In response to the global warming crisis, the Kyoto protocol was established by major developed countries in 1997. The Paris Agreement, which imposes a carbon reduction obligation for both developed countries and developing countries, was signed in 2015. Regulations and efforts to reduce greenhouse gas emissions accordingly have been implemented. In this study, we analyzed the reduction of carbon emissions computerizing of the traditional project management system for efficient railway construction at Korea Rail Network Authority. We suggest a model that measures two major effects of carbon reduction, stemming from transportation and from a decrease of paper use. In this paper, we calculate the amount of carbon reduction and the economic effect of carbon reduction with application of the construction project management system at Korea Rail Network Authority. The model and methodology in this study are expected to be helpful to measure the carbon reduction performance for similar e-transformation.

Studied was a strategic plan for the Korean High-Speed Train system to penetrate the Chinese railway market in exchange of the technology of KHST. Firstly, taken was a glance at Chinese Government plans to extend total length of his railway lines and to construct the Beijing~Shanghai high-speed railway line. Then, disparity of railway technology in Korea and China was reviewed. From the review, SWOT Analysis were carried out to penetrate the foreign markets. Countermeasures to cope with SWOT were also considered. Strategical governmental supports and the establishment of the special organization to be in charge of penetration of KHST into foreign markets were proposed. Finally, also proposed was the transfer of KHST technology to Chinese counterparts in exchange of tangible benefits for Korean side. The benefits may include (1) adoption of KHST as the type of rolling stock for the Beijing~Shanghai line, (2) guarantee of participation in the project and royalty for the KHST technology used for the future high-speed railway line construction, (3) prior written approval and partnership when making its way to third country, and (4) participation of Korean construction companies in Chinese railway construction project, etc. Adoption of KHST in China indeed gives chance to integrate the high-speed railway network after reunification of Korean peninsular, and enhance the economic ties between two countries.

In order to promote economic cooperation and future reunification in Korean peninsula, this study is conducted to initiate a reconnecting plan for north and south Korean railways. When practical works to interconnect two counties' railway systems begin, the differences of railway systems such as rail track, railway facilities, communication systems, electrical power systems would be emerged as barrier. In this paper, to solve this problems, plan for the secure system-operational technology is presented. It also could be used for shaping the national transport network and constructing railway operating systems.

Compared with other transport means, safety and timeliness are the merits of railways. Unexpectedly when accident happens, much time and human strength are required to cope with the accident. And for swift recovery, systematic rehabilitation is needed. Recently using MTS(Moving picture Transmission System), we can perform accident rehabilitation and recording work efficiently. MTS is the device that transmits continuous picture information from accident field to control center. e are developing the appropriate system to railway situation to make use of the existing information communication technology, processing technology of video-tex, super high speed transmission technology through fiber-optic, copper cable and network description of information Technology, etc. If these communication-based can technologies are applied to railway system, railway managers can control the accident by inspecting the picture of accident field and can contribute to the safe train operation and the improvement of railway management. In this paper, we investigate the connecting methods when optical fiber is used for moving picture data transmission of train accidents, and its problems. And, we validate MTS's performance through about 28km section of field test.

A few of new and large cities have been developed and developing at some areas surrounding Seoul, a capital city of Korea. Thus, commuters from new city to downtown are considerably increasing and the present network of road and railway will be short of transportation capacities. A special problem is that new cities are far from downtown than pre-existing new cities and the entering to downtown is required to a considerable time and cost. Therefore, a new conceptional transportation system has to be substitute with old-fashioned road and railway. This paper presents the feasibility of the deep & high-speed nonstop railway which is able to access to the downtown with ease and fast from new city. If the railway is located under deep position, indemnity cost of land will be notably down. If the railway runs with high speed and has a nonstop concept, the access time to downtown will be remarkably short.

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.

Keep pace with economic development, the quality of transportation means such as railway, road, harbors has changed and those changes have affected to economic activities. It means that economic development and the changes of transportation quality have an inter-systemic relationship. So to speak, transportation means are major factor of national economic activities to implement economic and consumption activities by promoting supply of goods through the network between regions and industries. Currently, it is needed to connect railway and road between South and North Korea due to the economic cooperation of two sides and meeting of separated families based on the peacemaking mood. Moreover, to connect to T.C.R. and T.S.R. route will contribute to save time and cost of transporting freight to Europe comparing with shipping when South-North railway is connected. The possibility and method of connecting railway between South and North Korea will be introduced in this paper.

Recently the railway safety is very important issue in Korea because there are lots of changes like the separation of operation and facility of national rail network, the inauguration of high speed train and Daegu subway fire accident. Railway safety management system is based on risk assessment of rolling stocks, electrical system, signaling, operation & maintenance and human element. With this process, railway risk will be reduced as low as reasonably acceptable level. Through risk assessment on accident data, this study predicted the current risk level of railway electrical system and presented the proper safety ensuring measures.
