  • With the opening of the KTX(Korean Train Express) in April 2004, Express Train service started in KNR(Korean National Railroad). Each KTX train consists of 18 passenger compartments in total, such as of 4 first class car and 14 standard class car. And 2 compartments of standard class are serviced as a unreserved seat only. The Unreserved seat system of the KTX is convenient to the customer who wants to take a train without making a reservation. This study was designed to analyze the unreserved seat system of the KTX which is currently used, and to investigate the necessary conditions for gaining in public favor by developing the system.

  • The launch of KTX (Korea Train Express) has brought the changes of people's life. People can get more time to work or enjoy leisure comfortably because the transfer time is decreased. According to these changes, the role of normal trains and express trains' drivers is getting more important. The purpose of this study is to suggest the advanced vision of Korean railway through comparing the domestic driver's qualification requirements of normal trains and express trains with international ones which are more developed.

  • The era of express train in Korea has come since April in 2004. The KTX(Korea Train Express) which has introduced the technology of TGV of France is regraded as good as the ICE of Germany or Shinkansen of Japanese in its hardware aspects. However there are still many things to be improved in its software aspects such as the quality of services, since the new express railway system is in the early beginning stage. To improve the quality of services, we should first measure and analyze the current level of the service quality. Using SERVQUAL model, the service level of KTX is measured and analyzed in this paper. Issues on how to improve the service quality are discussed based on the measurement and analysis.

  • A measurement system was developed in this study. It conducts on-line testing and evaluation of tilting train express(TTX). The measurement system is installed in each train for the performance measurement during the test run. It is composed of software part, hardware part and can measure various signals such as vehicle velocity, catenary voltage, motor temperature. The software controls the hardware of the measurement system, performs the analysis and calculation of measurement data and acts as interface between users and the system hardware. The hardware is consisted of 7 DAMs(Data Acquisition Modules) and 6 monitoring modules.

  • In order to control the railway noise, the radiation characteristic of the noise during the train passage should be analyzed. Generally, the major noise sources for Korean Train Express are the rolling noise and power unit noise up to 300km/h. In this paper, we describe on a train model that is considered to be a row of point sources to calculate the radiation characteristic. The calculation results are compared with short distance measurement. It is shown that the radiation characteristic of the rolling noise is dipole type. The noise generated by the power unit is radiated as the cosine type. The noise level at an observer is increased in the direction of motion and reduced in the direction opposite to the motion with increasing of the train speed. The calculation results including the moving effect of the noise source at 300km/h show in good agreement.

  • The purposes of this primary study are the selection of rail station and train operation management techniques for express-rail operation service at the convectional 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 thorough 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 conditionals of fate 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.

  • In express operation plans for urban trains, it is effective for the reduction of the number of sidetracks to apply a high performance train that has improved acceleration/deceleration ability and a regular train to local and express trains, respectively. In this research, based on a plan to use a high performance train for a local train, an optimization methodology is suggested to reduce the number of sidetracks and the operation time of the local train simultaneously. The optimization solver applied in this research is a genetic algorithm; headway, location of sidetrack and waiting time at the sidetrack are considered as design variables in the optimization problem. Consequently, by applying this system to Seoul metro line no.7, the effect of the suggested methodology was verified by obtaining the proper optimum solution.

  • In this paper, the crush characteristic of the tilting train express M-car was estimated under a head-on collision scenario. The car body was divided into three parts - front, middle, and rear. For each part, crush-force relation was evaluated numerically using LS-DYNA 3-diementional shell element analysis. This result will be used for one-dimensional collision analysis of the full train rake.

  • In the early construction phase of the Korea Train Express (KTX), the Movable Scaffolding System (MSS) for the top structure of the bridge was the predominant construction method. But the method had to be changed due to arising problems and an alternative method had to be found. Company H that participated in Korea Train Express construction project achieved excellent results of performance through the introduction of the Precast Span Method (PSM), which has been previously successfully employed in foreign express train projects. This study intends to verify the superior performance of PSM over MSS in the KTX construction process by conducting a comparative analysis on PMS and MSS based on the field experience of company H. This study will not only help to understand PSM, which is expected to expand its future scope of application, but also contribute to solve the problems of PSM that occurred during the construction phase.

  • This paper introduced an approach of improvement of performance of Electric device for EMU type Train like as TTX. The electric equipments are characterized by insulation, Noise, cooling system etc. and Their weight arc decided by these factors. There are two kinds of power source in EMU train. First, DC voltage source, 1500 volt, 750 volt is used for subway system. Second, AC power source 25000 volt is applied to high speed train and existing main lines. Composite material has the protection of inrush current and high frequency noise. We can use this material to minimize weight of train. Additionally we can get energy saving when operator service TTX.
