Railway switches are an important part of the rail infrastructure. Research has shown that the variation in some components of the turnout geometry has a great effect on the safety and reliability of the infrastructure. The purpose of this paper is to determine the risk/defects associated with switch rail, considering the switch panel (SP) and crossing panel (CP), because of the variation in the designed shape. An integrated analytical hierarchy process (AHP) with entropy objective weighting method is adopted to determine the weight of each risk/defect at different levels, based on the expert’s response. Analysis of the switch CP and SP demonstrates that wearing and plastic deformation of the switch SP are the most influenced risk-defects and can cause serious accidents at the railway switch. Two decision alternatives are presented, which include maintenance replacement of the system. The approach is a useful tool for optimal decision-making for infrastructure managers.
