2018년 남북정상의 4.27 판문점 선언으로 한반도의 평화 및 협력 분위기가 조성되고, 그해 6월에는 국제철도협력기구(OSJD) 가입으로 한반도를 포함하여 중국, 러시아 등 유라시아와 연계하는 복합물류체계 기반이 마련되었다. 본 논문에서는 한반도와 유라시아를 효율적으로 연결하는 복합물류 네트워크 구축하는데 애로사항을 파악하기 위하여 현재 대륙철도를 이용하고 있는 실무전문가를 대상으로 설문조사를 실시했다. 설문항목은 국경통과 절차, 기술, 시설, 운영, 정부지원 측면 등 5가지로 나누어 애로정도와 해결 우선순위 점수를 조사했다. 그 결과 한국-유라시아간 국제 복합운송 문제점 중에서 우선 해결해야 할 과제로는 환적 시설을 개선하고, 통과국마다 검사하는 것을 폐지하고 통관서류를 간소화해야 하며, 운임변동을 최소화하는 방안 마련 등이 선정되었다. 결론적으로 한반도와 대륙철도 연계 및 복합운송 활성화를 위해서는 첫째, 국경에서의 궤간 변경을 원활하게 하기 위한 환적 시스템 개발을 국제 공동으로 실시해야 하고, 둘째 남 북 중 러 철도시설 및 운영시설을 표준화해야 하며, 셋째, 통관간 소화, 정기 발차, 운임 변동 정보 공유 등을 위한 남 북 중 러의 국제협력이 필요하고, 마지막으로 정부 차원에서 블록트레인 구성을 위한 물량 확보 방안을 마련하고 새로운 비즈니스 모델을 개발해야 할 것으로 판단된다.

'High speed' in today's railway is generally understood to mean 'regular revenue-earning operation of passenger trains at more than 200 km/h', and true high-speed services in this sense began in Japan in 1964. Today, Japan's high-speed rail network slightly exceeds 2, 000 km, carrying around 750, 000 passengers every day without any fatal accident for nearly 40 years.(omitted)

The measurement of contact wire wear in electric railways is one of the key test parameters to increase speed and maintain safety in electric railways. Wear caused by continuous interaction between pantographs and contact wires has a negative effect on current collection quality and severely damaged contact wires might cause hazardous accidents. This paper introduces a non-contact optical-based contact wire wear measuring system that will replace conventional wear detecting methods conducted by maintenance vehicles or workers. The system is implemented by high-speed cameras that can collect images of contact wires during vehicle operation, a laser used to create images profile of the contact wire surface, and a computer used to process the collected images. The proposed system is designed to assist maintenance of overhead contact lines by creating geometrically plotted images of contact wires to detect contact wire wear during operation on conventional lines or high-speed lines.

The total length of Korean urban railways reaches 1,200km. Urban railway used to be installed with ballasted tracks by reason of low cost at the time of construction, slab tracks are now being installed due to the reasons of the improvement in safety, lengthening service life and more economical method in terms of maintenance. The length rate of slab tracks has exceeded 70% of the domestic urban railways with the methods ranging from STEDEF, LVT, ALT, Eidan-type, B2S to RHEDA. This study surveyed the share of domestic slab tracks, and compared and evaluated the input cost at the initial stage by the types of slab tracks. Construction processes have been standardized by the existing design documents and calculated the initial input cost for the length of 1km of a hypothetical straight line. Cost breakdown structure was evaluated as materials cost, construction cost, equipment cost, indirect cost, etc. It is expected that this study will be used in selection & evaluation which is considering the economic feasibility of slab tracks.

The objective of this research is to explore the diverse challenges faced by the customer as well transport providers through the selected modes of transportation of the second most populous country in the world - India. Two separate well-structured questionnaires administered to garner the opinions on different challenges. A random sample of 100 equally selected from the customers of 3 modes of transportation along with 30 transport providers. The collected data was analyzed in Microsoft Excel and R Studio platforms using Percentile Rank Tool and R Programming Language for Chi-square test respectively. Traffic congestion coupled with parking is the major problem in case of roadways while Safety and cleanliness in railways are the first amongst the problems to reckon with. High fares and lack of trained employees are the biggest challenges faced by aviation industry. The research is concentrated only in the states of Andhra Pradesh and Telangana in India with most widely used three modes of transportation viz., Road, Rail and Airways. This research paper is first of its kind which has collected the opinions of both customers as well transport providers on the problems faced. This research proffers information about the challenges faced by the customers which there will be an enormous possibility to review their strategies and plans.
