Mobile radio technologies have evolved in the railway industry offering seamless connectivity and various functionalities to improve railway service. Recently, advanced mobile communication technologies have enabled a new level of railway customer services with more efficient railway operation. Since the LTE mobile communication technology offers many benefits and better performance for new railway services, it is considered to be a strong candidate for the future railway mobile telecommunication. However, communication networks in the railway sector are critical for secure operation and have stringent requirements for reliability and safety. In this paper, we explain the requirements for the future railway mobile telecommunication. The LTE, which would be the future railway mobile technology, is analyzed against these requirements. We also introduce the current state of standardization for the future railway mobile telecommunication and its implementation plan.

Recently many disadvantageous problems have been found during the process of domestic LRT(Light Rail Transit) projects and that can influence negative effects on the development of domestic railway. Since many projects have been progressed while having few original technologies, it is no exaggeration to say that they are being built unreasonable railway which lacks economic feasibility. The on-going LRT projects which are being carried out by the central or local government have a tendency to favor the systems and rolling stocks that have been approved by other countries through years of experience, therefore it can be said that we are having few chances to develop original technologies. In this study, we would like to promote railway development and jump up to the level of advanced railway standards through developing our unique and independent future LRT technology.

This study tried to figure out the future network of Korean railways in the 21st century. We suggest some pictures about the future network of Korean railways in terms of passenger railway and freight railway and hope that our pictures contribute to establish 21st century rail network in Korea.

The public, mass transportation, monopoly, speediness and the long distance transportation of railway have realized by representative advantage from former days. But realization for railway that is declining by industry on the decline by the 1970s since the 1st World War has been changing recently newly. Development of a technology and fast change of industry environment exerted big effect about traffic. And IT and wave in 21C that is spoken for to environment changed together paradigm for railway. Now, is forecasted that period 'Renaissance of railway' may set on the near future because road embankment is getting into the spotlight again by the future alternative among transportation worldwide. In this paper, characteristic of railway to move altered how, and paradigms of been rising railway quality wish to examine what it is newly.

This primary study has some bounds md limits owing to the descriptive reviews but not detailed analyses. However, 1 tried to do the comparative analyses and case studies about location and size of rail station for future efficient use of spatial structure. Therefore, I reviewed the location of railway station and some design standards of railway station facilities by type (high speed rail, conventional rail and urban rail), and also, suggested future direction for rail station as the core of city development relating with urban structures and human settlement system reformation.

Vehicle braking in non-electrified rail systems wastes energy. Advanced flywheel technology presents a way to capture and reuse this braking energy to improve vehicle efficiency and so reduce the operating costs and environmental impact of diesel trains. This paper highlights the suitability of flywheels for rail vehicle applications, and proposes a novel mechanical transmission system to apply regenerative braking using a flywheel energy storage device. A computational model is used to illustrate the operation and potential benefits of the energy storage system.

The railway project is an essential green transportation tool that is considered suitable for the domestic and foreign policy direction of carbon neutrality, but there are some limitations, such as damaging important carbon absorption sources during construction. This study analyzed the environmental impact assessment related to carbon absorption sources of greenhouse gas evaluation items conducted during the railway project, and limitations and implications were derived. The analysis of environmental impact assessment guidelines related to railway projects and carbon absorption sources dealt with prediction and reduction methods related to carbon absorption sources, but guidelines, including environmentally friendly railway construction guidelines, lacked descriptions. Since the greenhouse gas environmental impact assessment, 83 railway project environmental impact assessments have been reviewed, but in some cases, carbon absorption-related predictions have not been implemented, or carbon absorption-related reduction measures have been insufficient. In addition, there were cases where there was a limit to calculating emissions and reduction or where the reduction value was insignificant compared to emissions. In order to supplement the environmental impact assessment in the field of carbon absorption sources related to railway construction projects, alternatives such as quantitative emission and low reduction calculation, review of the no net loss system using the total environmental resource system, and linkage with climate change impact assessment are needed.

The article expounds that the speed competition is the motive force of each transportation means. It also analyzes the current condition of the speed of Chinese railways. The developing strategy for Chinese railway is to raise the speed of the existing lines as a primary step and to construct the high-speed railway in selected sections concurrently, which proved that constructing high-speed railway in Beijing-Shanghai area is the best choice.

If GNSS-based location information, expected to become the mainstream of the future technology, is applied to the future transportation, it will be of benefit to as follows; cost reducing effects on operating expanse and constructing expense due to decrease of ground unit installation, development of new technologies for train, or vehicle control system and becoming a front runner in the market. Therefore, this paper provides the minimum requirements for GNSS based system thru the studies on the applicability of GNSS based system to railway system, distinctions of the new technology between the existing technologies, and location accuracy.

This study have been reviewed Korea's railway system and railway cultural heritage status and suggested several solutions as a recognition of the importance of cultural property and development of the railway train had developed. Through the analysis of Japan's excellent conditions of a conservation and management of cultural heritage railway system, we would like to offer a direction of Korea's future heritage railway system. There were many changes during the time of a government owned railroad and the time after privatization in Japan by starting from administrating a systematic cultural railway at an institution that directly operates and constructs the railway train, which would be the point Korea need to approach considerately. Therefore, in this study, we would like to compare and analyse cultural heritage railway system between Japan and Korea and propose advanced solution for Korea's preservation of the Railway Heritage in the future.
