본 연구는 박근혜 대통령의 SRX(실크로드 익스프레스) 구상과 남북 및 대륙철도 연계를 앞당길 수 있는 실현방안으로서 기존에 검토되었던 남 북 러 가스관(PNG)사업의 천연가스를 철도를 통하여 수송 할 수 있는 방안에 대한 기초연구를 실시하였다. 이를 위하여 남 북 러 가스관(PNG) 사업의 추진현황과 남 북 철도현황에 대한 자료를 수집 정리하였다. LNG의 철도수송 가능성을 검토하기 위해 국내외 LNG 철도수송 사례를 검토한 결과 일본과 중국의 경우 LNG 탱크컨테이너를 이용한 철도수송이 이루어지고 있고 한국의 경우 LNG 탱크컨테이너 개발 및 철도운송 시범사업을 통해 철도수송의 안정성이 검증되었다. 연간 750만톤의 천연가스의 철도수송을 위한 운송노선과 화물열차 운행방안 등에 대한 기본방향을 설정하였고 LNG의 원활한 철도수송을 위한 인프라와 운영분야의 선결사항에 대해 제시하였다. TKR~TSR간 LNG 철도수송 사업은 기존의 남 북 러 가스관(PNG) 사업을 대체하는 별도의 사업이 아닌 SRX(실크로드 익스프레스) 정책의 조기실현과 유라시아 대륙철도 연계를 위한 상징적인 사업으로서의 의미를 가질 수 있으며, 남북철도 연계시 LNG 뿐만 아니라 컨테이너 및 벌크화물(석탄, 광석 등)의 대륙수송을 위한 상징적인 철도수송 노선을 확보하는데 보다 큰 의미를 부여할 수 있다.

The government have plans to improve the railway transport capacity and transport hub for the sustainable national transport and logistics system. Specially, there are much efforts to improve transportation capacity such as high speed transportation of rail freight, enlargement of BT train, development of double stack train, etc. between railway transport hubs. If the transport capacity between railway logistics hubs is increased as planned, we must increase the handling capacity of railway hub terminals. But there are limits to enlarge the terminal infrastructure because of investment scale, location circumstances and urban development plans. To ensure the capacity, with the minimum required enlargement of infrastructure, it is necessary to extremely increase the efficiency of terminal operations. For improving the efficiency, we have to introduce the efficient terminal operation systems based on u-IT and operation optimize technologies. In this paper, we analyse the issues and problems of railway terminals(including ICD) and suggest the concept of intelligent railway terminal and the construction components of technology.

The LIM can be used as a transport system with wheel structure. The structural tolerance cause the airgap unbalance and that effects on the LIM performance. The effect of airgap unbalance on the motor performance such as thrust force, velocity and armature current are investigated by using Finite Element Analysis (FEA). From this numerical works, it is known that the airgap unbalance almost does not effect on the motor performance and LIM for transport system is robust to the structural tolerance.

Seoul Metropolitan Rapid Transit Corporation - which is operating the subway lines No. 5, 6, 7 and 8 of Seoul's subway - has been operating a variety of motor cars and rail inspection vehicles to transport workers and materials into the tunnel at night after the daily revenue service for the maintenance of tunnel structure and track. However, the air quality in tunnels has been contaminated due to the operation of diesel engine cars, and rail inspection vehicles are now having higher chances of risks since the lightweight vehicles made with aluminum bogie became too obsolete. In this study, MRT type eco-friendly electric multi-inspection car has been elaborated for the purpose of improvement of tunnel environment and replacement of motor cars and rail inspection vehicles.

In this study, unattended Light Rail Transit System (K-AGT) is a general-purpose standards safety requirements of IEC 62267 based System Engineering Process (SEP) was used. Functional analysis and physical architecting for each requirements through the vehicle was classified into sub-systems, design was analyzed in terms of SE. The analysis of the proposed system engineering process, unattended train operation (UTO), driverless train operation(DTO) design of the safety measures to be used as the basis is studied.

Effort has been given to improve demand forecast methodology of rail system since it can have great impact on project evaluation of rail system investment. However most of demand forecast softwares developed in western countries where concerns have been provided mostly to private transport and they should be updated in order to reflect our country's situation accurately. Therefore, this paper aims, especially focusing on rail system, to do comparison analysis of oversea's passenger demand forecast softwares and provide some ideas to develop the updated demand forecast system which enables to reflect our country's situation accurately. Main conclusions are that we will need to have well described model for real situation. So we will have to study for these aspects for travel demand forecasting system and develop the package architecture.

In order to transport cargo rapidly and safely from the trans-Korean railway to the trans-Siberian railway having a different gauge, a gauge-changeable freight wagon can be used. Because the wagon is expected to run in South Korea, North Korea and Russia, it should have good dynamic performance in these railways. In this paper, the dynamic characteristics of a gauge-changeable freight wagon was analyzed numerically using ADAMS/Rail in each condition of the railways having different gauges and rail profiles. The wagon makes use of load sensitive friction damping and has highly nonlinear behaviour, which is modeled in detail as the full nonlinear dynamic model. It is shown that the running behaviour of the wagon is sensitive to changes in the rail gauge and profiles, however the assessment quantities from the point of view of safety, track fatigue and running behaviour are less than the limit valves.

Recently metropolitan local governments is actively introducing urban railway's expand and light rail transit as a means of new transport system. DC electricity feeder system operating in the domestic urban railway is typically a feedback circuit consisted of the contact wire and electric railway vehicle via rail. But stray current is to be defined as a current flowing on a structure that is not part of the intended electrical circuit with respect to a given structure. Stray current is generally results from the leakage of return currents from large DC traction systems that are grounded or have a bad earth-insulated return path. At the place where the current leaves the rail and metallic structures, electrolytic corrosion may take place. This paper presents comparison analysis of field test methods based on criteria of electrolytic corrosion protection of buried metallic structures adjacent to DC traction systems.

Korea has been at the forefront of efforts to enhance international cooperation in transport and communications within Northeast Asia. This effort is driven not only by the benefits that could accrue to the Korean Peninsula but also to all nations in the region. Mutual cooperation within Northeast Asia would reduce transport and communications costs and provide the basis for a regional transport and logistics network. Before progress can be made towards an integrated transport and communications system in Northeast Asia, however, there is a need to evaluate its prospects, outline a visionary plan, and detail a preferred strategy. The strategy to develop the Korean Peninsula as the gateway for Northeast Asia should harmonize with the region's common transport (and communications) policy The strategy adopted by South Korea is focused primarily on the development of an improved logistics infrastructure that would be extended to North Korea upon reunification. The seaport and airport developments In Korea will have to be supported by improved access to planned high-speed railways, expressways and freight distribution centers that, in turn, are to be integrated with new telecommunications and computer technologies. The benefits from these improvements will be lost unless existing government monopolies controlling seaport, airport, rail, road and expressway developments are commercialized to ensure that the price of transport reflects its actual cost. Technical harmonization between different modes should be promoted to facilitate efficient intermodal transport between the Korean Peninsula and the rest of Northeast Asia.
