High-speed turnouts are the key components of high-speed railways. The crossing panel in the turnout is one of the critical zones where high loads occur when the train passes through. To reduce the dynamic forces during high speed or heavy haul trains passing, swing nose crossing designs are used. For those swing nose crossings, a drive and locking unit is used for positioning the crossing nose for the correct driving direction and to keep the crossing nose safely in position. To guarantee the correct position a detection unit is integrated into such a drive and lock unit. The focus of this paper is on the numerical simulation of the detailed swing-nose crossing together with drive locking and detection (DLD) devices and their behavior during high-speed operation. For this purpose, a dynamic model based on the Finite Element Method (FEM) is presented that enables to investigate the deflections and stresses in the turnout components as well as the dynamic behavior of the DLD system and its influence on other components during wheel passage.
