Abstract

The construction of railway turnout entails a complex geometry and multi-disciplinary engineering science, which makes it one of the most critical railway infrastructures. As such, these characteristics pose various risks in rail operation. A considerable number of derailment incidents at the turnouts are reported annually worldwide. Not only do these incidents cause operational downtime and financial loss, they also give rise to casualties and sometimes loss of life. One of the fundamental reasons for this may well be the fact that the railway industry pays little attention to the risk elements of railway turnouts. The paper, as state-of-the-art, provides an overview of how to deal with the many different risks arising from railway turnout systems by identifying the most/more suitable risk analysis methods for the systems. In order to do this, a large number of related articles, reports and review papers are critically analysed by virtue of comparison, experiences and deductions. As a result, various qualitative and quantitative based risk analysis methods are proposed to fully understand a number of technical phenomena, e.g. aging, degradation and signalling faults, in a railway turnout system.
