본 연구는 한국과 아시아 및 유럽간 국제 무역이 확대되어 감에 따라 국제 운송에 있어서 새로운 운송대안이 모색되어져야 할 것으로 보고 그 대안을 철도에서 찾고자 하였다. 특히 대륙횡단철도(KTAR)는 한국을 기 종점으로 유럽까지 잇는 세계 최장의 철도 노선으로서 그 실현가능성이 높아지고 있다. 본 연구는 이러한 변화와 가능성에 앞서 대응하고자 대륙횡단철도의 선택 의도에 대한 실증적 연구를 수행하였다 연구를 위해 운송수단 선택 요인으로 6개의 잠재변수(운송 서비스, 운송 비용, 운송 효율성, 철도에 대한 태도, 철도로의 운송수단 전환 의도, 대륙횡단철도 선택 의도)를 도출하여 이들 변수 간의 관계를 구조 방정식 모델링을 통하여 실증적으로 분석하였다. 구조 모형의 분석 결과 대륙횡단철도 선택 의도에 가장 큰 영향을 미치는 요인은 철도로의 운송수단 전환 의도와 철도에 대한 태도로 나타났으며, 그리고 이들 요인에 강력한 영향을 미치는 선택 요인으로는 운송 비용 요인임을 확인할 수 있었다.

2018년 9월 19일 남북정상의 평양공동선언에서 남북한은 철도 및 도로연결을 추진하기로 합의하였고, 이에 따라 2018년 12월 북한철도 현대화 사업을 위한 남북한 공동조사를 착수하였다. 조사 결과 선로상태는 운행이 불가할 정도로 심각하게 노후화되어 있고, 철도망은 주요도시를 잘 연결하는 구조로 되어 있는 것을 확인하였다. 따라서 새로운 철도망을 건설하기 보다는 기존 철도망의 노후화된 선로를 현대화하는 것이 타당하다고 판단되었다. 본 논문은 남북철도 연결에 대비한 상호운용성 및 철도사고 예방을 위한 안전성 강화를 위하여 노반과 궤도의 현황 분석을 통한 단계별 철도선로 개선 그리고 철도무선통신망 구축을 위한 철도통신분야 정책을 제안하였다.

To establish transportation system in railway focusing truly, we should plan route and invest continuously to consider the means of railway's functional sides. And it should be inter-modal system. Therefore this study concentrates on high-speed railway and considers the construct of transportation system in railway focus on the supplier aspect.

This article introduces a railway organizational change of the Swedish Railway Case written by Petra Stelling. Through the Swedish Railway organizational change case we know that issues such like functionalism vs. regionalism, dividing rolling' stock department, and separating divisions are solved in the organizational designs. Swedish experience could give some hints to Korail organization change efforts.

Railway bridge, contact of vehicle needs to design considering the running safety about the running train load of the railway bridge, ride comfort and dynamic safety. Also, upper structure of the railway bridge has to satisfy design standard about moving load(train). So, the railway bridge has to satisfy the requirement for vertical acceleration of the bridge deck, vertical displacement of the bridge and face distortion, which is suggested railway design standard in Korea(2011.5.). In this study, it was investigated and evaluated to the running safety about the running train load of the railway bridge, ride comfort and dynamic safety with railway design standard for steel composite(Steel Box Girder) railway bridge considering KTX, freight train and standard train load.

To maintain the stability during the operation of railway vehicle, the perfect installation of rail, namely the orbit as well as the performance of the railway vehicle itself is required. The orbit of railway needs the intensity and elasticity that stands the shock and vibration due to the weight of the railway vehicle enough, Also, the driving safety during the operation of vehicle should be guaranteed, comfortable feeling of the passenger should be maintained, and the influence of the noise and vibration to the environs should be minimized. Therefore, it is necessary to develop a program that calculates the change of construction cost according to the selection of railway orbit. This study introduces the orbit design automation program according to the selection of railway orbit, and discuss the principle and the way to use of the program.

Korea selected to introduce high-speed railway system from advanced countries in order to accumulate railway technologies and develop exiting domestic logistics system. After many twists and turns, we adopted to introduce France's high-speed railway called 'TGV'. Despite many difficulties along with trials and errors, it is expected that Korean high-speed railway will be brilliantly launched in April 2004, although it has been commissioned for multi-discipline tests. It is forecast that the opening of high-speed railway will bring us the epoch-making development of logistics system. However, what if there are really some problems in the operation of high-speed railway? We cannot consider and highlight only the positive aspects of our own high-speed railway. In terms of many challenging aspects we would face in the future, there would be some matters we must consider and point out in this opportunity. In this regard, the direction for developing high-speed railway stations requires the harmony between profitability and public benefits, which must involve compatibility with other traffice systems and practical policies to secure competitive edges.

Recently, Korean government demands that public sectors like railway construction should improve their management efficiency. It is necessary for railway construction supported by government budget to aim at the companywide management efficiency. The Balanced Scorecard (BSC) is known as integrated performance management framework that helps a company to translate strategic objective info relevant performance within an organization. This paper focuses on relationship between KPIs (Key Performance Indicators) used to measure the performance of railway construction industry and process KPT for BPM (Business Process Management). Also, the vision and strategies of the railway construction is introduced, and the CSFs (Critical Success Factors) and the KPI based on BSC is developed. Finally, this paper explores that there is a possibility to fulfill the strategic objectives of railway construction industry through the connectivity between KPI based on BSC and process KPI based on BPM. We explain the detailed procedures with an example of railway construction industry.

According to the Railroad Safety Act and section 42 of the Enforcement Ordinance, railway operators should conduct railway safety training regularly(6 or 3 hours per three months). But Overall Railroad Safety Audit conducted 2006 pointed out nonfulfillment of a regulations on railway worker's safety training to each of every 4 railway operators, which proved that the training management had not carried out properly. E-learning is used in various fields with development of Internet and IT technologies. It might be a good alternative tool for railway workers who is in shift working of the company 24 hours a day. Because it is difficult to collect those employees for training, e-learning could overcome obstacles of time and distance. In order to find out suitable e-learning model to railway sector, e-learning system for railway safety training has been researched through investigating e-learning technology and present railway safety training condition.

This paper describes the dynamic modeling of a railway vehicle when it is under braking force. It is important for the enhancement of braking performance to establish a proper dynamic model of a railway vehicle because the braking performance is affected by some dynamic forces generated by a railway vehicle when it undergoes braking. In this paper, a dynamic model for one vehicle is suggested to compute the dynamic behavior of a railway vehicle in the HILS(Hardware In-the-loop Simulation) system for the railway vehicle braking devices. To simplify the dynamic model, friction between a wheel and a rail is assumed that there exist only the static and the dynamic friction forces. Static friction coefficient is also assumed to be a function of the running speed. Some simulations are carried out with various braking forces, and the braking characteristics according to the change of the braking force are discussed. This study can provide some fundamental results to construct the HILS system for braking devices of a railway vehicle.
