With the introduction of the RAMS(Reliability, Availability, Maintainability, Safety), the interest of the system assurance has been increased. First of all, fast-growing electronic circuit requires analyzing the failure rates, by dividing the signalling system more specifically. Since 2005, the K.N.R (Korean National Railway) has incorporated ERP(Enterprise Resource Planning) in order to establish the complete status as the top international comprise, therefore while ordering the project, it has established the classification system and then has been applying to ERP system in 2007. Due to the complex of the classification system, the reliability analysis of the signalling system was assessed with the limit of IXL ATP with On-board and wayside equipment. This paper assumed MTBF(Mean Time Between Failure), MTTR((Mean Time Between Repair) of total signalling system, by using the classification of ERP program.

Railway is used more than other public transportation since it has good punctuality and safety and securing safety is of importance as it is a mass transportation. But, train derailment due to the broken rail as a factor obstructing the safety of trains. Since a minute defect(crack) is often changed to breaking of the rail , we can identify the condition of occupation of trains by the detection of track shunt in existing fixed block track circuit when broken rail occurs. However, since recent CBTC(Communication Based on Train Control) systems is moving block trackless , it is impossible to detect broken rail. Thus, this paper examined domestic and abroad methods of detecting broken rail , developed and tested a monitoring system for rail breaks using optical fiber method, and proved it didn't have any problems to be applied to the field of railway.
