The seminar teaches the basics of track superstructure and the current technical status of modern track technology. You will receive an overview of the system requirements and applications of the track components. Especially looking at the force paths from wheel towards the subgrade and how to retain them within a safe level. Special track constructions such as transition zones, rail expansion joints, isolated rail joints etc. are covered as well as the basic requirements for the continuously welded rail (CWR) track and slab track systems as an alternative to ballasted track. In addition, the basics of track and switch inspection are presented in a rough overview (track measuring wagons, track gauges) as well as the possibilities of mechanical track and switch processing
