Abstract

The Repoint joint is an innovative switch actuation concept where the rail design is inspired from the expansion joint. Because it is intended to operate as a track switch, the rails are redesigned to accommodate easy movement and a passive locking feature. This article examines the multi-body dynamic simulation model of this joint together with its foundation. The interlock feature of this joint is implemented in two variants, which differ only in its theoretical detail. The Manchester benchmark vehicle is run through it. The forces and displacement of the rail elements are similar in both variants.
