The development of the TSR-TKR Network will be regarded as the most important step towards the realization of integrated regional transportation system. If the TSR-TKR is constructed, there may be a possibility for the TKR to be used for shipments to Europe relacing marine shipments that take place at present. However, major forwarders think that it will not be easy to ensure the economic competitiveness of the TSR-TKR route. In this study, we have analyzed the optimim route for integration of opreation line on TSR-TKR.

신도시 개발 등으로 대도시의 생활권이 확대됨에 따라 수도권 교통의 광역화가 지속적으로 진행되고 있어 대도시권내의 광역교통문제해소 및 혼잡비용 최소화를 위한 체계적이고 지속 가능한 장기 마스터플랜 구상이 필요하게 되었다. 이에 따라, 최근 경기도에서는 동탄 신도시와 서울 강남을 20분대에 연결할 수 있는 대심도 급행전철 사업을 구상하였다. 국토부에서는 경부고속철도 2단계와 호남고속철도 완공에 따른 선로용량 부족해소와 수도권 및 경기 남부 지역 주민들에게 고속철도 서비스제공을 위한 강남권 고속철도 노선(수서${\sim}$동탄${\sim}$평택) 건설이 필요한 것으로 "수도권 철도망 개선방안 연구용역(2007.12)" 결과를 발표하였다. 경기도에서 추진 중인 광역급행전철과 강남권 고속철도 노선이 중복됨에 따라 국토의 이용 효율성 향상과 국가재정의 효율적 투자를 위해 고속철도의 선로 여유용량을 활용한 광역급행전철 혼용에 대한 검토가 필요할 것으로 판단된다. 따라서, 본 연구에서는 고속철도와 광역급행전철을 혼용 운행할 경우 노반분야 및 E & M 기술조건, 중간역 계획, 열차운영계획 등의 분석을 통해 최적화된 혼용운영 방안과 사업비 절감효과 등을 제시함으로써 동일선로에서 이종의 열차가 운행됨에 따른 철도사업의 투자효율성 제고 방안을 제시하고자 한다.

우리나라의 주요 교역권은 아시아, 미주, 유럽 교역권으로 나눌 수 있다. 일반적으로 대량의 화물운송은 해상운송이 주를 이루지만 다른 지역과 다르게 유럽 교역권은 철도 운송이 가능하다. 또한, 중국의 성장으로 동북아 물류 중심지로서의 경쟁력이 약화된 우리나라는 지금의 경쟁구조와는 다른 방안인 철도운송에 주목할 필요가 있다. 이러한 배경 하에 본 연구에서는 한반도 종단 철도(TKR)와 시베리아 횡단철도(TSR)를 이용한 유럽 지역과의 운송 경로를 비교하여 경제성 분석에 주안점을 두었다. 분석의 요소로는 운송거리, 운송기간, 운송비, 추가비용을 중심으로 사용하였으며 분석 결과 6가지의 운송경로 중에서 TKR과 연계한 TSR(Route 1)이 경제적이라는 분석 결과가 나왔다. 따라서 향후 러시아 푸틴정부의 극동발전 전략에 대비하여 우리나라는 TKR과 TSR의 철도운송을 활용하는 것이 국가 경쟁력을 높일 수 있는 방안이 될 것이다.

Even though the existing train route controlling method, using track circuits, ensures the sufficient number of operation, it still has problems such as discordance between train numbers which was planned for operating and train numbers being operated on the track, and allowing only one train entering for one route. To solve those problems, we study and develop the Smart train route controlling system which uses the real-time informations of train positions. This system enables improve the coefficient of utilization in a certain train route controlling section, and the safety level of train route controlling, but we should ensure satisfying reliability of data about tracks operated by trains. In addition, there is a need to protect accidents caused by erroneous information of train position, by reflecting changes of tracks, for example maintenance, improvement, expansion of tracks. In this paper, we proposes and describes a developed program which required to change AutoCAD files to wiring diagrams, to generate them to data of tracks, to identify errors of those data, to construct the structure of necessary resource(s) for sub-systems of a train control system, and to provide simulations of data structure.

The rail sector, despite its potential for curtailing the present chaotic transport situation in Lagos, remains inefficient and underutilized. In spite of past initiatives and the current attempt by the Lagos State Government to provide a mass transit rail service in Lagos, the share of rail mode in the transport sector has not been encouraging and the railway plays an insignificant role in urban mass transit in Lagos at present. This paper sets out to assess the usage of the Lagos mass transit trains. Hence, the paper determines the passenger traffic flow along the rail route in Lagos and the number of passengers carried between 2000 and 2009 by the Lagos Mass Transit Trains (LMTT) with a view to assessing the usage of the present LMTT. This paper also discusses the historical development of Nigerian railway and describes rail transport in Lagos. Data were obtained through secondary sources coupled with review of literature. The result of this study shows that for a period of 10 years (2000-2009), Lagos mass transit trains carried a total of 9,870,101 passengers, which gives an average of 987,010 passengers annually. This suggests that the service of the Lagos mass transit train is grossly underutilized. However, LMTT contributes enormously to NRC by carrying 68.5% of the total passenger traffic of NRC between 2000 and 2009. In terms of passenger traffic flow along the route of LMTT, for a period of 1 year, Agbado station recorded the largest number of passengers (393,811), followed by Ijoko (163,652) and Iddo (120,787), while Iganmu station has the lowest number of rail commuters (16,919). This study also discloses that the major commodities hauled by Lagos district of NRC from Lagos to the northern parts of the country in 2007 are Cars, Cement, Billet and Wheat.

