The railway is an important industry which quickly and safely transports a great deal of people and goods compared to other methods of transportation. Because there is not enough manpower in this field, professional engineers are urgently demanded. Although there are many people who apply for the Korea railway signaling professional engineer examination, they do not know how and what to prepare for it. This Paper analyzes the pattern of questions in the examination for the last fifteen years and the trend of the examination. The subjects which have been taught in railway related educational institutions for the last five years are also analyzed. This paper suggests some essential subjects that should be studied in order to show an easy way to obtain the certificate to those who prepare for the examination.

The Korean government, as of last year, is attempting to introduce a competitive system in the rail-market. However there are some pertinent issues which need to be addressed in order to select the best possible organization for optimum railway traffic control. As there are no standard guidelines in selecting an agency, objective evaluation factors need to be properly applied to ensure the best possible decision is made. Through literature review and various interviews with experts, appropriate criteria were selected to evaluate the suitability of each potential operator. As generally mentioned, both safety and efficiency play vital roles in the selection process but in addition, there are other factors such as security and fairness, which also need to be considered. The individual weight of these factors were calculated by the AHP, in which three groups of experts were interviewed to acquire their expertise. According to the results, as a potential operator, the score of a railway operating company and the management cooperation of railway is 2.75 and 3.85, respectively. In the future, in preparation towards becoming a competitive rail-market, this research is expected to assist in choosing the best party to control the rail traffic system.

Recently, countries such as Japan and France are actively using three-dimensional development of land to secure available land. In Korea, too, the lack of available land within cities is a major problem, and in particular, the problem of decline due to disconnection due to division due to the railroad is emerging. As a solution to this, interest in three-dimensional development is increasing day by day, but the application or legal effectiveness of the concept is still lacking. Therefore, in this study, assuming that the Gyeongbu Line railway in Busan is underground, we attempted to apply the type of multi-dimensional development appropriate for each region to the land that would be created, and to predict how much it would contribute to urban competitiveness by arranging the necessary facilities for each part. To this end, we have developed an urban competitiveness index that can evaluate the layout of facilities by region, and since the range of the region is different from the existing evaluation indicator, it is judged that the three-dimensional development of the railway facility site can have a positive impact on the competitiveness of the city as a result of the prediction through a subjective survey.

For domestic urban railways, which have a 19.7% aging rate, a performance evaluation is necessary to establish capital improvement investment plans. The performance evaluation, which was recently enacted in the relevant law, points out the excessive time and effort for acquiring data and evaluation. This study developed a performance evaluation simulation prototype using a virtual reality (VR) method to use as training contents for railway performance evaluations. The practical use of the VR technique to reduce the working time under poor environment conditions was confirmed through a literature review. A survey and consultation were conducted for urban railway experts to determine the weight of the performance evaluation items and the facility breakdown structure. This information was utilized to develop performance evaluation sheets for simulation. Based on the evaluation sheet, a training content prototype that evaluates the performance of platform safety doors was developed using VR techniques with HTC VIVE equipment. VR simulation tests were conducted for six players, and the prototype was sufficiently advantageous for a visual confirmation of the facility information. The result is expected to be useful for engineers to understand the performance evaluation process efficiently before an actual performance evaluation of urban railway facilities.

In pursuit of the Trans-Korea Railway (TKR) project connecting the Korean peninsular by a rail link, it is critical that the two railway systems in ROK and DPRK are comparable in criteria and standards. Yet, there is substantial divergence of the construction criteria between the two sides, which hinders from conducting the TKR project as well as the railway modernization of DPRK. In this regard, study and comparison of the criteria are a prerequisite for mitigating the hinderance. This study investigated the laws and regulations relating to the railway technologies and construction and in particular conducted a comparative analysis of both railway systems with a focus on railway facilities such as track, structures, electric power and signaling. The results of this study will provide a useful information for the improvement of existing lines and the construction of new lines in DPRK.

Recently, the utilization of the BIM system has been extended to cost and resource simulation, visualized management of construction site information and application of augmented reality including basic 3D modeling. Therefore, various BIM functions are being developed for practical applications. However, since clear classification criteria and knowledge information of BIM functions are not sufficient for field engineers, it is difficult to identify the necessary BIM functions for a construction project. This study suggests a BIM function breakdown structure considering the individual functional properties and a process model that can be ordered by applying BIM in a railway construction project. The proposed delivery model is used to obtain a practical utilization of BIM by analyzing features applicable to railway construction projects; model is verified using a case project.

철도시스템은 시설, 차량, 역사, 전기, 신호통신 등 거의 모든 분야가 통합되어 상호 유기적으로 동작함으로써 안전하고 신뢰성 있는 운행을 가능하게 한다. 특히, 철도에 처음으로 컴퓨터 시스템을 도입한 열차운행제어 설비인 관제시스템은 선구를 운행하는 모든 열차에 대하여 중앙에서 원격 감시 및 제어를 수행함과 동시에 열차운행에 관련된 모든 정보를 취합하고 이를 각 분야별로 전송하여 열차 운행의 정시성을 보장하는 중요한 설비이다. 따라서, 관제시스템은 열차운전 통제 및 감시의 일관성, 효율성, 적시성을 기하여 열차의 안전운행 확보와 지연을 최소화하고 있다. 이와 같이 열차운행의 중요설비인 관제시스템은 국가 보안시설로 평상시는 일반인의 출입이 금지될 뿐만 아니라 시스템적으로 외부로부터의 침입방지 및 보안 대책은 무엇보다도 중요한 현안이므로 관제시스템에 대한 보안 위협을 분석하고 이에 대한 보안대책 및 대응방안 등에 대하여 논의하고자 한다.

인터넷을 기반으로 하는 IT의 눈부신 발전과 더불어 언제, 어디서나, 시간과 장소에 구애받지 않고 인터넷을 사용할 수 있도록 하는 사회적 요구가 구체화 되고 있다. 이러한 요구에 부응하고자 국내에서는 200km 이상의 빠른 속도로 이동 중에 있더라도 초고속인터넷이나 방송 서비스를 제공할 수 있는 위성/무선통신 연동 초고속인터넷 시스템기술을 개발하고 있다. 본 연구에서는 위와 같이 개발된 연동시스템을 국내 고속철도(KTX)에 적용하여 서비스를 제공할 때, 관련 시설투자에 대한 경제적 타당성을 검토하고자 한다. 경제성 분석을 위해 현재 유럽에서 이미 제공되고 있는 고속철도 인터넷 서비스를 조사하였고, 국내 고속철의 특성을 감안하여 필요시설과 장비의 항목별 비용분석을 수행하였다. 해외 사례와 비행기 등의 다른 운송수단에서 예상되는 수요 및 요금 수준에 근거하여 고속철도 인터넷서비스 매출을 시나리오별로 산정하였으며, 각각에 대한 순현재가와 수익률을 도출하였다. 본 연구의 결과를 토대로 하여 위성/무선통신 연동 시스템 기술 개발에 대한 경제적 타당성을 도출할 수 있으며, 서비스 제공 시 마케팅자료로 활용할 수 있을 것이다.
