A railway is a complex system integrated with a lot of technical elements such as rolling stock, power, signal control, communications, tracks, stations, operation control systems, and so on. As a mass transportation system, a railway could contain potential risks that may result in a high death rate and property losses. Accordingly, Railroad Safety Technology R&D Corps. is adopting the plan of the construction of Railway Safety Test Facilities as a part of the Railway Total Safety Project to enhance the railway safety, and carrying out researches on effective project management methods with Systems Engineering techniques. To support that, we propose the more effectual management method of constructing the Railway Safety Test Facilities applying the model-based systems engineering tool to the research.

Railway safety aims to ensure that railways take appropriate action to limit the risk of injury to persons or damage to property, to acceptable levels. Accreditation system specifies railway safety requirements to be included in a railway safety management system by any organization seeking to demonstrate the ability to control the processes that determine the acceptability of railway safety activities. The objective of this research is to investigate the international accreditation system for railway safety management. The yield information is quite valuable to operate collaborative processes with all interfacing transport operators and undertakings to facilitate risk control across the railway system.

A railway is a complex system integrated with a lot of technical elements such as trains, track facilities, human factors, operation & control and maintenance. As a mass transportation system, a railway could contain potential risks that may result in a high death rate and property losses. Accordingly, Railroad Safety Technology R&D Corps. is adopting the plan of the construction of Railway Safety Test Facilities as a part of the Railway Total Safety Project to enhance the railway safety, and carrying out researches on effective project management methods with Systems Engineering techniques. Recently, various systems engineering tools such as CORE or Cradle are applied to manage the system requirements and the project management process in the part of the aerospace engineering and automobile engineering so on. The railway industry also makes an effort to develop an efficient management skills using systems engineering tools as the railway system is multi-disciplinary. Therefore, we propose the more effectual management method of constructing the Railway Safety Test Facilities applying the systems engineering tool to the research.

As technologies are developed and systems are complicated, hazards embedded in the system are also increasing. proving safety and managing the safetyis more scientific and organizational domain so that safety management system is pursuing to be activeformation detecting the factors of hazard and managing them beyond passiveway. In the future, in order to establish and manage national safety management system, it is important to have effective system and manage it and also more important that all the people related to target system has to change their recognition and to playroles in it. Many railway safety measures reduce railway fatalities into half for last 10 years. But more improvement in railway safety is required to meet the social need after railway fire accident in Daegue. After the Daegue subway train fire accident, the Korean government has been trying to prepare a nation-wide railway safety program, a safety organization, and a Safety Act. To construct a nation-wide railway safety management program, system architecture was established.

There may be several factors influencing the safety performance of railway safety personnel. These include human psychological and physiological states, physical conditions about working environment, and workers' stress and fatigue etc. Some researches indicate that human personality is close connection with human error. This study focuses on the workers' personality which is one of psychological traits of railway safety personnel. Thus, we survey and analyze it for railway safety personnel-locomotive engineers, station employees, and train commanders-in Korean railway company. Through the survey that is designed to investigate eight safety personality factors from the questionnaires composed of seventy eight questions, we study the workers' personality factors related to railway safety according to affiliated offices, operations, age, and working years. Finally, after categorizing survey results into sixty six patterns, we explain an example to show a corresponding worker to the pattern result.

This study proposes SMS(Safety Management System) improvement of domestic railway by intensively comparing railway safety system overseas to reinforce domestic railway safety. UK railways well known the well-organized railway SMS has brought up safety issues on their process of private management. With this process, also, domestic SMS improvements is requested by increasing sense of the safety for general public. This study expects Korean railways to become a well-organized that as removing insecure factors of domestic railway based on result comparing and analyzing the manual, factors and requirements of guideline for internal and external SMS.

Railway safety is one aspect of the transport service quality delivered to passengers, employees and third parties. To improve safety by a cultural shift from a deterministic to a risk based approach, European Railway Agency (ERA) introduces common and transparent methods to monitor safety performance and set targets and establishes safety management systems. The objective of this study is to review the common safety performance management method of the ERA(European Railway Agency) for it's application to the Korea railway. For this end, the risk assessment models were developed based on the accident scenarios and domestic railway accidents had been investigated and quantitative and qualitative analyses was performed using the developed information system.

Advanced Safety Management System(SMS) of Korea Railroad Corporation for risk management should be established applying contents-centered domestic standard according to Railway Safety Act and process-centered international standards suggested by Lloyd's Register Company. Besides, laws, regulations, guidelines and manuals which are optimized for each sector should be systematically integrated to strengthen the consistency of SMS of KORAIL. New safety regulations and guidelines for safety management/train operations/maintenance should be established according to the safety policy of KORAIL to boost effective field work by regulations, guidelines, manuals, etc. The advanced Safety Management System will lead KORAIL as a competent global enterprise with its boosted reputation in the international railway market.

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.

This study propose a model for railway safety evaluation with which the safety of whole railway system can be evaluated. The evaluation model is to generate a safety index which quantitatively represent the degree of railway safety. Safety index is proposed a function of three indexes; an accident index, safety management index, and safety culture index. This paper describes the first result from the study on the safety target which will be a key starting point toward the development of safety evaluation model. It is recommended that the safety target be composed of several sub-targets that are apportioned to constituent components. It is concluded that the classification of safety target influence on deciding components or attributes that constitute each sub-indexes; an accident index, safety management index, and safety culture index. Based on this study, a railway safety evaluation model will be developed in the next study.
