To operate a border station between South and North Korea is one of the most important tasks for the future inter-Korean railway transportation. Currently, North Korea and China are operating three border stations each. Among them, a Dandong-Sinuiju route handles the most amount of transport volume and can be a model for the operation of South-North Korean border station. This Study is to suggest an efficient way of operating the planned South-North Korean border station and international railway transportation via the station. To that end, operation system at the border station between Chinese Dandong and North Korean Sinuiju was analyzed and the Train Operation Agreement made by the two Koreas was studied.

Green ocean is one of the main issues internationally. Most governments are leading the role in boosting the economy through creating new green market and establishing system of coping with increasing international environmental regulation. Green ocean, which is a solution for the environmental issue of global warming, is applied throughout the industry. Domestic transportation industry including railway is also developing technology for creating green ocean. Transportation must decrease energy consumption at running stages because it shows high environmental loads expecially on using stages during its life cycle. Therefore, There are some tries for developing technologies; new engine through alternative energies, hybrid and lightweight. Railway transportation can not be exception. it is intended for this paper to suggest the direction of manufacturing environmentally friendly railway vehicle through the global warming effect evaluation of several materials being applied to vehicle and comparison of the results.

현재 운영되고 있는 광역도시철도 시스템에서는 표정속도의 저하에 따라 평균 출퇴근 시간도 계속 증가하고 있으며 이는 도시철도 이용률의 저하와 타 교통수단 대비 졍쟁력 저하로 이어지게 된다. 따라서 열차의 표정속도를 대폭 향상시킬 수 있는 광역도시철도의 효율적인 급행화 방안이 요구되고 있다. 이번 연구에서는 가감속도와 최고속도 성능을 향상시킨 고성능 전동차 투입을 고려하여 급행과 완행으로 분리 투입시 획득 할 수 있는 시간 단축 효과와 경제성을 기준으로, 광역철도간 급행화 방안들을 제안 및 그 결과를 비교 분석하였다. 또한 대피선 설치를 최소화 할 수 있는 최적의 급행화 방안을 분석결과로 제안하였다.

Due to the fact that high speed railroad will be opened to traffic and TSR and TCR will be connected to Korean railroad network in near future, the efficient operation methods of Railroad freight transportation have been embossed as a matter of concern. But, it is true that the present level of our railway infrastructures and operation systems are still low. This study examines the freight transportation system and introduces new logistic service systems including network strategies and terminals which are haying developed overseas to increase the efficiency of existing railroad transportation system. In case of giving careful consideration to the new methods, it is expected that the high developed freight transportation systems will be applicable to our country.

철도는 육상수송수단으로서 18세기부터 사용되고 왔는데, 근대적 개념의 철도는 증기기관의 이용이 그 정의로 사용되며, 영국 북서부에서 Stockton & Darlington Railway가 증기기관차 운행을 개시한 것이 그 효시가 되었다. 체계화된 운행시스템을 가진 증기기관차 운행 전용철도로서는 영국의 Manchester & Liverpool Railway가 시작이다. 이러한 역사를 가진 철도는 각국에서 여러 가지 모양으로 발전되었고 시간이 지남에 따라 보존되고 있다. 특히 철도를 최초로 운영한 영국은 다양한 형태의 철도문화유산 보존체계를 가지고 있다. 또한, 아시아에서는 철도분야에서 가장 빠른 발전과 민영화 경험을 가진 일본도 체계적인 철도문화유산보존 시스템을 구축하고 있다. 본 연구에서는 영국과 일본의 양국 철도문화유산제도와 사례비교를 통해 우리나라에 주는 시사점을 살펴보고자 한다. 본 논문의 연구방법은 비교연구의 방식을 채택하였는데, 양국이 가진 법과 제도 및 운영사례 비교분석을 통해 비교와 시사점을 도출하는 방식으로 전개하였다.

The Korean electric railway is growing rapidly such as speed of 300km/h in high speed section and 230km/h in the conventional railway section. But, power supply failure occurs because of loss of contact, defective catenary system and high speed vehicle. Therefore preventive maintenance way based reliability has been applied. Typical example is the facility inspection method using trolley inspection system. But it is required differentiated inspection method to prevent problem such as inspection errors. In this paper, a study on the trolley sliding condition inspection system using monitoring techniques is performed for performance enhancement of inspection system. It proposed the efficient maintenance method through monitoring the deviation and height of contact wire after installing inspection system on the top of train which operates in the metropolitan area. Inspection errors were decreased by virtually monitoring the video of faulty facilities. Also those facilities were identified through the impact sound analysis and tests at the main catenary section.

Railway intelligent transportation systems and related Ministry of Land and rail operating agency's railway informatization planning of information technology, effective through the use of management strategies to establish or run to support the systematic informatization investment that you want to execute work in progress, during and yet the institutional informatization of operations mainly in the form of efficiency is Chinhae. Accordingly, in order to promote the details of the final challenge of providing real-time information and the usefulness of this information collection is clearly for the railway sector by function of the components is necessary to distinguish. In this paper, the details of the plan goals, promoting convenient rail-based real-time information, to promote optimal gohyoeuleul railways, railway safety and comfort, was defined as three. Selection of each goal, because the direction of vision and ITS around the railroad center of road users by highlighting the benefits of the railroad's traffic information center user switching, real-time delivery of information diversity (enhanced content) that can increase the capacity of line train operating systems, enhancing the safety management system introduced in the monitoring system and is a railroad crossing. Because urban railway project in accordance with the goal of decreasing the annual rate of the train support, and the average passenger wait time savings, increased future demand for railway, rail safety, including securing the expected effects may occur.

본 연구는 지역 간 철도인 중앙선 일부 철도역의 실태조사를 토대로 우리나라 지방 중소도시 철도역의 환승교통체계 정비방향을 논하였다. 현재의 환승체계에 무엇이 문제인지를 알아보고 이를 개선하여 보다 많은 통행자가 공로에서 철도로 수단전환을 하도록 하는데 일조하고자 하였다. 연구의 결과 지방 중소도시의 철도 이용자는 시내버스 등 대중교통 중심의 연계교통을 희망하고 있으나 현실은 그러하지 못하며, 따라서 앞으로 시내버스를 위주로 하는 연계교통체계 구축이 강조되었다. 또한 환승거리를 최소화하고 다양한 연계교통수단을 수용하기 위해 역 광장 등 시설정비 방안의 도출과 이를 시행하는 정부지원 필요성이 제기되었다.

The recent environmental protection trend requires more strict energy saving, therefore every transportation system should reduce energy consumption to the minimum value. High-efficiency operation system, energy saving and $CO_2$ emissions shall be addressed as important issue in railway system. These issues are the most essential factors of railway, compared to major public transportation system. Recently, saving energy in the electric railway system has been studied. For such new energy saving, the energy storage system is considered for saving energy. Energy saving is possible by efficient use of regenerated energy. Regenerated energy is recycled amongst vehicles by mean of charge and discharge corresponding to powering and braking of electric vehicle operations. This energy saving contributes to cut $CO_2$ to reduce greenhouse gas emissions. Recycling regenerated energy demonstrate significant effect on peak cut of consumption energy in railway substation. Absorption of excess energy avoids regeneration failure due to high traction voltage. Therefore, the energy storage system is needed to be adopted to use regeneration energy when the vehicle is braking.
