUI environment applications using MFC(Microsoft Foundation Classes). In conclusion, it is expected to contribute to reduce product development time and improve product quality of aluminum extrusion profile and structures in railway industry.

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 government of South Korea has made great efforts in the area of railway safety management by means of a railway safety law and an integrated railway safety plan established in 2004 after the Daegu subway fire accident. However, after certain railway incidents, a reactive railway safety management system has been implemented that has led to fatal accidents caused by the collision, derailment, and fire every year. Hence, this study is intended to propose a framework that integrates data from distributed detection devices into a real-time railway safety monitoring and control system for proactive safety management. Furthermore, we will provide a future development direction for safety performance monitoring indicators to determine whether the railway safety monitoring and control system works effectively. The proposed framework is expected to be a cornerstone for the real-time railway safety monitoring and control system to be implemented in the future.

The purpose of Overall Railroad Safety Audit(ORSA) is to prevent railroad accidents, and, every two years, to inspect and evaluate whether or not railroad operators faithfully adhere to railroad safety guidelines in accordance with the Railroad Safety Law. However despite of the many contributions of ORSA, due to lots of railroad accidents such as train failures and derailment caused track irregularity this year, it has been recently considered that ORSA will be renewed into Safety Certificates System as a complement. In order to guarantee railroad safety, new Safety Certificates must included appropriate safety standards considering current our country's railroad conditions. Therefore, in this study we're going to compare safety components of foreign audit system with those of Airlines field, based on ORSA's contents for years, to review Safety Management System and Safety Culture, as a result, we'd like to suggest to updated Railway Safety Standards.

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.

Hyundai Rotem Company has designed and manufactured the next generation high speed EMU bodyshell (M3-car). Korean Railway Safety Law specifies the loads vehicle bodies shall be capable of withstanding, identifies what material data shall be used and presents the principles to be used for design verification by analysis. Therefore, in order to fulfill the structural requirements, Hyundai Rotem Company has carried out Finite Element Analysis (FEA) and static load test to verify whether the carbody structure has enough strength to withstand the loads specified by Korean Railway Safety Law. This research contains the results obtained by the FE analysis and static load test. The FE analysis is carried out using NX I-DEAS 6.1 and specially designed test jigs and equipment are used for the load tests.

The importance of railway safety has become increasingly significant domestically as well as internationally, as a series of high speed railway accidents and other major accidents have occurred recently. Especially for the domestic railway, the Korean Railway Safety Law has been revised recently, mandates all the domestic railway operation authorities to render the performance of RAMS and RCM. This study inspects and analyzes the current status of the sensing technology of the electric detection system to tell the status of railway facilities in the highway railway in a real time through a sensor. It also performs the reliability analysis of the electric detection system that is being progressed as a study assignment and suggests the system construction for the higher reliability.
