Abstract: Repoint is a new concept for track switching developed at Loughborough University. Through a novel locking arrangement it allows parallel, multi-channel actuation and pas-sive locking functions, providing a high degree of fault tolerance. The concept, based around a stub switch, offers several features that current designs are unable to achieve. The aim of the work presented in this paper is to evaluate the dynamic interaction forces due to the passage of rolling stock over the switch and, particularly, the area of the stub rail ends, in comparison to a conventional switch. Specific behaviour and load transfer conditions from one rail to the other at the joint are analysed, as well as long term wear conditions of the rails. These evaluations are undertaken by means of dynamic simulations, leading to design refinement of the stub rail ends.
