Railway Track Design

This lecture covers the design of railway tracks, focusing on dimensioning the track components such as the sleeper, ballast, and rails. It explains the calculations for the load distribution, resistance to deformation, and stress analysis under the sleeper. The lecture also delves into the different types of materials used, like concrete sleepers, and the considerations for track structure based on traffic loads and speeds. The instructor presents a methodical approach to track design, including decision trees for selecting the appropriate materials and thickness of track components, as well as addressing issues related to frost depth. The lecture concludes with a practical exercise for students to apply the theoretical concepts learned.
