Current railway track design methodologies are mostly based on historical performance and developed from conventional track components. With the changing rail environments and developments of new technologies, an in depth understanding of track design theories and actual in-field performance is required for design accuracy and safety. This project aims to evaluate the existing track design methods to identify key track components and their effect on the track behaviour. In field measurements and video capture and analysis will also be using Digital Image Correlation techniques to verify assumptions in existing design methods. Finite element simulations will then be implemented and validated from the in-field measurements data. The effects of varying material and geometries properties of critical track components including subgrade, ballast, and sleepers will be analysed. The results of this project will refine design methodologies for efficient track structure and component design.
