The railway signaling system consists of several vital computerized equipments. Now the project for development of signaling system for the next-generation high-speed train is progressed according to the consortium. The developing signaling system by this project, kTCS(Korean Train Control System), is composed of kTCS-CTC, kTCS-IXL, kTCS-ATC and etc. The KTCS signaling has to be operated as a integrated system by interface between each signaling. To achieve these, communication protocols between each signaling have to be designed and message codes are defined. In this paper the configuration of integrated kTCS system and designed communication protocol is presented.

The Light Rail Transit Project is a large scaled project which takes several years in building a system. After construction, LRT system is operating for several tens of years. For these characteristics, the right application of systems engineering to LRT project greatly effects the project success. In this paper, we present systems engineering application model to LRT project i.e. SELRT which include systems engineering technical process, core technology management process, project support process. SELRT also has a module for the exchange of outputs in SE tool and PM tool. Systems engineering processes in SELRT mainly base on ISO/IEC 15288. In future, we expand the range of SE processes and improve the usability in SELRT. We expect that this model will contribute to improve the efficiency in LRT project and to success the LRT project.

The Railroad Safety Technology R&D Program has been supported by the Ministry of Land, Transport and Maritime Affairs. The Program consists of dozen or more projects and thus is quite complex, which requires effective project management. This paper is discussing how to effectively manage the railroad safety technology R&D program based on systems engineering management plan (SEMP). The key issues dealt in this paper include the SE management, requirements management, verification and validation, integrated data base management, and traceability management. To achieve the goal, we first defined an appropriate SE process to be adopted in the program and the result was documented in the systems engineering management plan. According to the process defined, we set up the environmental frame in database. Using the database and SEMP, each project of the program was verified with respect to the corresponding requirements utilizing the traceability. All these efforts were carried out using a computer-aided SE tool, which enables efficient management of complex database.

As the opening of Korea Railroad Express on April 1, 2004, it has extended the transportation capacity of railroad, and decreased the time and moving cost. Railroad Express is industry composed of transportation, advanced technology, and grand project for synthetic plan. Hence, here now, as the anniversary of Railroad Express, we should analyze the overall effect of Korean Economy by KTX. relationship with other industry, social and cultural change. That is the key point what is the change during the year and how we catch the chance to develope the Korea Railroad for the national economy. The KTX has overcome the speed which the traditional railroad not been. But the Express has a weakness in searching of customer or goods. KTX is helped by electronics and telecommunications. so we need to find new industry in relation to KTX. And we should have open mind and vision for international railroad.

If the Seoul-Pusan high-speed rail project is able to open its revenue service in 2004, Korea will be the fifth country with an HSR system in the world. And, it will be recorded as a major milestone in the transportation history of Korea. But, Government regulated railroad fare because railroad fare increase can bring negative influences to CPI(Consumer Price Index). Consequently, Korea National Railroad cannot afford to operate railroad independently under current railroad fare system. In this paper, we studied the railroad fare system under implementation and its influences to CPI. And then we proposed that railroad fare must be decided by competition with other transportation modes and based on the demand variance by introducing YMS(Yield Management System).

Downtown traffic culture of the car focus of our country have developed. But, it was been interested in railroad to saturation of situation, environmental problem. Also, it is getting interest which is international by departure point of network connecting from Europe to Northeast Asia. Private capital project of railroad is activated but Construction companies payability is real that is worsen day by day. Therefore, Construction companies is destroying element enterprise's inefficiency and the waste, be interested in Project Management Information System as part of information. I wish to approach in efficiency of railway construction by presenting professional construction company's Project Management Information System.

As the delay of the Kyungbu High Speed Railroad, HST should use conventional line through Daegoo to Pusan until the new railroad build. High speed railroad noise is one of the main causes of environmental impact. Whenever HST on conventional railroad line is planned or a housing project near an existing railroad is proposed, an estimate of the relevant noise levels is usually required. For this, it is necessary to Quantify those parameters that affect the railroad noise. This paper deals with an estimation of high speed railroad noise on conventional line.

Railroad, the structure maintenance and restoration project was increased and widely performed in concrete pavement road and airport, building at downtown area, bridge abutment, and other concrete structures. Especially, the ground reinforcement technique by quick-reaction expansible resins is the most effective countermeasures against differential settlement and undesired deformation of structure. In this paper, the unconfined compressive strength and some environmental related tests were conducted to evaluate compressive strength and environmental effect of quick-reaction expansive resins and soil mixtures. Also, three case histories of concrete structure and railroad restoration project are presented. Based on the laboratory test, the quick-reaction expansible resins and soil mixture represent the sufficient compressive strength and the leachate material is satisfied the environmental regulation limits. As a result of this study, the structure restoration technology using quick-reaction expansible resins is very effective for restoration of differential settlement and deformation, and it is environmentally sustainable technology.

Maglev is a non-contact traffic system in which cars are supported by magnetic force instead of wheels. This is a ground-breaking traffic system providing superior environmental friendliness and cost efficiency due to the minimal noise and vibration offered by its non-contacting nature. We study the present specification and performance of the low speed urban maglev system in Korea and other countries. After set up the test line, to success the "Commercialization of Korean Urban Maglev System" project, we establish proper requirement of maglev system in Korean environment on base of "Daejeon National Science Museum Maglev Establish Project".

Nowadays there are lots of changes in the domestic railroad industries because of the reorganization in the industries, operation of KTX and expansion of city train in local areas. To cope with these changes effectively, domestic & abroad safety guideline and regulation were investigated and reviewed by railroad safety technical development project. Based on this project, domestic rolling stock safety regulation was established in the July and December on 2005. It's been a 3 years after 2005 and to confirm whether there are some problems to applicate the regulation in the field like korail, the necessity of reviewing the regulation gains force. In this study, to improve the field application in rolling stock safety regulation, we investigated the results of integrated railroad audit system and internal safety regulation system in a train operator and also collected the opinions from train manufacturer. Then through the result of investigation and collection of the opinions, we proposed the amendment to the rolling stock safety regulation.
