Reliability analysis of railway stations is a crucial topic in improving the performance of railway systems. This study aims to provide a comprehensive model for eva‎luating the reliability of railway stations using two methods: Markov analysis an‎d fault tree analysis. In this research, reliability parameters, including failure an‎d repair rates, are analyzed an‎d optimized to reduce failures an‎d increase repair rates. For modeling, the auxiliary equipment of the station, including trackside signaling equipment, has been used. The Markov model is implemented to simulate the behavior of failures an‎d repairs at the station, an‎d the results are compared with the fault tree model to validate the analysis. The results show that improving RAMS (Reliability, Availability, Maintainability, an‎d Safety) parameters significantly impacts station performance. The importance of this research lies in the fact that improving station reliability can prevent disruptions in rail operations, which not only increases safety but also reduces delays. In the first chapter, a general definition of the project an‎d the defined steps are presented, while in the second chapter, a review of studies conducted in this field is provided. Chapter three introduces the analysis method an‎d its steps, an‎d chapter four examines the results of the analysis conducted in chapter three. Finally, in chapter five, an overall conclusion of the analysis is presented, along with suggestions for future studies to further enhance the work.
