The Railroad Safety Act was implemented in 2005 due to the increased concerns regarding railroad safety since the Daegu subway fire in 2003. In line with this, the Act became a standard to build the total railroad safety systems which has been overlooked compared to the quantitative growth of the railroad business. The minister of the ministry of Land, Transportation and Maritime Affairs lays down the Act for railroad Companies to conduct emergency programs in response to the emergency occurring on the railroad such as fire, explosion, derailment, etc. By enacting the Safety Act, the nation's construction of the contingency management system for railroad emergency increased", and it made the railroad company prepare the Emergency SOP by establishing 'The guideline on the Establishment of the railroad Emergency Plan' in order to support the efficiency of the Act. In line with this, I would like to analyze a matter of system development and the main function of the "railroad Emergency Training Program" for activation improvement of standardized operation procedure developed through the 'Total capitalize Safety Technology development'.

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.

Recently the assurance of railroad safety is very important issue in KOREA because there are lots of changes in the railroad industries. The Railway Safety Act was established in order to cope with these changes effectively and prevent the railroad transportation accidents. According to this law, Korea Transportation Safety Authority (KOTSA) has been entrusted with 'Integrated Railroad Safety Audit (IRSA)' and has implemented the safety audit to the railroad operation agencies such as Korea Railroad (KORAIL) and the railroad facility management organization such as the Korea Rail Network Authority (KR Network). The target of IRSA is to establish the effective rail safety management system and to raise the safety level of the railroad operation and facility agencies by checking synthetically their performance of safety duties with sincerity according to the Railway Safety Act. The purpose of this paper is to improve the efficiency of IRSA by the comparative research between IRSA and other similar safety audit system. To study the efficiency of IRSA, we investigated the rail safety audit systems of EU system specially France, England where the big changes have happened for the rail operation concepts and Japan where government entity control the railroad safety. The international standards of Occupational Health & Safety Assessment Series (OHSAS 18001), Quality Management System (ISO 9001) and Guidelines for Quality and/or Environmental Management Systems Auditing (ISO 19011) are investigated.

In the Korea, railroad accidents result in about 5.4 railroad run-off crashes every year and account for approximately 93 percent of all railroad accident frequency. Despite the number, quantification of the possible countermeasure has been limited and also railroad safety control after private management for railroad has not been established. Therefore, this study provides some initial insight into the important safety problem by introducing some example, including some detailed safety regulations in both British and U.S. to develop appropriate railroad safety management system.

The advent of private railroad corporations presented many problems on administration's effectiveness. These brought an effect on safety management too. Most public railroad corporations maintain their rolling stocks and facilities by their own workers. On the other hand, private railroad corporations depend on outsourcing to cut down the cost of maintenance. But they have similar safety management systems. Therefore we investigated the gap between the two types of corporations, focusing on workers' safety attitude and proposed solutions to improve safety management systems in private railroad corporations.

Derailment due to wheel failure would cause a tremendous social and economical cost in service operation. It is necessary to evaluate quantitatively the safety with respect to high-speed train. Although the safety of railway wheel has been ensured by an regular inspection, all critical defects cannot be detected in inspection cycles and the wheel has been replaced because a defect quickly become critical for safety. Therefore, it is important to calculate quantitatively the fracture limit and remnant life of damaged railway wheel in wheel-rail system. In present paper, the critical crack size of wheel for high-speed train is simulated based on fracture scenario and the safety of wheel is evaluated.

In January, 2005, the "Railroad Safety Act" was presented, preparing the systematic equipment that allows several railroad operators to consider the railroad safety issue, and each of the railroad operative institutions accepted such situation that the construction of the emergent system of coping, resulting in the construction of the emergent system of coping with the railroad fire accident through the relevant study to improve the railroad security efficiency against fire. This study tried to present the on developing the emergent educational program for coping with the KTX fire accident, which is distributed to the spot, to the railroad emergency staff for improving the railroad security efficiency against fire through the education of systematic and efficient emergent countermeasure procedures against fire accidents the fire accident in KTX.

A great deal of development has been made in the field of railroad control in Korea. Like the recent High speed railroad (KTX) and the intercity light rail train (LRT) are being vigorously promoted. Therefore, in concert with the new railroad development projects, improved train control technics are being applied. Along with the focus on these newly developed advanced technologies the need for a reliable safety system for the safety of the passengers and railroad control personnel alike is being intensified. New safety facilities are continuously being developed in order to safely introduce and develop these new technologies. There is an urgent need for research and development of safety facilities for the implementation of the presently developed facilities as well as for the presently being used. Therefore, this research will study the safe operation of Korean railroad and the implementation situation of the class, functionality, ensured safety range etc. of the safety facilities for users and operators. In studying the material of the kinds of implemented safety facilities and technologies being used abroad we have researched into the most suitable direction of development of safety facilities for the Korean railroad environment.

In Korea, the number of railroad accidents is decreasing, but the scale of railroad accidents tend to be growing large. On considering the opening of the high speed railway in 2004, the problem of railroad safety is very important. The purpose of this study is to make plans for improving railroad safety of Korea. To make this plan, we generally analyzed the future railway traffic, and reviewed annual statistics of railroad accidents trend and case studies of foreign railway accidents.

The railroad facilities are intended for long-term operation as the initial acquisition costs necessary for infrastructure construction are high. Therefore, regular maintenance of railroad facilities is essential, and furthermore, system reliability through systematic performance evaluation is required. In this study, the signal control system of railroad electrical equipment was selected as the subject of research and the performance evaluation target facility selection study was conducted using AHP. The results of the study can contribute to the reliability of the signal control system as well as to the reliability of the railroad system, which is a higher system.
