Abstract
The invention relates to a head module for a rail vehicle, said head module being suitable to be detachably fixed to the front face of a subsequent railcar unit without additional underframe. The head module consists of an inner and an outer shell and includes three systems which convert, in the event of a crash, the collision energy into a deformation one after the other or simultaneously and substantially independently of another.
