공항 철도 연계 시설 확충 사업에 따라 수색역구내에서 공항 철도로 연결선(L=2.2km)을 건설하고 신호 시스템 및 정거장을 개량하여 경의선 수색역에서 공항 철도로 경부선 및 호남선 고속열차(KTX)를 직결 운행 할 수 있도록 하였다. KTX/AREX 열차의 혼용 운행에 따른 AREX 전동 열차의 신호 시스템은 기존과 동일한 ATC /ATO 방식으로 운행하고 KTX 고속 열차는 ERTMS/ETCS L1 ATP 방식을 신설하여 운행하기로 하였으나 "고속 열차(KTX)와 공항 철도의 지상 신호 설비" 간 및 "공항 철도 차량(AREX)과 고속 열차용 ATP 시스템 지상 설비간 상호 간섭 등의 문제점으로 인하여 고속 열차 운행이 불가능하게 되었다. 이에 공항 철도 비콘과 KTX 열차용 발리스의 특성을 비교 분석한 결과 상호 간섭에 대한 기술적 보완이 필요함을 확인하게 되었다. 따라서 이러한 복합적인 문제의 해결과 기술적 타당성을 확인하기 위해 3가지 유형의 시험 모듈로 실제의 열차를 이용하여 시험을 함으로서 "고속열차(KTX)와 공항 철도 지상 신호 설비간" 및 "공항 철도 전동차(AREX)와 고속 열차용 ATP시스템 지상 설비" 간 상호 간섭 등의 문제점을 해소하고자 한다.

Recently, Statistical Energy Analysis(SEA) is being increasingly applied to describe vibro-acoustic behavior of complex structures, such as air plane, automobile, ship, building. In this paper, we discuss the application of SEA to predict the interior noise for KTX train. To validate the SEA model of KTX train, calculated the interior noise for motorized car is compared to measured one. Finally, the reduction measures of interior noise for KTX are also discussed.

2004년 4월 우리나라에 고속열차를 운행한지 5년이 되었다. 프랑스 TGV 열차를 한국형 지행과 환경에 최적으로 개량한 열차가 KTX 열차이다. 고속열차에 대한 연구와 개발로 차량의 외형적 장치 설계는 독자적인 설계 능력을 갖추었으나, 고속열차 열차제어진단장치 설계는 모방의 수준에 머물려 있다. KTX의 열차의 진단제어데이터를 분석하기 위해 VME 분석장비를 사용하여 수집하는 방법과 제어데이터구조를 분석하여, 열차제어진단장치에 대한 운용능력과 설계능력을 갖추어야 한다. 다양한 고속열차가 선로에 운용됨에 따라 철도운용자에게 필요한 다양한 열차제어진단에 대한 사전 대비를 함으로서, 고속열차 안전운행과 운용정비 절감을 위해 필요하다. 단일화된 열차제어진단 설계로 한국형고속열차 제작 능력뿐만 아니라, 운용능력 향상으로 고속철도 운영국가로서 위상이 확립되어야 한다.

High-speed trains with maximum speed of 300km/h, named KTX, have started revenue services since April 2004. Is becoming big problem where currently the KTX train because excessive braking noise at a station platform. The KTX braking noise follows in operating mode of KTX train and important railroad station where the quality appears different, the quality against hereupon from the commerce vehicle from the research which it sees it executes and comparison to analyze.

KTX train system is composed of TORNAD* network for transmitting information of train's internal equipments and OBCS which proceed information within train. OBCS of one trainset consisted of 28 equipments takes intelligent and dynamic composition according to equipment handling, train command and control flow. Each OBCS which is installed within trainset handle and supervise mutually action information about equipments, transmit it to driver to transmit information about train operation and preventive management. This mutual supervision and information transmission use KTX TORNAD* network system. TORNAD* network system is the one which is uniquely developped by GEC ALSTHOM, the KTX trainset manafacturing provider and this field is excluded from technical know-how transfer item. Through the research on analysis method of KTX TORNAD* system data structure which is operating on Seoul-Pusan Line, I hope that this thesis can contribute to train network system's standardization after applying it to improvement of train network system maintenance, enhancing quality of train service and applying it to future Korean rolling stock network system development.

This study suggest a way to improve duty process of KTX(Korea Train Express) high-speed train driver. A new operating system which based on safety was introduced to operate high-speed train which travel above 300km/h on the high-speed railroad but below 200km/h on the general railroad. There were some studies on the operation of high-speed train which travel on the high-speed railroad and on the general railroad with safety. However they overlooked the elements of human errors. The duty-load of KTX train driver's 14 basic operation processes was measured using NASA-TLX and found four processes with high duty-load. In this paper, critical tasks of the high duty-load processes are determined using a questionnaire. Some suggestions which include the improvement of facilities, operating system and operating skill are proposed to lighten duty-load of the critical tasks. The validity of the proposed new task processes is demonstrated by making question to KTX train driver. To use this results cost-benefit analysis, hazards analysis etc. should be performed additionally.

The purpose of this study is to verify the dimensions of service quality of Korea Train Express(KTX) and to compare the service quality of KTX with that of general train. The researcher consisted of initial 32 items representing eight-dimension and analyzed the final quality dimensions of KTX. The collected data of passenger of 226 was analyzed by statistical procedures such as the iterative sequence of computing Cronbach's a, corrected item-to total correlations, and factor analyses. Through the repeated statistical process to puritY the items, a final set of 26 items representing six district dimensions; tangibles, timely responsiveness, empathy, comfort, information access and safety. The Results of independent samples t-test showed that the mean scores of all the service quality dimensions of KTX except for comfort were higher than those of general train. This finding will provide the more appropriate instrument to measure the KTX service quality as well as to improve the passengers' perception of the service quality.

The KTX train which brings April 2004 high-speed railroad commerce operation time is operated currently Kyungbu line Seoul-Gwangmyeong-Daejeon-Dongdaegu-Pusan and Honam line Youngsan-Gwangmyeong-Seodaejeon-Kwangju/Mokpo. The high-speed railroad opening to traffic after KTX train interior noise follows in railway line quality change and it is changing together. From the research which it sees until opening to traffic after present time of the KTX vehicle it executed an interior noise quality change from Kyungbu line.
