The subject matter of the invention is a rail vehicle with a head module made of a composite fiber material. For this, a joining region with height-tolerance compensating means ( ) is arranged on the underframe ( ) and a joining edge with longitudinal and lateral tolerance compensating means ( and ) is arranged on the wagon body module ( ). The head module has joining edges that point toward the wagon body module ( ) and the underframe ( ) and is provided with reinforced sections ( ) that are integrated into the fiber composite material. The head module is attached to the underframe ( ) and at least at the head module side walls ( ) of the wagon body module ( ) by means of fastening means ( ), which build up a pre-tensioning force, in such a way that shear-resistant connections are created. As a result, it is possible to control size deviations resulting from the production methods in order to avoid undefined internal stresses during the joining, to absorb without damage the differing heat expansions of a head module of fiber composite material and a wagon body module, as well as to produce the head modules of a fiber composite material and the connections of said modules to the wagon body module ( ) and the underframe ( ) so as to be not only self-supporting but also load-sharing and easy to repair.
