Reduction of $CO_2$ emission is one of major issues in the whole industries, especially transport system. Railroad companies in the advanced countries such as EU, Japan, etc. have made great efforts on the improvement of their systems including energy sources, operational efficiency and PR of achievement resulted. Recently, to emphasize the environment-friendly characteristics of the railroad as public transport, the importance of PR is emerging. The achievements were listed in annual, sustainability and corporate responsibility reports. And the superiority of railroad in $CO_2$ emission can be confirmed in web sites and simple advertizing materials. In this study, we proposed the PR programs of achievement and ongoing works in Korean railroad through the case studies on web-based and off-line programs of railroad companies in EU and Japan.

The Incheon International Airport Express(I'Rex) is the railroad that connects Incheon International Airport, Gimpo Airport and Seoul Station. I'Rex is now under construction, and it will be connected to Gimpo Airport by 2007, to Seoul Station by 2010. However, there has been no discussion on how th connect different routes of railway Systems. Therefore it seems likely that rail passenger demand will be lower than that of limousine bus. Therefor, this paper proposes 4 effective connecting methods for I'Rex - (1) Shuttle transport, (2) Short-distance connecting transport (Inside I'Rex, Seoul Subway Line 9, 'Han-River line') (3) Mid-distance connecting transport (Jung-ang, Tae-baek, Young-dong line) (4) Long-distance connecting transport (Korean Train Express (Korean high speed railroad)) These methods can increase the connectivity of I'Rex with existing railroads and the competition power of I'Rex against a highway.

The railroad freight transport has great merits that can transport mass and specific items(dangerous goods), but it takes a long time because of low accessibility to the logistics facility and the complex process of loading freight in middle station. This paper analyzed volumes and characters of each railroad freight item, and was carried out the effect of applying E&S system to Gyeongbu line containers to find the method of reducing transport time and effective container transportation. As a result of Cost-Effectiveness analysis, the block train(B/T) is reducing transport time more about 1~2 hours. The road congestion cost is saving about 2.2 billion won. And due to skipping work of organizing train, personnel and equipment expenses savings expected about 9 billion won. It is expected that the E&S system enhances the container transport service and has an effect positive influence on making a efficient method of transport. But It is necessary to estimate pre-feasibility of applying E&S system that the standard of estimating cost and benefit is required further examination.

철도투자의 필요성은 누구나 공감하고 정부에서도 지속 투자를 시행하고 있으나 철도의 화물수송 분담률은 오히려 감소하고 있는 실정이다. 이는 다빈도, 신속, 신뢰성을 요구하는 즉시인도(Just In Time: JIT)와 문전수송 (Door to Door) 등 고도화되는 고객의 욕구를 충족시키지 못하였기 때문이다. 결과적으로 지난 114년 동안 구축된 철도인프라 시설이 점점 효용가치를 잃어 가고 있다. 이에 본 연구에서는 철도수송의 근본적인 문제점인 문전수송(Door to Door)을 해결하지 않고는 도로수송을 철도수송으로 전환하는 것은 어렵다고 보고 도로에서 철도로의 전환(Modal Shift)이 가능하도록 철도수송 시 철도화물역에서 최종목적지로 환적없이 화물자동차를 직접 운반하는 피기백(Piggy Back)시스템이라는 신개념을 정립함으로써 문전수송(Door to Door)에 의한 철도화물 수송의 경쟁력 확보 및 활성화 방안을 제시하고자 한다. 피기백(Piggy Back)시스템 적용방안으로는 짧은 기간 내에 적은 투자비로 즉각 시행이 가능하도록 지난 114년 동안 구축된 기존 철도인프라를 활용하는 정거장 배선계획을 제시하고, 이에 따른 세부 열차운행방안 및 피기백시스템 도입시 건축한계 등 기술적인 검토를 시행함으로써 연간 국가 물류비를 약7조원이상 절감할 수 있는 획기적인 방안을 우리나라 최초로 제시하였다.

최근 기후변화에 따른 이상 기상현상이 증가하고 있는데, 특히 동절기의 혹한은 승객의 열적 쾌적성을 크게 저하할 우려가 있다. 이에 본 연구에서는 철도차량 실대형 환경챔버를 이용하여 저온 조건에서 철도차량의 난방장치 가동시 객실 내부의 온도변화 및 분포를 알아보았다. 실험결과 난방시스템 가동 직후에는 객실 내부온도가 급격하게 증가하였으나, 일정 시간 경과 후에는 더 이상 증가하지 않았으며, 객실의 위쪽이 아래쪽보다 온도가 더 높게 나타났다. 이러한 결과들을 통해 승객의 온열 쾌적감 저하를 최소화할 수 있는 방안을 제시하고자 하였다.

