기존의 링크박스는 대부분 직매식으로 수침투 방지를 위해 케이스와 뚜껑 사이에 가스켓을 넣고 볼트로 체결하는 방식으로 사용하여 왔다. 이는 링크박스 유지보수 시 매번 볼트를 체결하고 해체하는 작업이 반복되어 현장 작업성이 떨어졌다. 이에 링크박스를 지상에 설치하며, 볼트의 사용을 최소화함으로써 유지보수 시 작업이 용이한 케비넷형 링크박스를 개발하였으며, 개발된 제품에 대해 전기적, 기계적 성능 시험을 수행하여 그 성능을 검증하였다.

The Technology Business of Next Generation High Speed Train being developed under a top speed of 400㎞/h in HEMU-400X to verify the performance of the commissioning tests will be performed in the Kyung-Bu High Speed Railway. To determine the requirement of developed rolling stock system compliance with the requirements of performance and reliability test is important, however, while driving to the maximum speed, we will find out the rolling stock dynamic performance characteristics, the rolling stock system and test track of the construct, and electric lines, signal facilities to verify compliance with the Interface and that is more important than anything. In this study, conducted tests on the train, while commissioning the interface with the ground facilities to be checked for suitability for each test item in any way and whether the procedure should be drawn for each of the considerations and requirements in the meantime, the international High Speed Train commissioning practices, safety regulations and enforcement rules, IEC, UIC as required by international standards, and the development of the rolling stock performance requirements were based on comparative analysis.

Since the "Low Carbon, Green Growth" as a social requirements is attracted public attention, the policies and investments of the railway which have been less estimated than road is re-considered. Since the starting the commercial service (2004. April), the KTX have been operated successfully while transport passengers over 100million for years. And also the project for development of KHST(Korea High Speed Train ; G7) had been accomplished with a good result, the first trainset of KTX-Ⅱ which base on G7 project was manufactured and testing now. On the other hand, the world's technology of the high speed train is more faster, and changing to a distributed traction system. To catch up the world's leading technology, the HEMU(High-speed Electric Multiple Unit) project will secure new technology and aims to promote the technology of domestic high-speed train. The authors indicates the result of detail review such as a curve, slope of the track and electrical dead section of the catenary to test at 400kph and also the performance simulation of the developed rolling stock in this paper. As the result, the authors devise the test scenario to perform a maximum speed test (stability at max. speed, acceleration & deceleration etc) with the restricted conditions such as track length, track available time etc by considering above result.

By the result of efforts for the technology development of G7 trainset, the technology of domestic high-speed train KTX-Ⅱ has lately been put to practical use while a forward countries of railway, which have their own developing ability of high-speed train, are competing against each other for the development of faster high-speed train system. Japan has been commissioning of FASTECH 360 which was developed in June 2005. Also France and Germany have been commissioning of next generation high-speed train such as AGV and ICE-3, developed basing on technology of their existing high-speed train system(TGV and ICE), its maximum commercial running speed is 360kph, and adopted multiple unit system. For the development of technology of domestic high-speed train and enhancement of national technology competitive power, HEMU (High-speed Electrical Multiple Unit) development project has been carried out as a national R&D project from last August. For the executing of HEMU"s maximum speed test, we have investigated the high speed line characteristics (i.e. radius of curvature, gradient, cant etc.) of Seoul-Pusan line and Honam line which is under construction. We‘d like to examine a study of condition for the best HEMU T&C line considering HEMU"s characteristics (i.e. acceleration, deceleration etc.) and its interface with infrastructure in this paper.
