A periodic inspection for facilities in operation is an inspection that is carried out regularly, in which inspection cycles are drawn up, and it is a series of tests to determine if the condition of all the equipment is maintained, and to identify whether they are to be used or replaced. Reliability should be enhanced, without a breakdown, by preliminary inspection and regular checks for each equipment item installed for equipment maintenance. It was noticed that there was a slight difference for the same facility, and for each organization in terms of inspection cycles and methods while preparing procedures of periodic inspection checklist, inspection methods and cycles for a related organization. Therefore, this paper reviews the optimal methods of inspection procedures for Seoul Metro.

Derail accident of train and motorcar through signal override causes such a huge obstruction in train service. To minimize such derail accidents, number of bills were examined such as installing normal and reverse position indicator on the switch. A indicator was necessary which does not affect current equipments and not to be confused as traffic lights. Normal and reverse position indicator is installed in the middle of the rail in front of front rod of switch. It is to prevent derail accident while manual handling of obstacle by ease of verifying normal and reverse position by attendants or motorcar driver. Also, it is a device that prevents accidents by indicating normal and reverse position of switch during night service of motorcar. Such a prevention accomplished through thorough maintenancework of equipment, precise handling of operators and exterior factors are eliminated or perceived and treated well.

We have studied on the possibility of precise positioning using hybrid Track Circuit system. Hybrid Track Circuit uses RFID which replaces UHF. Hybrid Track Circuit is a part of next generation railroad signal system which is available to communicate with a railway on board system based on a realtime operating system. If applicate on a current hand operating subway, phenomenon caused by driver's mistake such as passing a stop without stopping or mismatch error between PSD and train door should be prevented. 본 논문에서는 하이브리드 궤도회로를 이용한 정위치 정차시스템에 대한 가능성에 대해 연구하였다. 하이브리드 궤도회로는 UHF대역의 RFID시스템을 이용하고 실시간 운영체제를 기반으로 철도차상시스템과의 통신이 가능한 차세대 철도신호시스템의 한 부분이다. 본 논문에서 사용된 UHF대역 RFID 시스템은 원형편파의 태그와 리더 안테나가 사용되고 일체형 리더기는 송신출력 25dBm에서 우수한 인식회수를 얻었다. 현재 수동운행중인 지하철 차량에 이 시스템을 적용하여 정위치 정차를 하게 되면 기존 수동운전에서 기관사의 실수로 역을 지나거나 PSD(Platform Screen Door)와 열차출입문이 Mismatch 되는 현상을 방지할 수 있다.

Metro Subway System is widely known as the leader of public transportation in a metropolitan area. The signal interlocking is one of the most important organs that plays a major role in the system. By improving the quality of signal interlocking on of the traffic system and keeping its maintenance on a high level will not only repair the current state, but it will also let the PLC(Programmable Logic Controller). The Non-Vital relay of No. 3, 4 Line are the most one of the unstable system, device, which underwent a process of fine manufacture ? establishment and a close examination, obtained as a new device. Utilizing the equipment with cautious preservation on the system will enhance the current state of the signal device. Especially, the test for improvement and development based upon the technique that decreases the frequency of defect produced will further precipitate its efficiency. With authorization of imposing the newly made equipment will bring improvement to the signal technology and to the industry at largest extent.

The terms of track is a train-only line for a train service, in premises of station of a station, that the unit over the track for turnout the track from one track to another track, which it changes the course from the main track that is used for operating a train to the side track, is called a turnout The stick strength of tongue rail is adjusting uniform pressure on the both sides, the adhesion strength between a basic rail and tongue rail has to maintain over 100kg of power value to open over 1mm the ends. This study suggested developing a measuring instrument that can measure a basic rail and the stick strength of a movable rail in according with a switch, such as a switch point, and a performance test. This study ties to be helped that it improves measuring usability for the maintainers through improving quality in a stick measuring instrument, that it solves a technique in the site difficulties through improving a measuring instrument, with reducing the obstacles and expenses.

Memory-device is one of the auxiliary components of point-switch machine; connecting front-rod and tongue-rail. The right side and left side of memory-device are different from each other. When there would be a derailing accident of rolling stock or motor-car, the memory-device properly bends and protects the internal of point-switch machine. Memory-device is one of the important site maintenance spare parts. Memory-device for each of right and left side should be secured so that they can be installed on correct side during an exchange work. This study suggests the development of memory-device with different left and right side and the performance test of it. The study intends to contribute in the convenience improvement of maintenance by improving the unification of memory-device.

Railway signal facilities are very important because they are directly related to safe train operation. By the result of the unification of signal and station control, station control staffs have been having a hard time to grasp the knowledge about signal facilities and the fault restoration ability in a short term since the existing manuals were only made with text materials. To meet the growing demand to educate the maintenance work in actual and effective way, the maintenance manuals and periodic procedures was developed in the forms of video clips and animations with quality contents onto a DVD enabling not only to improve the maintenance works for signal facilities but to contribute budget saving and profit generating.
