A railway is a complex system integrated with a lot of technical elements such as rolling stock, power, signal control, communications, tracks, stations, operation control systems, and so on. As a mass transportation system, a railway could contain potential risks that may result in a high death rate and property losses. Accordingly, Railroad Safety Technology R&D Corps. is adopting the plan of the construction of Railway Safety Test Facilities as a part of the Railway Total Safety Project to enhance the railway safety, and carrying out researches on effective project management methods with Systems Engineering techniques. To support that, we propose the more effectual management method of constructing the Railway Safety Test Facilities applying the model-based systems engineering tool to the research.

When it developes the railway system, safety is one of the most important and necessary things. SCADE SUITE has been used in many systems, like plane, transportation, nuclear power, etc, who have high priority to safety. This document introduces where SCADE SUITE has been used and describes how develope safety-critical system with SCADE.

In recent years, with the development of various transportation, railway evolved a lot. With advanced rail system, efficient communication system was required. for the delivery of accurate information of railway communications systems. Accordingly, railway communication system has evolved in a variety of ways. Cooperative communication method was proposed railway minimize the effects of fading in wireless communications and more efficient communication. In this paper, we present cooperative transmission techniques and channel characteristics and examples, and simulation results.

The objectives of railway construction and operation are transportation of passenger and freight safely and punctually. However, environmental effects such as noise, vibration, air pollution, underground water pollution and change of biosphere are emerged caused by train pass-bys. To avoid these adverse effects, new railway system has been developed around the world. This paper introduces LRT system and its environmental advantages. An environmental consideration for LRT design and adoptability for Korean situation are studied for the more.

Light-rail transit system has many characteristics of better accessibility. frequency service, low construction cost, reduced air pollution and medium-capacity public transport etc. Light rail transit system as a urban transportation system has been growing worldwide since the late 20th century. More than 300 cities around the world have light railway systems. Many medium-size cities in domestic site is planning the construction of light railway. This paper describes the development strategies for the light rail transit industry.

Economic evaluation methodologies for railway investments of China and Korea are comparatively analyzed. Chinese procedures specified in the new economic evaluation manual of 1997 were compared with those of Korea based on the economic evaluation manual of 1982. As expected those procedures reflect general economic requirements of the respective countries. Several differences in the specification are also noted. Details of the specification of Chinese procedure far exceed Korean specification, while Korean manual is rich of explanation on the fundamental theory. Differences in the procedure of calculating benefits of investments are most conspicuous, and specific requirements of carrying out a optimum opening year analysis in Korean procedure is notable. Despite of these differences in the procedure, two methodologies share same objective of ensuring selection of economically and financially sound railway projects. Both procedures of China and Korea, however, limit their evaluation scope on railways alone. Therefore, they are needed to expand scope of evaluation to encompass the idea of multi-modal or inter-modal evaluation, which will eventually contribute to build truly efficient national comprehensive transportation system.

This paper presents an evaluation method that considers the weights of many characteristics of a public transportation system; this method facilitates the selection of suitable advanced transit system in a transportation investment plan. The method sets up twelve evaluation items separated by the following influence factors: users, community, government and operators. It then evaluates the advanced transportation system by analyzing the weights. For an empirical analysis, the urban advanced transportation systems for the main transit of small and medium sized cities were evaluated using the AHP method. The result revealed that the weight order is safety, rapidity and punctuality, convenience, and regional activation, and the priority order is steel wheel-type AGT, LIM, and rubber wheel-type AGT.

Government has established and operated GIS Data Base in such fields as land-use, road, and underground facilities since 1995. Based on these circumstances, the importance of spatial information industry began to emerge and accordingly MLIT (Ministry of Land, Infrastructure and Transport) established "National Spatial Information Policy Master Plan" and "National Spatial Information Policy Action Plan". However, compared to other fields of transportation, the spatial information data base for railway facilities are not established and provided systematically. As shown in 'Korea National Spatial Data Infrastructure System', only 'transportation information' as an related information and 'transportation' field as an administrative information are included in the system. Detailed information for railway and its facilities are not included in the system. The reason why detailed information for railway facilities are not included in the system is that regulations for establishing and utilizing the spatial information of railway and its facilities are imperfect. In this study, trend of establishing spatial information and regulations related to railway and its facilities are reviewed. Through this review, improvement items such as complementing existent laws and establishing organization for managing spatial information data of railway are deduced and suggested. Based on this research 'Korea National Spatial Data Infrastructure System' could set a legal fundament and both integrated maintenance and operation of railway facilities could be possible.

Greenhouse gas and energy reduction goal management system is announced to reduce national CO2 emission in 2011. The target business sector of the system has to follow the procedure of the system and get the assessment. The percentage of the national CO2 reduction goad is 30 % compared to the amounts of BAU. In railway business sector, 6 bodies are included in this system so that railway industry cannot stay and sustain its better position any more than other transportation industry. Most of the industry except Railway industry is struggling to develop its product more environmentally friendly and get the 3rd party certification like Eco-labelling and Carbon footprint. To get environmental certification, LCA method has to be applied because life cycle approach is needed to respond current environmental requirement. The purpose of this project is to facilitate railway vehicle manufacturer obtaining the environmental certification termed Korea EPD. By doing so, the environmental performance evaluation tool would be developed and modelled within the LCA framework and therefore applied especially for rail vehicle.
