    Patent number: 11318967
    Abstract: The application relates to a crash system for the head module of a rail vehicle, said head module being detachably fixed to the front face of a subsequent railcar unit without additional underframe. The crash system has a crash conduction element that carries a crash box at its front end and the back end of which is fixed to the underframe support of the subsequent railcar unit. In the event of a crash, crash forces are thus absorbed by the underframe of the subsequent railcar unit.
