Nowadays stronger rules are applied to rolling stocks because of improvement of standards and thoughts to safety. So the designing lightweight rolling stock underframe structure is required to these rules. This review is about underframe structure which satisfies the condition of AAR Longitudinal static compressive force 360 ton comparing with difference of the former underframe structure.

A signal equipment improvement project for the existing facility ATS to ATP is under construction in Kyung-Bu and Ho-Nam commercial line including 400 rolling stocks. But there was a concern for the interface between KTX OBCS and ATP from the beginning of the project. At present, this is the front burner event. This paper introduces interface checking and predicted failure point between KTX OBCS and ATP improvement system. Through this measure the optimal installation of the ATP will be possible. The study was made under maintenance efficiency including reliability because the KTX signal equipment must qualify the above condition.

The aim of this study is to investigate the emission characteristics of volatile organic compounds from the interior materials of railroad rolling stock. Samples for VOCs were collected using a environmental chamber and the samples were analyzed for 35 individual compounds. 6 different types of materials, seat cover and flour material of Mugunghwaho, Saemaeulho and electric rolling stock were analysed. The results were expressed as concentrations over 12, 18, 24, 36 and 48 hours. VOCs concentrations were measured to be higher in the 12 hours than in the 48 hours. Floor material of Mugunghwaho showed the highest concentration of all studied materials. Followed by floor materials of Saemaeulho and electric rolling stock.

This study finds out and suggests success factors for the application of RIMS project through the case study of Seoul Metro and literature survey. The successful application of RIMS needs expert knowledge and concept of BOM, standardization of maintenance planning, check lists of heavy maintenance inspection, organization structure of rolling stock maintenance offices, material management system of warehousing and the process of parts repairing between offices, connection of material ordering system, problem solving of circular spare parts administration among inspection, maintenance, and material organizational units, systemic serial number management of parts with RFID, daily closing diary connected with work process chart, and sufficient period of RIMS's test run. RIMS contributes to real time management of rolling stock maintenance, transparency of management, reliability of train operation, customer satisfaction, and management innovation.

The rolling-stocks used in conventional line have suffered wheel problems due to lack of adaptability with track. These brought out severe wheel flange wear, these have caused unstable ride characteristics of rolling-stock. Especially, Wheel flange wear is severely influenced by wheel profile but lateral suspension characteristics. This study was started to induce wheel profile suitable for domestic railway environment. Thus, we analyzed the wear characteristics of wheel profiles that are being applied to railway rolling-stock in KNR. To analyze wheel wear characteristics, we have conducted experiment studies for passenger rolling-stock and obtained useful datum.

In this paper, we propose the ergonomic design method in shape design applicable for Advanced Urban Transit System. Human's sensitivity and User Interface of rolling stock investigated ergonomic studies of several type. The sensibility engineering design made approach of user center design in rolling stocks design. Therefore, we have application to properly of ergonomic design element in rolling stock design. we expert visual design and user interface help greatly in excellent rolling stock design.

In order to evaluate the sound transmission loss of a structure, a large reverberation room described by ISO is generally used. ISO test method is however for architectural structures, which is not properly implemented for small mechanical structures, such as rolling stocks. In this paper, evaluation procedure for railway vehicle structures has been proposed.

알루미늄은 중량대 강도의 비가 여타의 구조용 재질에 비해 뛰어나고 가공 및 용접성이 양호하기 때문에 수송수단의 경량화를 위해서는 가장 좋은 재질로 인정되고 있다. 또한 표면의 산화막은 내부식성을 향상시키므로 차량의 수명 향상에 기여할 수 있고, 우수한 재활용성은 환경 보전에도 기여할 수 있다.(중략)
