According to Railway Safety Act, Korea Transportation Safety Authority (KOTSA) has been entrusted with 'Integrated Railway Safety Audit (IRSA) and has implemented the safety audit to the Railway operation agencies such as Korea Railway (KORAIL) and the Railway 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 Railway operation and facility agencies by checking synthetically their performance of safety duties with sincerity according to the Railway Safety Act. Even though newly introduced IRSA is conducted smoothly, it is necessary to study the methodology and criteria of the state's safety audit system. The purpose of this paper is to improve the efficiency of IRSA by the comparative research between IRSA and other similar safety audit system and to establish the consecutive improvement concept of IRSA. Second purpose is to confirm the effectiveness of IRSA by the analysis of the relationship between audit results and the safety level of the rail operation agencies.

This paper insists that the accessibility and transfer facility has also to be included in railway investment because railway mode can not be, what is called, a door to door service. At present those facility are not included in the railway investment with them in negligence. Since those facility is not treated with railway system there is no room to get a budget from the central government. This paper suggests that all the measurements have to be implemented, based on the LOS (Level of Service) of accessibility and transfer at railway stations. The LOS has to be as low as reasonably practical (ALARP) which can be derived from the consensus between government and citizens. Also, a couple of procurement methods are suggested for accessibility and transfer facility separately. Finally, improvement of regulations are also suggested.

Large scaled railway freight transportation facilities in harbors are located in Busan port and Gwangyang port. The port rail depot plays an important role as the departure and destination function of railway logistics. However, presently, it is not relatively vitalized because it is not reflect the railway freight transportation's characteristics such as scale of railway tracks or yards area. In addition, even if port rail depot is vitalized, processing capacity is already saturated. Therefore, it is difficult to increase rail transport quantity. To activate railway container transportation business, it is very necessary to recalculate the facility size of port rail depots. Focused on the Busan new port rail depot, this paper analyzes the problems of port rail depot facility that has currently opened and finds some alternatives to resolve them.

This study focuses on developing railway facility charging scheme and more understanding of its corresponding regulations, which is to be utilized as a principal guideline toward a railway competitive market in future. European countries where railway competition is already in place have referred as case studies. The study first defined what the railway facility charges are based upon a spatial concept, railway networks with links and nodes. There are two types of charging: first is on railway tracks which are identical to links, and another at stations which are identical to nodes, such that the railway facility charges become a summation of track charges and station charges covering all the railway networks. Next, we have identified what the objectives of imposing track and station charges are, including factors being able to reflect each objective. 6 objectives are proposed as for the track charges, and 3 objectives as for the station charges. The factors found are accordingly belonged to the objectives. In the end, relevant regulations are compared with the European regime to diagnose what further requirements or/and principals have to be guided into them. In summary, both charging scheme and the direction of regulation updates can be utilized in setting an appropriate charging scheme and corresponding regulations to ensure fair competitions.

Rail network authority have to do the safety ensuring activities including the maintenance of railway facility, integrated performance verification between the facilities and related rolling stock and safety inspections, etc. When constructing the new lines or revising the conventional lines, full system commissioning should be done before the revenue service with railway operator. To develop the optimal full system commissioning model, the status of domestic and foreign railway facility and railway accidents are analysed and the problems of the safety management are derived. As one of countermeasures for the problems, the procedures and criteria for the full system commissioning are developed.

Purpose: This study investigates human error accidents in the Korean railway sector, emphasizing the need for systematic management to prevent such incidents, which can have fatal consequences, especially in driving-related jobs. Research design, data and methodology: This paper analyzed data from the Aviation and Railway Accident Investigation Board and the Korea Transportation Safety Authority, examining 240 human error accidents that occurred over the last five years (2018-2022). The analysis focused on accidents in the driving, facility, electric, and control fields. Results: The findings indicate that the majority of human error accidents stem from negligence in confirmation checks, issues with work methods, and oversight in facility maintenance. In the driving field, errors such as signal check neglect and braking failures are prevalent, while in the facility and electric fields, the main issues are maintenance delays and neglect of safety measures. Conclusions: The paper concludes that human error accidents are complex and multifaceted, often resulting from a high workload on engineers and systemic issues within the railway system. Future research should delve into the causal relationships of these accidents and develop targeted prevention strategies through improved work processes, education, and training.

The railway crossing is very dangerous because the track intersects with the road there. Thus, The laws were designed for safety of the railway crossing and they are classified as to the acts for the road and the railroad. For safety of the railway crossing, there are 'Road/Railroad Crossing Improvement Promotion Act', 'Enforcement Decree of Road/Railroad Crossing Improvement Promotion Act', 'Rules on Construction of Railroad', 'Rules on Safety Standards of Railroad Installations', and 'Enforcement Ordinance of Cable way/Railway Track Act' in the acts for the railroad and there are 'Road Traffic Act', 'Enforcement Ordinance of The Road Traffic Act', 'Ruled on Structure and Facility Standards of The Road', 'Rules on Structure And Facility Standards Of The Rural Road' and 'Rules on Structure and Facility Standards of The Installations for Bicycle' in the acts for the road. Both the acts for the road and the railroad have standards for the structure of the railway crossing. However, they have different standards. Besides, they don't have standards for new facilities which were recently installed for safety of the railway crossing. Therefore, we suggest new standards for safety of the railway crossing.

Disaster management system should be built for minimizing damage factor that affects to construction facility from natural disaster. It could be classified by three categories such as disaster prevention, damage survey and recovery phases. For an integrated disaster management system, a disaster information classification system(DICS) is necessary for the reasonable disaster information management. This study suggests an integrated DICS that includes disaster type classification, facility type classification and information type classification for disaster management service. The applicability of suggested DICS is verified by railway facility and the research result could be used as a basic information system for national disaster management system.

Much research has been actively done so far on the inconvenience of each urban railway station; however, Research is on importance factor analysis on transfer facilities by considering characteristics of railway stations is relatively insufficient. In this study, a novel method of finding causality between transfer facilities(movement, information, comfortability, etc,) in terms of demands and platform types is provided by using SEM(Structural Equation Model). The results of SEM analysis show that a large demand transfer station if combined with island and segregate platform types, has a higher importance factor with respect to information facility, movement facility position and comfortability. In addition, a medium demand transfer station if combined with separate and separate platform types has a higher importance factor with respect to information facility, movement facility and comfortability.

As the Reliability Centered Maintenance(RCM) is being studied, maintenance tasks can be performed effectively through the Risk Priority Number(RPN) evaluation about the components in the system. The RPN is usually calculated through arithmetical operations of three values, Severity, Occurrence, and Detection for each facility. This RPN provides information that includes risk level of the facility and the priority order of maintenance tasks for facility. However, if there is no sufficient historical failure data, it is difficult to calculate the RPN. In this case, historical failure data from other sources can be used and apply this data to korean railway system. In this paper, it is proposed that a new methodology to model the failure rate as a fuzzy membership function. This method is based on failure data from other sources by means of the fuzzy theory and the expert opinion system. And considering assessment tendency of each expert, distortions that happened when the failure rate of facilities is estimated were minimized. This results determine Occurrence values of facilities. Taking advantage of this result., the RPN can be calculated with Severity and Detection of facilities by using the fuzzy operation. The proposed method is applied the rail-way power substation.
