As of July 1999, 1,185 lomocotives(excluding metropolitan area electric locomotives) are in Korean National Railroad(KNR). With this limited number of resources assigning locomotives to each trains of timetable is very important in the entire railway management point of view because schedule can be regarded as goods in transportation industry. On a simple rail network, it is rather easier to assign proper locomotives to trains with the experience of operating experts and get optimal assignment solution. However, as the network is getting bigger and complicated, the number of trains and corresponding locomotives will be dramatically increased to cover all the demands required to service all of the trains in timetable. There will be also numerous operational constraints to be considered. Assigning proper locomotives to trains and building optimal cyclic rotations of locomotive routings will result in increasing efficiency of schedule and giving a guarantee of more profit. The purpose of this study is two fold: (1) we consider a planning-level locomotive scheduling problem with the objective of minimizing the wasting cost under various practical constraints and (2) development of implementation prototype program of its assigning result. Not like other countries, i.e. Canada, Sweden, Korean railroad operates on a daily schedule basis. The objective is to find optimal assignment of locomotives of different types to each trains, which minimize the wasting cost. This problem is defined on a planning stage and therefore, does not consider operational constraints such as maintenance and emergency cases. Due to the large scale of the problem size and complexity, we approach with heuristic methods and column generation to find optimal solution. The locomotive scheduling prototype consists of several modules including database, optimization engine and diagram generator. The optimization engine solves MIP model and provides an optimal locomotive schedule using specified optimization algorithms. A cyclic locomotive route diagram can be generated using this optimal schedule through the diagram generator.

철도지명의 결정기준과 체계에 관한 기초연구

지명은 일정한 지역의 명칭이다. 지명의 발생 요인은 인간의 한 지점이나 지역을 다른 지점 또는 지역과 구별하기 위한 데서 발생한다. 철도의 지명은 철도역명과 노선명 결정시 민감하게 반응한다. 서울을 비롯한 대도시권 도시철도의 노선은 번호체계로 통일되어 있으나 간선철도의 노선은 다양한 성격으로 구분하여 노선명이 혼재하고 있다. 즉 기존선의 경우에는 역명이나 노선명에 혼란이 없으나 신선건설의 경우에는 사업명·노선명에 혼란의 소지가 발생한다. 철도사업법 제4조(사업용철도노선의 고시)에서 국토해양부장관은 사업용 철도노선의 노선번호·노선명·기점·종점·중요경과지(정차역을 포함한다) 그 밖의 필요한 사항을 국토해양부령이 정하는 바에 의하여 지정·고시하도록 의무화하고 있다. 본고에서는 이의 결정기준과 체계화에 대하여 논의한다. There are lots of examples for naming railway lines and stations in Korea. In general we can specify some type of principles for making names at the railway lines. The first rail line name made some decision considering the origin and destination name of city or region. The second type of a decision making is the location or service areas of that railway line or station. And other one is about the destination city or region of that corridor line. In this paper we classified the name of the railway line according to above three types of decision principles and then suggested the guideline and future directions preventing any confusion to make a new railway line name afterwards.

The purposes of this primary study are the selection of rail station and train operation management techniques for express-rail operation service at the conventional railway electrification. For these analyses, we used the KNR statistics and KROIS data of rail stations and train users by rail line. Therefore, we chose the important stations for express-rail operation of Kyongbu conventional rail line (esp Seoul-Jochiwon section) through the rail transportation demand, and then, suggested primary operational management plan through the effects analyses of decreasing total travel time and increasing transportation demand by train speed-up. This study has some bounds and limits for proceeding, as it does, we excluded as followings: the conditions of fare system, headways and train diagram, economic/financial analysis and technological assessment, and other railway technological infrastructures and a certain railcar specification, etc.. We propose to enlarge this study into a feasibility study of express or skip-stop operation service and compatible vehicle system decision considering with the best possible investment rail line, furthermore, in front of Kyongbu (Seoul-Busan) high-speed rail open in 2004, we have to try to progress the efficiencies of railway operation applying various train operation management plan.

철도시설의 효율적 활용을 위한 정비방안 : 도시의 공간확산과 철도역의 이전ㆍ정비

This primary study describes some proposition of restoration and rehabilitation of rail station and station impact area for efficient use. Therefore, I reviewed the functions and roles about rail station and other railway facilities related with urban structures and development, and also analysed the case studies about realignment of rail station, and then, suggested primary management plan of efficient railway installation. This study has some bounds and limits owing to the descriptive reviews but not detailed analyses. Hereafter, I am planning to consider the management plan for efficient railway installation use as coinciding with specific city characteristic and comprehensive plan such as rearrangement of the station.

This paper is designed the accessibilities at rail station and near facilities without distinguishing transportation handicapped or not handicapped people. Therefore, I would like to refer that this study is the just beginning such as the development for sustainable railway. This primary paper intends to present alternatives of trans-modal systems as the final goal in an attempt to set a direction for future policy making in the high speed rail sector. The alternatives recommended in this report stress two important elements for maximized utility of high speed rail at the station areas.

This comparative study means the case studies about not only coalition and partnership but also competition between high speed rail and other transportation modes. Therefore, I reviewed the each case about some countries and tried to develop for making some measurement. However, in this study, some bounds and limits exists owing to the descriptive reviews but not detailed analyses. Hereafter, I am planning to consider the management plan for efficient railway coalition with other transportation at the rail station and other terminal facilities.

In Korea, the number of railroad accidents is decreasing, but the scale of railroad accidents tend to be growing large. On considering the opening of the high speed railway in 2004, the problem of railroad safety is very important. The purpose of this study is to make plans for improving railroad safety of Korea. To make this plan, we generally analyzed the future railway traffic, and reviewed annual statistics of railroad accidents trend and case studies of foreign railway accidents.

This paper is designed (ⅰ) to envisage the characteristics of high speed rail stations that will be in operation when the Seoul-Pusan line currently under construction is completed and (ⅱ) to assist policy makers in mapping out transportation strategies by providing insights into how advanced countries have handled problems under similar circumstances. Ultimately, this paper intends to present alternatives of trans-modal systems in an attempt to set a direction for future policy making in the high speed rail sector. The alternatives recommended in this report stress two important elements for maximized utility of high speed rail: One is to maintain consistency in transportation policies and the other is to attract consumers to the station areas.

This primary study describes the strategies for expanding the railway market to overseas. Therefore, I mainly reviewed and analysed the report of KRRI. Hereafter, I referred to the world railway market analysis, and benchmarked about Japan, France and Germany for high speed rail system of their export strategies to the world. After than, I suggested some measures for expanding strategies through analysing the problems. According to opening the KTX from Seoul to Busan, we have to think what the next step is. Like other countries of developing the high speed rail system, we have to try to export some kinds of system for further technology and industry development.
