According to the Railroad Safety Act and section 42 of the Enforcement Ordinance, railway operators should conduct railway safety training regularly(6 or 3 hours per three months). But Overall Railroad Safety Audit conducted 2006 pointed out nonfulfillment of a regulations on railway worker's safety training to each of every 4 railway operators, which proved that the training management had not carried out properly. E-learning is used in various fields with development of Internet and IT technologies. It might be a good alternative tool for railway workers who is in shift working of the company 24 hours a day. Because it is difficult to collect those employees for training, e-learning could overcome obstacles of time and distance. In order to find out suitable e-learning model to railway sector, e-learning system for railway safety training has been researched through investigating e-learning technology and present railway safety training condition.

The considerable numbers of accidents have been occurred in railway industrials due to human errors by the railway operators, and we recognised that the design of work and the working environment influence the way people behavior. Human factors are a significant contribute to the occurrence of incidents, and that safety education and training guideline need to be designed to railway safety. In order to develop the education and training program guideline for railway operators, we performed investigation not only existing internal training programs and external railway and other industrial's training programs but also education engineering theory and expert interview. As a result we make up guideline to education and training program. The guideline are composed 10 section.

Despite a general acknowledgement of the importance of thorough needs analysis, a lot of training and education programmes are not considering needs analysis. When it is actually done, needs analysis is often trial and error or conducted in a fairly ad hoc manner. we are feel to needs for systematic approach to training and education needs analysis. We investigated the training and education needs for safety management system of railway manager. railway manager is just object to safety management team. we are develop to questionnaire design for safety management system in railway safety management. The questionnaire is separate to expert and a staff in charge related railway safety. We are discusses to primary needs safety management system in railway management team, and proposed to adapting training needs analysis method in railway safety.

Generally, in the railway vehicle the driving force of gravity happens by the high-speed running and the repetitive impulse cause the degradation and the malfunction phenomenon shows differently because the durability of each component changes according to the internal and external causes. The maintenance of propulsion control device which is played the very important role as to the stable service of the railway vehicle is greatly important among them. Therefore maintenance training propulsion control device simulator is needed to maximize learning through repetition and improve the maintenance practical skills training. This paper designed the railway vehicle running device with a miniature for the railway vehicle maintenance training and developed a propulsion control device simulator equipped the imitation steering wheel.

This paper describes the design methodology of the operator training simulator for power monitor and control system in the railway system. In power system, the purpose of energy management system was to monitor, control, and analyze the performance of generation and transmission system based on H/W and S/W. Network analysis applications provide a clear picture of power system characteristics using state estimation, power flow and short circuit analysis. In this respect, the operator training system in the railway system should be equipped with the methodology of these systems. First, the proposed database structure in the railway system was introduced. Then the overall structure of operator training system based on railway analysis applications was proposed. Finally, a methodology to verify the performance of the developed applications was described.

Railway accidents have caused tremendous casualties and loss of property. In order to reduce the rate of accidents, it is important for the railway operators to elevate their recognition and give effective training as a safety education and training. Through the previous study, we developed regulatory guidance for developing safety education and training program. Then, three educational technology specialists verified it primarily. In this paper, we investigated present condition for running education and training system of domestic railway through result of In-depth interview. And we verified actual reflection through result of Checklist. Finally, improved regulatory guidance for developing safety education and training program was suggested in this study.

Operator training simulator, within a training environment designed to understand the principles and behavior of the railway system with respect to operator's entries and predefined scenario, can provide a very strong benefit in facilitating operators' handling undesired operations. This simulator consists of computer system and applications, and the purpose of applications is to generate the power and voltage and analyze the AC substation and DC railway, respectively. This paper describes a novel approach to the new techniques for AC/DC hybrid simulation for the operator training simulator in the railway system. We first propose the structure the database of railway system. Then, topology processing and power flow using a linked-list method based on the proposed database, full or decoupled newton-rapshon methods are presented. Finally, the interface between the analysis for AC substation using a newton-rapshon method and the analysis for DC railway system using a time-interval power flow method is described. We have verified and tested the developed algorithm through the extensive testing for the proposed test system. To demonstrate the validity of the developed algorithm, comparative simulations between the proposed algorithm and PSS/E for the test system were conducted.

철도사고의 발생 확률은 적지만 한 번의 사고로 인하여 피해가 막대하고 빠르게 확산되는 특징이 있다. 이러한 예상치 못한 철도사고 예방을 위하여 열차안전운행의 최일선 접점에 있는 기관사의 역할은 무엇보다 큰 비중을 차지하고 있다 할 것이다. 철도안전법 시행 이전 기관사 양성은 각 철도운영기관에서 자체적으로 정한 자격기준, 교육기간, 실무수습을 거쳐 양성하였으며 동일차종을 운전하는 기관사 양성에 있어 철도운영기관 별로 각기 다른 기준으로 선발 교육함에 따라 철도차량운전자에 대한 양성 관리가 체계적으로 이루어 지지 않았다. 철도안전법 시행으로 철도차량 종류에 따라 면허의 종류를 분류하고 전문교육훈련기관을 지정하여 일정한 교육을 이수한 후 제3의 평가기관을 지정, 평가토록 함으로써 일정 수준이상 득점을 해야만 면허가 발급되는 체제를 갖추게 되었으며 교육훈련기관과 평가기관을 분리하여 운전자에 대한 능력을 객관적으로 검증할 수 있도록 하였다. 교육대상자에 따라 과목별 이론교육 시간을 달리 배정하고 실기교육의 대부분을 차지하고 있는 운전시뮬레이터의 취급시간을 최대한 확보하여 철도차량운전자의 자질을 극대화하는 교육프로그램이 되도록 설계하여야 한다. 본 논문을 통하여 면허취득을 위한 교육훈련의 효과를 극대화 하고 실용적인 교육을 위하여 필요한 제반 여건에 대하여 국내외 면허 교육훈련을 비교분석을 통하여 현행 제도의 문제점 및 개선방안에 대하여 연구하고자 한다.

Artificial neural network has been used for damage assessment by many researchers, but there are still some barriers that must be overcome to improve its accuracy and efficiency. The major problems with the conventional neural network are the necessity of many training patterns for neural network teaming process and ambiguity in the relationship of neural network structure to the convergence of solution. In this paper, the PNN is used as a pattern classifier to detect the damages of the railway bridge using dynamic response. The comparison between the mode shape and the natural frequency of structure as training pattern is investigated for approriate selection of the training pattern in the damage detection of railway bridge using the PNN.
