Purpose: In the Korean railway infrastructure process, contractors and operators are involved at a later stage, which results in significant inefficiency. This study examines the benefits of early stakeholder involvement in Korean railway infrastructure projects and provides practical guidelines. Design, data and methodology: Literatures and foreign cases are analyzed. Building on the new product development model, we derive propositions explaining the relationship between early stakeholder involvement and the performance of Korean railway infrastructure project. Results: Major propositions include that early involvement of contractor has a positive effect on the project performance by shortening the infrastructure construction period and that early involvement of railway operator has a positive effect on the project performance by improving the effectiveness of railway infrastructure. Four requirements for the success of early stakeholder involvement are addressed. Conclusions: This study suggests that early stakeholder involvement shortens the construction period and improves railway infrastructure effectiveness. Academic contribution is to present the framework on railway infrastructure projects as holistic interactions among stakeholders. Practical contribution is to provide railway policy makers and other business practitioners with policy guidelines to improve railway infrastructure project process and to recommend an open access to relevant data.

As the prefecture railroad construction accelerates, unmanned system's reliability and safety is increasing in demand. Accordingly, effective management of construction projects for the PM and SE techniques are being applied, with the introduction and use of PMIS computerized systems. Due to the construction of railways, from the start of PMIS research planning, design, procurement, to construction and commissioning, various expertise is being carefully gathered, and by integrating it into the unified budget ideas and processes, rational, efficient, organized, and manageable financial plans are developed for the computerized system. However, the current PMIS does not take into account the life-cycle. This study is to bring attention to the BIM smart BOM-based configuration management for life-cycle through the consideration for railway construction project management.

It is no news that Nigeria's infrastructure challenge is enormous. In the global ranking, Nigeria ranked low in quantity and quality of its infrastructural provision which has a great impact on the ease of business transaction. Low investments in transportation have brought about the current infrastructural deficit. Recently, the Nigerian government has made effort to address at least to some extent the infrastructural deficit through Public-Private Partnership, but this has not yielded the desired result. Moreover, the sustainability issues relating to railway projects such as, emissions, noise pollution, ecosystem, and other environmental issues calls for urgent attention. Hence, this necessitated consideration on sustainability appraisal for the Chinese rail project in Nigeria. This study reviews sustainability of railway projects built by the Chinese firm in Nigeria with particular emphasis on the environmental and social impact of these projects. The study further identified issues and challenges in project implementation with a particular focus on civil dialogue and community engagements. A detailed literature search was conducted on railway projects and infrastructure by systematically reviewing selected published articles.The analysis of the selected articles identified sustainability issues and potential for improvement of Chinese railway projects and how they contribute to or inhibit competitiveness in the Nigerian railway market. From the literature searched, some of the projects constructed by Chinese firm revealed that there is economic and social impact of railway projects delivered by the Chinese firm in terms of capacity development and knowledge transfer potentiality. For instance, in the just concluded Lagos-Ibadan railway projects, the study gathered that the project brought about 5000 jobs and local staff were trained by the Chinese company, this will boost man power and local content capability. Also, it will significantly improve Nigeria's infrastructure and boost its economic development. The study suggests that Nigerian government should ensure and provide an enabling environment that is conducive for investment on the continent. Peace, improved security, and decent governance are the best conditions for sustainable transportation growth.

A railway is a complex system integrated with a lot of technical elements such as trains, track facilities, human factors, operation & control and maintenance. 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. Recently, various systems engineering tools such as CORE or Cradle are applied to manage the system requirements and the project management process in the part of the aerospace engineering and automobile engineering so on. The railway industry also makes an effort to develop an efficient management skills using systems engineering tools as the railway system is multi-disciplinary. Therefore, we propose the more effectual management method of constructing the Railway Safety Test Facilities applying the systems engineering tool to the research.

Railway is the most effective transportation than any other traffic. But due to the its expensive maintenance fee and various components like roadbed, rail, rollingstock, electric and signal etc, the construction cost of the railway is usually higher than highway. Such a reason, a lot of cost and period are needed to complete the railway project. In addition that considering the decreasing of the SOC budget, the investment in the railway industry is getting hard than ever. This study analyzed the cost, term of work, freight & passenger transportation demand of the wide area railway electrification project and main line improvement project. And it compared the estimation value and real value of the projects like cost and period etc. And this study surveyed the economic feasibility including factors which are not considered in the feasibility study guide. With those results, This study suggest the project management and evaluation method to enlarge the efficiency of the railway construction project.

In the construction phase, the existing schedule management system by 4D CAD has been difficult to check for a status and progress of construction product in real-time because it simulates only VR (virtual reality) object based on a planned schedule. This study suggests a construction schedule management system by telepresence technique that can visualize progress status in real-time by using 4D CAD system based on remote monitoring. The telepresence methodology and system were developed in the study and they were verified for a railway construction project. The developed system can examine the status and progress of construction because it can compare 4D simulation based on planned schedule with real-time site images through web-camera.