LRT(LAght Rail Transit) system is a new transportation system with new technique of an electric railway. Transportation ability of LRT is mid-scale of a bus and a subway, transporting 5,000-30,000 people per hour and direction. LRT automatically operates in the existing metropolitan railway and large-scale development areas or satellite cities with a fixed route and has a short interval that guarantees scheduled-time, safety and environment-friendly.

IN THIS STUDY, BASED ON THE TYPE OF HIGH SPEED RAILWAY TRACK VIBRATION CHARACTERISTICS WERE MEASURED AT KTX VEHICLE. KTX ROUTE BALLASTED TRACK HAS BEEN INSTALLED TOGETHER WITH THE CONCRETE TRACK. CONCRETE MUST BE TRACK IRREGULARITY THAN BALLASTED TRACK, VEHICLES VIBRATION VALUES THAT ARE SMALLER. ALSO, IN TERMS OF MAINTENANCE, CONCRETE TRACK IS KNOWN TO BE MORE FAVORABLE THAN THE BALLASTED TRACK. PHASE 2 IS THE KTX, DAEGU - BUSAN IS A SECTION OF CONCRETE TRACK. IN THIS STUDY, "KUUNG-BU HIGH-SPEED RAILWAY LINES" INSTALLED ON THE CONCRETE TRACK AND BALLASTED TRACK KTX FROM THE VEHICLE WHEN INSTALLED BETWEEN RAILS, SLEEPER AND BALLAST ON THE TRACK WAS MEASURED VIBRATIONS.

After rapid running is begun in domestic, problem by the train wind that was not considered at existent train running appeared. If the High-Speed railway business speed rises by 350km/h in the future, is going to become more big issue. This study conducts an experiment that measure in local about KTX train beside Gyeongbu High-Speed railway track about aerodynamics effect that happen by passage of train and analyzed. In case KTX II runs with the 350km/h speed, forecasted effect that get in the simple vertical surfaces parallel to tracks according to distance from rail center. Compared construction size with structural analysis in case do not consider with case that consider the train wind about soundproofing walls representatively. As a result, proposed wind load standard that apply at soundproofing walls design.

As a result of that the domestic railway technology has been progressed as times go by, the 1st and the 2nd steps for Gyeongbu HSR at the speed of more than 300km/h, were completed and Honam HSR - its operational speed is 350km/h - is under construction. Additionally, As a part of the expressization project for general lines, the Seoul-Chuncheon route at the speed of more than 180[km/h] is under construction and the Jeolla route is under design. At present, 11 countries (e.g. France, Germany, Belgium, Italy, the Netherlands, Spain, England, Japan, China and Taiwan) including Korea have high speed railways operated at the speed of more than 300[km/h]. As shown in the above, the domestic railway has high speed trains as good as those of countries outside Korea, but the schedule speed, which is calculated by dividing distance to destination by time, is lower than that of overseas trains. For overseas railway, the ratio of schedule speed to the highest speed is above 65%, while that of domestic railways is over 50%. It shows a significant difference between them. It is expected that the schedule speed improvement will increase the number of train operation and line capacities than now, so it shall achieve smooth transportation flow and improve the passengers' satisfaction. In this paper we describe the necessity for the improvement of schedule speed, by analyzing foreign cases related to the improvement of schedule speed in order to satisfy the increasing traffic demand.

한국은 1940년대 남북분단 이후 국제 무역 및 물류를 위해 해상운송에 의존해 왔으며, 현재는 북한을 경유하는 유라시아 횡단 물류를 위해 새로운 경로의 개발을 준비하고 있다. 이를 위해 극복해야 할 많은 어려움이 존재하지만, 한국은 아시아와 유럽 구간의 기존 해상경로보다 짧은 새로운 육상경로가 앞으로 더욱 빠르고 비용 효과적인 물류서비스를 통해 더 많은 교역을 가져올 것으로 기대하고 있다. 이와 관련하여 본 연구는 한국종단철도가 개발되어 중국 및 시베리아 횡단철도와 연결된 상황에서의 국내물류 변화를 미리 분석해 보고자 한다. 국내 물류시스템의 모델링을 위해 시스템다이내믹스 시뮬레이션 기법을 사용하였다. 시뮬레이션 결과 수도권과 가까운 의왕 ICD의 물동량은 증가하는 반면, 부산항의 물동량은 감소할 가능성이 있는 것으로 나타났다. 철도를 활용한 유라시아 횡단 물류의 성공을 위해서는 본 연구의 보완과 더불어 국내 물동량 처리 용량의 조정에 관한 후속연구가 필요하다.
