Abstract
Railway turnouts are fundamental mechanical infrastructures, which allow a rolling stock to divert one direction to another. As those are of a large number of engineering subsystems, e.g. track, signalling, earthworks, these particular sub-systems are expected to induce high potential through various kind of failure mechanisms. This could be a cause of any catastrophic event. A derailment, one of undesirable events in railway operation, often results, albeit rare occurs, in damaging to rolling stock, railway infrastructure and disrupt service, and has the potential to cause casualties and even loss of lives. As a result, it is quite significant that a well-designed risk analysis is performed to create awareness of hazards and to identify what parts of the systems may be at risk. This study will focus on all types of environment based failures as a result of numerous contributing factors noted officially as accident reports. This risk analysis is designed to help industry to minimise the occurrence of accidents at railway turnouts. The methodology of the study relies on accurate assessment of derailment likelihood, and is based on statistical multiple factors-integrated accident rate analysis. The study is prepared in the way of establishing product risks and faults, and showing the impact of potential process by Boolean algebra.

Summary
Derailment is an undesirable phenomenon causing damage to rolling stock and infrastructure as well as service disruptions, and which might cause casualties and harm the environment. These effects might result in serious reputation and financial losses to railway companies and organisations, as well as social, mental and economic consequences to the public. As for the situation in the UK, Network Rail has 21,000 track miles and 19,000 turnouts [3]. It can be said that there is one turnout per 1,14 track mile. A large number of derailments, accounting for 46% potentially higher-risk train accidents over the last 10 years, has occurred at British turnouts [4]. Causes of a derailment are often truck and turnout component failures, malicious operational failures, loading faults, environmental conditions, human factors, interaction problems or a combination of them [5]
