Abstract: Railway networks are one of the major parts of the transportation infrastructure. Development of this network by the construction of new lines or the capacity improvement of existing lines needs time and capital cost. ...

Abstract: This paper focuses on developing train–track dynamic interaction models by consideration of ballast and subballast layers’ stress distribution patterns. In this paper, the existing railway track pyramid models are more ...

Abstract: This paper proposes a multiobjective optimization approach for a preventive maintenance scheduling problem. To model this problem, an optimization model was developed by considering two objective functions: minimizing ...