In 21th century, high oil price and environmental pollution appeared by serious social problem. It brought important change of logistics environment, and environmentally-friendliness and sustainability are emphasized. In spite of that railroad has high energy efficiency and environmental-friendliness to advantage traditionally, there is still transport division rate of railroad in declining tendency as investment policy that is concentrated on road and insufficiency of social realization about environmental problem. The construction of environment-friendly transport system and the reasonable role sharing between modes of transportation are important. Transportation policy of Korea is presented through plans to constructs efficiently and manages national transportation system. In this study, examine development process of national railroad logistics plan with logistics environment change, and proposes the following ways to development of railroad logistics policy.

Purpose - The Korean government has devised intermodal transportation policies and granted subsidies to shippers and logistics companies that made a conversion of transportation means through the policies. This provides support by expanding the complex uniform railroad transportation and overhauling the deteriorated railroad facilities. As for 2013, however, the freight transportation percentage of railroad was 4.5% in tons and 8.5% in ton kilometers. Meanwhile, since the 1990s, developed countries such as the U.S. and Europe have been trying to expand intermodal freight transport with a legal and institutional support to build a logistics system corresponding with social and economic environmental changes. In this study, I set out to examine the effects of the intermodal freight transport policies in the EU and the U.S., and to explore the direction of setting up a rail intermodal transport system in South Korea. Research design, data, and methodology - The paper used a qualitative research methodology through the literature review. First, was an overview of Intermodal transportation in the EU, U.S. and UN. Second, it describes the development of transport in Europe and the U.S. with particular emphasis on intermodal freight transport. Third, it explores the direction of setting up a intermodal freight transport in South Korea. The last section contains concluding remarks. Results - As for the EU, it has been promoting integration between transport and intermodal logistics network designs while utilizing ITS or ICT and supports for rail freight intermodal by giving reduction to a facilities fee or subsidizing for rail freight in order to minimize the cost of external due to freight transport. On the other hand, as for the U.S., it has been made up of an industrial-led operating project and has been promoting it to improve accessibility between intermodal hubs and cargo terminals through intermodal corridor program, and an intermodal cargo hub access corridor projects, etc. Moreover, it has tried to construct intermodal transport system using ITS or ICT and to remove Barrier. As a result, in these countries, the proportion of intermodal freight transport is going to be the second significant transport compared with rail and maritime transport. An Effective rail intermodal transport system is needed in South Korea, as seen in the case of these countries. In order to achieve this object, the following points are required to establish radical infrastructure policy; diversify investment financing measures taken under public-private partnerships, legal responsibilities, improvement of utilization of existing facilities to connect the railway terminal and truck terminal, and enhancement service competitiveness through providing cargo tracking and security information that combines the ITS and ICT. Conclusions - This study will be used as a basis for policy and support for intermodal freight transport in South Korea. In the future, it is also necessary to examine from the perspective of the shipper companies using the rail intermodal transport, ie, recognition of shipper, needed institutional supports, and transportation demand forecasting and cost-effective analysis of the railway infrastructure systems improvement.

In the early 1990s, the market-orientation attracting a lot of attention as the implementation strategy of marketing is an effort to give customers a value and get sustained earnings in the market. In the previous studies, most of the studies on the market-orientation have focused on hotels, large companies and IT, so it was hard to find the study on railroad in the view of transport service. Thus, this study aimed to find out how marketing activities using transport service and a variety of products linked railroad are shared by group members and what effect the organized union of corporate culture has on business performance as market-orientation activity. Previously, the purpose of this study was to research whether the management system of a private enterprise based on market could be applied to the public enterprise like Korea railroad.

High speed railroad project management has been almost completed by starting operation of Seoul-Busan high speed railroad with the exception of a few constructing blocks currently in April, 2004. After Korea Rail Network Authority was established in 2004, it needs to develop new project management system for both conventional railroad construction and high speed railroad construction for domestic railroad projects, while it plans to invest in overseas railroad project for logistics innovation and improvement in passenger transport services on a large scale. Therefore this paper provides the method that we can adapt the project management system for high speed railroad containing experiences and know-how from construction of high speed railroad for both conventional railroad construction and high speed railroad construction or improve project management system for high speed railroad to use it as project management system for overseas railroad projects.
