As the requirements for overhead contact line systems increase due to higher train speeds, the need of safety equipment for these systems increases as well. Developing a component for the case of a contact wire cut to prevent further damage from the overhead contact line system requires an extensive knowledge about the system behaviour. Therefore, a comprehensive multi body system model (MBS) is developed in Matlab SimMechanics environment. In order to validate the datas generated from the simulations, a contact wire test stand has been constructed where cutting experiments can be run by releasing a pretensioned wire. Consequently, the force distribution during the contact wire cut is analyzed and these values are compared with the simulation results. For the comparisons, much attention is given to the period after the contact wire cut.
