Research NameDerivation of Empirical Formula for Railway Dynamics on Egyptian Railway Network (ERN)
Research DescriptionTrain safety and operational efficiency are enhanced by the ability to understand the behavior of trains under varying conditions. The aim of the research is to describe a method to develop empirical formula to calculate four railway dynamic concepts: Rolling and air resistance, Curve resistance, Coefficient of friction between wheel and rail, and coefficient of friction between wheel and braking shoes using operational data. To realize this goal, field survey and data were collected for track profile, rolling stock characteristics, train composition and the download of Automatic Train Control disc for some trips for different lines at passenger train types during the different seasons by analyzing this data, family of equations can be deduced and useful applications and recommendations can be proposed.
